Friday Fine-Tune: Cleaning Up Correctly

Classic 3000 Advice
By John Burke

Good intentions about maintenance sometimes stumble in their implementation. As an example, here’s a request for help on cleaning up.

Cleanup-tools“We have a 989/650 system. Every weekend we identify about 70,000 files to delete off the system. I build a jobstream that basically executes a file that has about 70 thousand lines. Each line says ‘PURGE file.group.account’. This job has become a real hog. It launches at 6 AM on Sunday morning, but by 7 PM on Sunday night it has only purged about 20,000 files. While this job is running, logons take upwards of 30 seconds. What can I do?”

This reminds me of the old joke where the guy goes to the doctor and complains “Gee, doc, my arm hurts like hell when I move it like this. What can I do?” The doctor looks at him and says “Stop moving it like that.” But seriously, the user above is lucky the files are not all in the same group or he would be experiencing system failures like the poor user two years ago who was only trying to purge 40,000 files.

In either case, the advice is the same; purge the files in reverse alphabetic order. This will avoid a system failure if you already have too many files in a group or HFS directory, and it will dramatically improve system performance in all cases. However, several people on the 3000-L list have pointed out that if you find you need to purge 70,000 files per week, you should consider altering your procedures to use temporary files. Or if that will not work, purge the files as soon as you no longer need them rather than wait until it becomes a huge task.

Friday Fine-Tune: Split up MPE/iX versions

Multiple-personalitiesHas anybody had success trying to split a single HP 3000 system into two different OS versions by using two sets of disks? There is no need for sharing of information between the two operating systems, and they would run independently of each other at different times of the day.

Guy Paul replies:
This is certainly possible, as we have done this in the past for customers who couldn’t tolerate any downtime for OS upgrades. Hence, we came up with a solution to have a duplicate set of SYSVS discs that we upgraded while they were still on the old OS. Come day of the ‘real’ OS upgrade, we brought them down, stored off any modified files, switched over to the new OS, restored any modified files and they had an OS upgrade in about 45 minutes. So it is possible.

You should probably consider using BULDACCT to synchronize the accounting structure.

Gilles Schipper adds:
This should be entirely possible. I do this sort of thing all the time. By simply booting from the appropriate boot path, you can do exactly as you wish. In fact, I have even shared common volume sets among different LDEV 1 system volume sets, with different MPE versions.

What's the name and syntax of the Posix utility that allows you to assign a new file, give the file the same name as the one you're replacing—and the new file will replace the old file when the last user closes it?

Andreas Schmidt replies:
You want to use mv, a utility to rename and move files and directories. The syntax is

mv [-fi] file1 file2
mv [-fi] file... directory
mv -R|-r [-fi] directory1 directory2

Sendmail fine-tunes, if you still need delivery

By Andreas Schmidt,
with Mark Bixby, and Jens von Bülow

Relying on the HP 3000, you may want to use this box for incoming and outgoing e-mails as well. This is possible using a collection of software bundled with the HP 3000, or available in the public domain:

• Sendmail/iX, the mail transport agent well known on HP-UX that was ported to MPE/iX;

• Syslog/iX, the event logging subsystem required by Sendmail/iX;

• MAILX.HPBIN.SYS, the mail reader, and;

• Qpopper, the POP3 protocol for downloading.

Sendmail/iX and Syslog/iX have been ported to MPE. MAILX.HPBIN.SYS is part of the Posix shell part of each MPE/iX release since 4.5. The combination of all four of these utilities will enable your HP 3000 to receive Internet e-mails sent to [email protected] and send Internet e-mails into intranets.

Friday Fine-Tune: Tape to Disk, Posix time fix

C1539 tape driveEditor's Note: Monday is the Memorial Day holiday here in the Newswire's office. We'll be back with a new article on May 31. With every day that passes, HP's original hardware gets older and more likely to fail. Virtualization of hardware brings newer hardware into service with 3000s and helps with this problem, a risk that's greatest on the 3000's moving components. Especially tape drives like the C1539 above; even HP's discs are less likely to fail. Enjoy this advice on how to put stored data from tape into a store-to-disk file, as well as keeping dates accurate in MPE/iX's Posix name space.

I have some information on a tape. How do I create a store to disc file with it?

There are a few solutions. The first and easiest is to simply restore the info to a system (RESTORE *T;/;SHOW;CREATE;ACCOUNT=WORKSTOR) where WORKSTOR is an account you create to pull the data in.  Then a simple FILE D=REGSFILE;DEV=DISC and STORE /WORKSTOR/;*D;whatever else should create the disc store.

The second is to use FCOPY. The STORE format is FILE TAPEIN;DEV=TAPE;REC=8192,,U,BINARY.

How to Step Through a CSLT Reinstall

Stepping-stonesAssume you've seen your Series 918 crash to its bones. You replace the 3000 and need to reinstall from CSLT. Many a 3000 site hasn't done this in a long time. This is when you're getting in touch with your independent support company for advice and walking the steps to recovery.

Oh. You don't have a support company to call. One more thing that's been dropped from the budget. You could ask on the 3000 newsgroup for help, so long as your downtime isn't serious. This support strategy is one way to go, and James Byrne got lucky this week. One expert walked him through the critical steps.

"I am working my way through the check-lists for reinstalling from a CSLT," Byrne said, "and I have come to the conclusion this stuff was written more to obscure than to illuminate." The HP documentation advised him to boot from disk, something he couldn't do. "Fortunately this is a backup 3000, and nothing too bad can happen yet."

Gilles Schipper, our esteemed homesteading contributor, provided the answers. The problem lay in a bad boot drive, but how do you discover that's true? We'll get to that in a bit. First, the CSLT reinstall.

"Assuming you have no user volume sets:

1. Mount CSLT in appropriate drive and boot from alternate path
2. From prompt, type INSTALL
3. At completion, boot from primary path and START NORECOVERY (this is your second "boot".)
4. Mount whichever tape contains your directory (could be the CSLT or your latest full backup - if directory on both, use whichever is more current)
5. Log on as MANAGER.SYS and restore directory (:file t;dev=?;restore *t;;directory - note 2 consecutive;)
6. Use VOLUTIL to add additional discs to MPEXL_SYSTEM_VOLUME_SET.
7. Mount backup tape and:
:restore *t;/;keep;create;olddate;partdb

Reboot with START NORECOVERY

Ah, but what to do if you have user volume sets?

Friday Fine-tune: directories and tombstones

ByetombstoneA 3000 manager wanted to know about adjusting privileges on their server. When the community's veterans started to respond, extra information rose up. Some of was about the management of files in MPE/iX, the kind of legacy recorded on what's known as a tombstone.

Tombstones are data used to solve 3000 problems and establish file access. HP says in its manual for programming in MPE/iX that "It's frequently necessary to obtain status information on a file to determine the cause of an error." A File Information Display is frequently called a tombstone, providing:

  • Actual physical and operational file characteristics.
  • Current file information, pertaining to end of file, record pointer, and logical and physical transfer count. Information on the last error for the file and the last HPFOPEN or FOPEN error.
  • When a file is opened, the final characteristics may be different from those originally requested because of defaults, overrides, :FILE commands, and the file label.

You can use the PRINTFILEINFO intrinsic to print a tombstone. It requires that you specify the file number returned when the file is opened by HPFOPEN or FOPEN. The tombstone can display either a full or short format.  If the file is open, it provides a full display. Otherwise, it provides a short display. Calling this intrinsic does not automatically abort the program.

You can call the PRINTFILEINFO intrinsic from programs written in COBOL II/XL and HP FORTRAN 77/iX. When calling from COBOL II/XL, use the FD filename. You can call the name PRINTFILEINFO directly from HP FORTRAN 77/iX programs. You can obtain the required file number by using the FNUM intrinsic.

Tombstones came up after one list member resurrected an answer about privileges from a 11-year-old post. Ray Shahan, still managing archival systems for Republic Title of Texas, heard his name in discussion about TD and RD privileges and how to control them. He quipped about not being heard from in ages.

3000 backup strategy for closing Sundays

ClosedOnSundayEaster Sunday is on this week's horizon. While it's a rare day of closure at our local HEB grocery chain, Sundays are another sort of closure for 3000 managers. Nearly all of them want their partial backups of the weekdays to wrap up before the backup begins that will serve the work week. If you do full backups every night and want to make the new strategy to do partials during the week and a full on Sunday, there's a way to make that work. Donna Hofmeister, one of the former OpenMPE directors, explained the strategy in a message to 3000 managers.

First you need to decide what kind of partial you want to do.  On Tuesday, do you want to backup all files changed since Sunday's full backup or do you want to backup all files changed since Monday's backup?  (and so on....)

There are some things to think about here. If your "line in the sand" is always Sunday, then you have to deal with knowing that by Friday/Saturday your "partial" backup is likely going to be sizeable and will take longer to run. On the other hand, if you ever have to do a big restore, your restore plan is plan is pretty simple -- you'll need your last partial and your last full backup.

If your "line in the sand" is always yesterday, then your "partial" backups will be relatively small and quick. The flip-side is your big restore could be very complicated, since you'll need every partial backup through Monday plus your full backup. I think most people set the backup date as "Sunday" and do partials from there. But there's a technical bit that's also important.

Friday Fine-Tune: Creating the perfect CSLT

Editor's note: A classic technique, detailed here by the NewsWire's Hidden Value editor emeritus John Burke.

PerfectTapeA question about creating a CSLT for a Disaster Recovery test turned into a general discussion about what the perfect CSLT should look like. A system manager wanted to use the STORE option on the SYSGEN TAPE command to store additional files onto the CSLT he was creating for his DR test but was running into trouble trying to specify STORE options as part of the SYSGEN TAPE command. In particular, he wanted to simply add ;SHOW to get a listing of all files stored.

The answer to his original question is to use an indirect file, as in

sysgen>TAPE MODE=VERBOSE DEST=OFFLINE STORE=
^CSLT.INDIRECT.SYS

where the indirect file contains whatever STORE directives you want in addition to the file list.

One contributor recommended robust efforts to get a listing: “A backup tape is of limited value without a listing. For Disaster Recovery purposes it is also a good idea to have the original HP tapes and patches with you as it is possible to create an SLT that does not install or work on a different HP 3000 system.” This same contributor also suggested creating a disk file with a listing of all the stored files.

Puts, Gets, and Serving Up Transfers Faster

Server TrayHP 3000s are exchanging files with other servers, a process that's included the FTP protocol for more than 15 years. This capability was once so magic that the arrival of Samba file exchange on MPE/iX was lauded as a breakthrough. FTP is quite a ways off the most current of transfer protocols. One manager's started a discussion about how to improve transfer speeds to and from the 3000, though. He's using DSCOPY as well, but prefers the PUTs and GETs of FTP.

The advice that's current about FTP/iX says that hard-coding the 3000's ports (100mb full duplex, or 10mb half) is one way to speed things up. Ensuring your traffic is not running through a proxy (called "being proxied) is another idea. Measuring the speed of a PUT against a GET is one step in discovering why the 3000's FTP might seem slow.

In 2008, MPE/iX gained a secure version of FTP—at least part of one. This SFTP functionality arrived at the end of the Hewlett-Packard lab era for 3000s, a period when new tools were not being placed into wide use. Sites were locking down their 3000 scope of operations to ensure stability. The port of this then-current functionality fell short of complete: only an FTP secured client got created. PUTs could be secured, as well as GETs. But only from Windows, Unix, or Linux hosts to the 3000. The 3000 wasn't going to dish out files using secured FTP. There are notes in place to carry the work forward, though.

MPE/iX tools and components are also out there to complete this securing of file transfers. OpenSSH is the best-known protocol. A quick-start bundle can be downloaded from the MPE-OpenSource website run by Applied Technologies. There are SFTP installation instructions at Applied, too. Someone who's got a need for securing FTP transfers will need to do the server side of the porting, which was completed on the client side by Ken Hirsh, Mark Bixby, and Mark Klein. Requests to speed up FTP are a sign this porting would be more than just an open source hobby project.

Friday Fine-Tune: Moving all disks at once

I want to take all my disks, system volume set, and the user volumes, and move them to another machine that has no disks. How can I best do this?

Lars Appel replies

You might use SYSGEN to create two different config groups in the SYS account, one for the old system (e.g. CONFOLD), and one for the new system (e.g. CONFNEW). To create the new config you might start with one of the existing config templates, e.g. CONF9x8.SYS for 3000/9x8 systems. Use BASEGROUP to open it, adjust IO to your needs and KEEP it as CONFNEW.

7935Just make sure that every disk gets an LDEV in the new config. Paths and LDEVs (except for LDEV 1) do not need to be the same on the new system. MPE/iX will notice (and "collect") all available volumes during bootup (as long as they are "visible" by a configured LDEV number).

Shutdown the system, plug disks into the new box, power it on, boot from the primary path (or enter the appropriate path for LDEV 1) and at the ISL prompt do a START NORECOVERY [NOSYSSTART] GROUP=CONFNEW.

You might also need to adjust NMCONFIG with NMMGR as a different system will probably have the LAN cards at a different physical path. In case you make a copy of NMCONFIG, make sure it stays on LDEV 1 (FILE;DEV=1).

We replaced LDEV1 on our HP 3000, did an INSTALL. Then we did
RESTORE *T;/;DIRECTORY;SHOW;KEEP;OLDDATE
The MPE-filespace was restored normally, but the HFS filespace was not. RESTORE told me to use CREATE=PATH which I then did. The DIRECTORY is on my STORE tape - so what went wrong?

Wolfgang Kinscher, and Gilles Schipper reply:

If you are planning an install keep this in mind: Do not specify the option "DIRECTORY" with a partial (DATE>=) backup. STORE will not put the HFS directory structure on tape. Do the following instead: STORE ;*T;DIRECTORY stores all of your MPE/HFS directories on tape. Then do your partial backup without DIRECTORY option

After the install, first restore your DIRECTORY with RESTORE *T;;DIRECTORY and then restore your partial and your latest full backup respectively.


Friday Fine-Tune: Going Beyond JBOD

By Gilles Schipper

Mod 20sOne of the most cost-effective ways of advancing the reliability of your legacy system may be to replace your existing “JBOD” disk system with a much more reliable disk system. MOD20 units, still a better deal than individual disks, can provide a good starting point to implement RAID. JBOD is an acronym meaning “just a bunch of disks” — which would characterize the majority of HP 3000 systems as they were initially sold. JBOD disk systems comprise a set of independent — typically SCSI-connected — disks, which are each seen by the HP 3000 as a single logical device number or LDEV. Each disk LDEV is associated with a “volume set” and the failure of a single disk renders the “volume set” to which it belongs inoperable and un-accessible.

Traditionally, most 3000 systems have comprised a single volume set (specifically, the required SYSTEM volume set, with the brevity-challenged label “MPEXL_SYSTEM_VOLUME_SET”).

Systems comprising a large number of “JBOD” LDEVs increased the likelihood of system downtime, since the failure of a single, old disk effectively resulted in a “down” system — requiring a time-consuming disk replacement and system reload before the system could properly function once again.

To mitigate such delicate exposure to a single disk failure, many installations implemented the “User Volume Set” feature built in to MPE/iX, then constructed multiple volume sets so that the failure of a single disk affected only the volume set to which it belonged.

For practical purposes, the only real benefit to this approach was to reduce the amount of time required to replace the disk and reload only the data residing on the affected volume set. (In reality, it was usually quite unusual for a system to continue normal, or even minimal operation with even a single unavailable volume set).

When and how to back up 3000 directories

Editor's Note: Homesteading Editor Gilles Schipper weighs in on  using the 3000's store directory option, rather than invoking the buldacct program, to make clean backups.

By Gilles Schipper
Homesteading Editor 

CityDirectoriesIt's common to see confusion surrounding the use of the ;directory store option versus the buldacct directory creation program. In order to benefit from the store ;directory option, one has to utilize the option almost perfectly in both the store and the restore following a system INSTALL. Consequently, it becomes much easier to fall back on the buldjob options to re-create the directory -- although that option is inferior.

In order to be able to effectively utilize the directory option, the first thing that must be done properly is to ensure that the appropriate ;onvs= option is also used in the case where user volumesets are utilized. Otherwise, the non-system volumeset directories do not get restored after the INSTALL since they are not on the tape.

But even if the store part is done correctly, the other opportunity to go wrong presents itself during the reload process.

The proper procedure during reload is as follows:

1. perform INSTALL
2. restore ;directory from tape
3. re-create disk and volumeset environment via VOLUTIL

Then -- and this where many go wrong,

4. Again restore ;directory from tape (this re-creates the volumset directory environment on the master volumes for all user volumesets for those utilizing it)
and then
5. restore files
6. reboot with start norecovery (to enable network functionality)

Of course, for those that do not utilize user volumesets, the directory option becomes much less error-prone. And, for those that utilize third-party backup utilities, the ;directory option -- as utilized in the MPE store command -- is generally replaced with a similar option in the various backup utilities.

Friday Fine-Tune: Opening Up MPE's Shell

Way back in the middle 1990s HP added the Posix shell to the HP 3000. The improvement meant customers who had Unix and MPE running in the same shop could train operators and managers with a single set of commands. Posix was a plus, making the 3000 appear more Unix-like (which seemed important at the time).

Over the years, however, Posix has been a feature waiting be discovered for most 3000 managers and operators. The computer's operating system was renamed from MPE/XL to MPE/iX just for this added Posix feature. But enough history; Posix is still on the 3000 and remains a powerful interface tool, an alternative to the CI interface that HP created for the system. You can even call Posix commands from the CI, a nifty piece of engineering when it can be done.

That's not always possible, though. A customer wanted to know how to "expand wildcard shells" using Posix. He tried from the CI and had this story to relate.

:LL /BACKUPS/HARTLYNE/S*
ls: File or directory is not found

So how do I do this? I need to be able to tell tar to archive all of the reels of a STD STORE set via a regexp. It does not work in tar, and it apparently does not in ls—so I speculate that there is something special about the innovation of Posix utilities from the CI that I am not aware of. What is it?

Jeff Vance, the 3000 CI guru at while at HP, replied "Wildcards on most (all) Unix systems, including Posix implementations, are done by the shell, not the individual programs or in-lined shell commands, like ls in your example. A solution is to run the shell and execute ll from within.

Fine-tune Friday: Care and feeding of UDCs

Screen Shot 2017-02-06 at 1.53.00 PMMercury Insurance is a long-time HP 3000 shop still running a server in production. Last week Reggie Monroe reached out for a refresher on administration of HP 3000 User Defined Commands (UDCs). These are the HP3000's equivalent of scripting in Unix environments. UDCs are a better version of Command Files, according to Jon Diercks and his MPE/iX System Administration Handbook. UDCs are catalogued, Diercks says, so they can be loaded for individual user accounts.

UDC definition
Click for details

There's a superior PowerPoint slide deck online at the 3K Associates website that covers how to create and use UDCs. But the Diercks book (no longer in print, but available online) is more concise on the use of UDCs. It's also only available as an $80 book today on the used market; put yours in a safe place. Monroe's question asked about "a command to list all users, and the logon UDC associated with them, if one is set."

The initial answer was the command HELP SHOWCATALOG,ALL. This brings an administrator to

SHOWCATALOG [listfile][;USER=username[.accountname]]

But Alan Yeo pointed out that the MPE/iX command only locates system-level UDCs. 

You don't actually get what you think you asked for, so whilst :showcatalog ;user=@.@ sounds very hopeful, in fact it only shows the system level UDCs not account ones. As far as I'm aware the only place you can find them all is in the BULDJOB2 file in PUB.SYS. You do have a BULDJOB2 file don't you? And it's up to date?

And here's where Vesoft's utility does a job the 3000's OS cannot. VEAUDIT LISTUDC @.@ finds UDCs of all kinds.

Friday Fine-Tune: Memory and disk behavior

By Jeff Kubler
Kubler Consulting

Hard-disk-headAlong with the relationship between your CPU measurements and overall performance, memory and disk make up the other two components of your HP 3000 performance picture. Main memory is the scratch pad for all the work that the CPU performs. Every item of data that the CPU needs to perform calculations on or updating to must be brought into main memory.

The CPU must manage memory. It must cycle through the memory pages, marking some as Overlay Candidates (this means that new data from disk may be placed here), noting that some are in continued use, and swapping others out to virtual or what is called transient storage. Swapping to disk occurs when data is in continued use but a higher priority process needs room for its data.

To accommodate this higher priority process and its need for memory space, the Memory Manager will swap the memory for the lower priority process out to disk. The more activity the Memory Manager performs, the more CPU it takes to do this. Therefore it is the percentage of CPU used to manage memory that we use as a measurement.

Friday Fine-Tune: Logging, IP logins, SNMP

Due to a disk crash, I had to reload my HP 3000 system recently. I’ve just discovered that system logging has been suspended. How do I resume system logging?

Paul Christidis replies:

The reason for the suspension of logging was most likely due to a duplicate log file name. When the SLT was created the then-current log number was recorded, and when you restarted the system from your most recent SLT it tried to open the sequentially next log file. Said file already existed.

  • MOVE the existing log files to a hold area
  • Determine what logfile the system resumed on
  • Perform a series of SWITCHLOG commands until the logfile number advances to one more than the highest number in the hold area
  • Then move the held logfiles back to the pub.sys group — replacing the ones created by the series of ‘switchlog’ commands.

Is there a way to see the IP address associated with a particular login?

Any user with SM can do the following, for example:

:SHOWVAR HPSTDIN_NETWORK_ADDR;JOB=#S495
HPSTDIN_NETWORK_ADDR = 172.16.0.30

The command :listf ci.pub.sys,8 will list all sessions and will show their associated IP address.

I’ve got an older model HP 3000 and I'd like to start monitoring it with SNMP for things like CPU utilized, jobs running or whatever other cool stat I can SNMP-grab. The problem I have is I can’t find the MIBs for it anywhere.

Andreas Schmidt replies:

First of all, I do not recommend the use of SNMP on the 3000, for performance but also security reasons. SNMP is not the securest protocol, as you know. Nevertheless, here are some hints:

• In the group NET.SYS you will find the SNMPUDC. This should be set in any case for MANAGER.SYS or on system level.
• Having set this, a SNMPCONTROL STATUS will show you the status of the SNMP subsystem.
• SNMPCONTROL START / STOP are self-explaining.
• The MIBs specific for MPE can be found in the document HP SNMP/XL User’s Guide


Friday Fine-Tune: Login recovery strategies

We have changed passwords on MANAGER.SYS—and now we cannot locate the changed passwords, thanks to some staff reductions that made the new passwords unavailable. Any ideas on how to recover them?

John Stevens says

If you're logged on as OPERATOR.SYS, do LISTACCT on all the accounts that may have SM capability, then logon as the MGR/MANAGER of those accounts: TELESUP, and SUPPORT, and there are others; LISTACCT will find them. Login as those users (unless you don't have those passwords either) and LISTUSER MANAGER.SYS. Vesoft's MPEX might help ease some of this as well.

Duane Percox of QSS adds a simpler approach:

If you can log onto operator.sys:

file xt=mytape;dev=disc
file syslist=$stdlist
store command.pub;*xt;directory;show

Using your favorite editor or other utility search for the string: "ALTUSER MANAGER SYS"
You will notice: PAS=<the pwd> which is your clue.

Steve Ritenour suggests that a logon to the TELSUP account will unlock the passwords.

Some 3000 managers believe the subject itself should be filed in a place not easily found. "These responses are all well and good," said Bruce Collins of Softvoyage, "but shouldn't we be thinking twice about posting this kind of information (i.e. how to hack an HP 3000) to the 3000 newsgroup?"

Friday Fine-Tune: Driving Filesystem Checks

Space_odysseyIn the middle of a full backup, the HP 3000 at James Byrne's shop came to a system halt at 3 AM. It was the kind of halt that puts up those puzzling abort messages not even HP has fully documented. For example, about SA 1458, Robelle's Neil Armstrong said, "My experience with SA 1458 is that it is a catch-all abort. You need to look at the subsystem information and the only way to truly know the root cause would be to get a dump and analyze it." He referenced a webpage that breaks down the process of doing 3000 system failure analysis, too.

When a halt occurs during a backup, there's always the chance the 3000's filesystem has been injured. "I'd say run FSCHECK.MPEXL.TELESUP and check your filesystem," said Keven Miller of 3k Ranger. He added that a former HP support expert, Lars Appel, "instructed me that System Abort messages are in subsystem 98. From the MPE Error Messages Volume 2, Chapter 4, System Aborts, 1458 MESSAGE means A critical process is being terminated due to a trap."

Sure enough, power interruptions at Byrne's shop introduced damage to an Image database. 

We reached the point last summer were we were toying with going off-grid simply to avoid the repeated power interruptions. If this sort of thing is causing damage then we will have to consider it. And it seems to; we now have a broken backward chain in one of our Image databases. A thing that I cannot ever recall. Coincidence? We are doing a backup, and then I will be using Adager to go in and take a look.

FSCHECK is an included tool on the 3000. It's simply there to validate extents and scan the table cache for missing files. Better tools include not only the legendary Adager, but independent support suppliers for the 3000 owner. People who know the fast commands of tools like CSTM. "What does your support provider say?" asked one support vendor. Self-support can be backed up by 3000-L questions. Some of the advice about the halt even ran to looking at memory issues. A provider can help eliminate these possibilities.

Friday Fine-Tune: Print classes, STORE, FTP

I need to add classes to a printer on my HP 3000. I keep getting a message that the LDEV doesn't exist from SYSGEN's I/O section when I issue the ACLASS command. I can see the device exists, so what's the problem?

Letterpress-2Devices on your system that are configured through NMMGR must have their classes changed through NMMGR, which is probably why you're getting the error message. Run NMMGR and go to the PROFILE for the device. You should be able to add classes to the device at that point. After making changes in NMMGR, remember to VALIDATE these changes to NMCONFIG, and then cross-validate using the RDCC command from SYSGEN's SYSFILE section.

NMMGR changes take effect after the system has been reSTARTed and the power has been cycled on the DTCs. You should cut a System Load Tape (SLT) making these changes so you'll have them on tape for your next UPDATE.

If your device was configured through SYSGEN, the device should have its classes modified through SYSGEN. You're right, you do use the ACLASS command in the IO section. Changes to the IO section require a START to make them take effect.

In HP's MPE/iX manuals I am are directed to backup the system as follows:

STORE @[email protected],@.@.@-@[email protected];*T;DIRECTORY;SHOW

What is the practical benefit over

STORE @.@.@;*T;DIRECTORY;SHOW 

People trot out the reason from the distant past: if you have to do a re-install it is good to have PUB.SYS (and maybe the TELESUP account) on the front of the tape so you can restore quicker.

Gilles Schipper woke us up with his response. “The reason one would perform the former over the latter is to ensure that all of the files residing in the SYS account be placed at the beginning of the backup. Whether that is a good thing is, in my opinion, dubious."

Friday Fine-tune: Adding disks and IP blocks

Is it possible to add a disk drive "on the fly" without doing a reload?

Jeff Kell replied:

You generally have to shut the system down to install and cable the disk to avoid electrical/interface problems. The usual approach is to use SYSGEN to configure the new device on the path where it will reside, keep the new configuration, shutdown the system, install the disk and do a START NORECOVERY.

Once the disk is recognized by the system, you can add it to your running configuration as follows (assuming the new drive will be LDEV 5 in the system volume set):

:volutil
> newvol mpexl_system_volume_set:member5 5 90 90 (DISC,SPOOL)

[For details, see "Volume Management", HP Part No. 32650-90045 or "Performing System Management Tasks" HP Part No. 32650-90004.]

This will add the volume to the system volume set, but it also has some side effects. Since the new volume is "empty" and the disk space allocation routines attempt to "balance" loads across drives, all of your new files and transient space will be allocated on the new drive until it's capacity approaches that of the other volumes. This will create an I/O bottleneck on that drive, at least initially.

You could selectively :RESTORE certain accounts (or the whole system) to try and balance the allocation. You could also perform an INSTALL and a :RESTORE for better efficiency, but at the cost of a great deal of time. There are also certain third-party utilities that will balance disk utilization across members of a volume set. These utilities work online on a running system and don't require any downtime.

The network configuration of our HP 3000 was originally set up with one block of IP addresses. Now I need to add another block of addresses. Where do I add these in NMMGR?

You can add an IP address using NMMGR the following way:

  1. After typing NMMGR, select "Open Directory" .
  2. Then select "Update Dir."
  3. Now select the "Add" option (F5.)
  4. You are placed in a screen where you can enter the IP Address of the machine. The type is generally set to 1( IP).
  5. Now press the "Save Data" (F6) option, back out of NMMGR, and you are done.

Mailing news from the HP 3000: an old skill

Blue mailboxInternal mail hosts remain a crucial tool in datacenters, even some running MPE/iX. "You still host your own email?" is not a question you'd only pose to a crazy manager. An organization's security standards can be so high that no outside mail server will be trusted. In the earliest days of email, 3k Associates built and sold a beautiful native MPE mailing system, Netmail/3000. It's a smart mailserver, meaning it doesn't require that an organization's e-mail be piped through an Internet provider's mail server for final delivery. Then in the late 1990s, HP's lab started the long process of porting sendmail to MPE/iX.

Now some 3000 sites are looking at how to replace their 3000-based mailing software as they migrate. One of them contacted us this week to ask about an alternative to sendmail. Linux is their migration target, after a history using the 3000 that goes back to the days of HP Deskmanager. Tim O'Neill shared a story while asking about an alternative to sendmail.

I saw that FreeBSD Unix has its version of sendmail. Seeing reference to FreeBSD made me recall a story about FreeBSD running on an old HP 3000, maybe a Series 70 or an early Spectrum system. I think I have read that FreeBSD is at some sites still running in production mode, as MPE and MPE/iX are. It also made me wonder what the installed base of FreeBSD might be — and how that compares to the installed base of MPE and MPE/iX on old hardware and on Charon hardware.

FreeBSD, like MPE/iX, has some surprisingly large companies using it. You might have heard about one of them called Netflix. Of course the Charon HPA emulator from Stromasys makes every remaining product and archival 3000 a candidate for the kind of longevity we see in FreeBSD.

Sendmail has a colorful history. The Unix Hater's Handbook devoted a full chapter to the software's vulnerabilities; sendmail comes from the Unix heritage, after all. By 2003, HP was still patching sendmail to shut down security breaches, although the breaching wasn't nearly as serious on MPE/iX as on Unix variants including Linux. Sendmail's open source capabilities are now under the banner of ProofPoint, the company that purchased the sendmail resources in 2013.

Sendmail's worldwide release was last updated in 2014. HP announced it was testing sendmail to place in the Fundamental Operating System in November, 2001—a month that's famous in the 3000's history for other reasons. But the software moved along to an 8.13.1 release in FOS. It's only one major release behind the worldwide open source version, now advanced to an 8.14 release. Sendmail also includes encryption.

Friday Fine-Tune: Tricks with command files

I'm working on a command file on my HP 3000. Is there any way to have it copy part of itself into a separate (temporary) file?

Jeff Vance replies:

MPE does not support the Unix concept of ‘here’ files, where input data for the command can reside in the same file as the command, except in the case of jobs. But even in a job, you may not include inline data for a script or UDC invoked by that job.

The SPOOKHELP script may be of some use. This single script contains the help text for all of the SPOOK commands plus the code to search for and display that text once HELP xyzzy is entered.

How can we execute a command after a user enters the :bye command in MPE?

Olav Kappert replies:

It is possible to execute many commands after the bye has been entered.  Simply create a UDC (maybe a cmd file) called bye.

The contents of the UDC for the command bye is up to you.  This would be useful if you want to do statistics before the session terminates.

John Pittman adds:

Don’t let them do a bye. We don’t allow any users access to OP system prompt at all. They get a logon no break UDC that runs a menu, and when they end the menu, they get logged off.

Inside that UDC at exit time, we build a string giving user, connection point (LDEV or IP of their PC) connect time, CPU date etc and append it to a log file. Then we know when anybody last used the system, how many users are using different connections, or when different user names are using the same connection point.


Friday FineTune: Internal disk plus VA array

Human_pyramidFiberChannel Storage Area Networks and shared tape libraries became popular in the years after HP stopped making its MPE/iX hardware. The HP 3000 supports SAN from the XP series of RAID devices to the VA7100 disk arrays. But how much should you rely on a RAID or SAN device? Internal storage devices might seem to be yesterday's tools, but the modest drive inside an HP 3000 can still be very useful — even if a company has invested in the FiberChannel storage solution of the VA7100.

Moving to the VA solution has great benefits, as reported in a story about using a VA7100 array with the 3000s. But booting directly from a VA array — well, you'll need an N-Class server (native FiberChannel installed) or a very expensive HP A5814A-003 Fiber/SCSI router (if you can find such a thing) to employ VA in the 9x9s.

The Crossroads SA-40 Fiber/SCSI switch will link a VA array to 9xx 3000s. It just won't let you boot your MPE/iX system from any of its drives. Craig Lalley of EchoTech recommends the affordable Mod 20 arrays for boot capability.

Internal drives remain as important as the VA arrays for a Series 9xx HP 3000, or even to the XP line of HP arrays. Even important enough to even duplicate them.

Rebuilding Systems Faster and Better

I'm looking at how to save as much time as possible in rebuilding an HP 3000's software and directories. My options seem to be using STORE, versus the sysgen tape command "tape store=@.@.@". What's the best way to go here?

Donna Hofmeister of Allegro replies

Construction-loaderUnless your system is small (like a 918 with 8-12GB of disc), you don't want to try to do a full backup via sysgen. If you really do a full backup then I prefer this syntax “store /;...” as it is self-documenting and you know that the Posix files will be backed up as well. (On older releases of MPE, @.@.@ did not back up Posix files <eek>)

You want to make sure that you run 'buldacct' periodically (and routinely). You also want to make sure that you are somehow backing up your directory (store /;*t;directory, for example). Between the two, you have belts and suspenders (for recovering your accounting structure).

On older releases of MPE, you want to make sure that the network is shut down prior to making your SLT tape. And it's still a good idea to have the system quiesced when making an SLT, since everything in the sys account (and .pub.sys in particular) will be locked while the tape is being made. Nothing quite like grumpy users to make your day.

How to Make a Windows to 3000 FTP Move

Open-windowI need to move a file to our 3000 from a Windows server with FTP and Windows doing the put. The Windows file has longish variable length records, but I would like them converted to fixed length on the 3000. When I tried, this was the result:

PUT C:\Dev\MViewFTP\transdata\AP_HEADER_GW.CSV LMAPGW.IVD;rec=-1024,1,f,ascii,disc=1000;move

200 PORT command ok.

550 The FILE EQUATION STRING option (item# 52) is not in a valid file equation form. (FILE OPEN ERROR -449)

Keven Miller replies

Item #52 refers to HPFOPEN. From the intrinsic manual

52 File equation string:

Passes a character string that matches the file equation specification syntax exactly. (Refer to the FILE command in the MPE/iX Command Reference Manual.) This option allows the specification of options available in the FILE command.

I don't like the trailing ";move" in your command string.  I'd remove that. Also, you have comma after "ascii" and it should be a semicolon, like this

;rec=-1024,1,f,ascii;disc=1000

3000-L connects again after a silence

Tin-can-telephoneAs if on cue after our report about its silence, the 3000-L mailing list and newsgroup sprang back to life over the weekend. One problem solved by the 415 readers was how to identify if a store to disk backup is a LZW compressed backup file. A Tracy Johnson report also confirmed that a LISTF,2 can report the time of each LISTF, by writing a specialized job.

Meanwhile, a 15-year-old HP 3000 with network connection troubles got advice from the newsgroup's readers. A Series 969 running MPE/iX 6.0 would not be the first thing you'd choose for interfacing to an internal website. But when a 3000 has data that a user needs over the Web, the server is the place to go.

Trouble started to surface when clients access a webpage which then opens a telnet session with the 3000, grabs the info, and then returns the data to the webpage.

We’ve been getting more and more errors over the last year, culminating in non-stop Could not initialize data in path with TCP, which then blocked anyone accessing us through our webserver. We’ve tried many changes but cannot seem to get past this.

When it locks up, the HP 3000 keeps running but won’t accept any new sessions. Which means our clients can’t run searches.  Which is very bad for us. Sometimes we can stopnet and startnet and it will work for a while, but then the errors start again. Eventually, we have to coolstart to be able to have clients log in.

Dancing the Samba services tune, MPE/iX-style

Samba DancersTen years ago this week we were promoting instructions on how to use Samba better on HP 3000s. Samba is "a group of programs that allows a Unix host to act as a fileserver for Windows platforms," according the MPE/iX documentation rolled out in 1999. The file-sharing and printer sharing software which has been a part of MPE/iX since the 6.0 release "allows Unix-like machines to be integrated into a Windows network without installing any additional software on the Windows machines. Many different platforms run Samba successfully; and there are nearly 40 different operating systems which support Samba." And many more now, a decade later.

HP brought features of Samba to the 3000 in a port called Samba/iX. "It is a solution for those wishing to access HP 3000 disk storage and printers (both networked and spooled from MPE/iX) from common PC client operating systems like Windows." Samba/iX allows access to disk and printer resources of MPE/iX by providing standard SMB file and printer services that are accessible from PC clients and their applications. An administration tool called SWAT makes Samba so much easier to use.

Samba 3.0.22 is distributed by the following MPE/iX base patches. Your independent support provider should be able to help you round one of these up. They've got the latest functionality.

  • SMBMXY6D (BT) for MPE/iX 6.5
  • SMBMXY6E (BT) for MPE/iX 7.0
  • SMBMXY6F (BT) for MPE/iX 7.5

The (BT) stands for Beta Test. HP never cut the 3.0.22 version loose as a general release (GR) version. For reference, the following are GR versions with less functionality.

  • SMBMXG3A (GR) for MPE/iX 6.5
  • SMBMXG3B (GR) for MPE/iX 7.0
  • SMBMXG3C (GR) for MPE/iX 7.5

Even a total 3000 network newbie can get Samba up and running. Samba must be running before you can run SWAT. Here's some useful info when getting SWAT going.

In SERVICES.NET you'll want a line that reads:
swat   901/tcp   # Samba/iX Web Admin Tool

In INETDCNF.NET you'll want:
swat stream tcp nowait MANAGER.SYS /usr/local/samba/SWAT swat
(adjust the path to your SWAT NMPRG)

How to purge UDCs on the HP 3000 safely

Cheshire_catThe software vendors most likely to sell products for a flat rate -- with no license upgrade fees -- have been the system utility and administration providers. Products such as VEsoft's MPEX, Robelle's Suprtool, Adager's product of the same name -- came in one, or perhaps two versions, at most. The software was sold as the start of a relationship, and so the relationship focused on the understanding the product provided for people responsible for HP 3000s.

That kind of understanding might reveal a Lewis Carroll Cheshire Cat's smile inside many an HP 3000. The smile is possible if the 3000 uses UDC files and the manager uses only MPE to do a file PURGE. Of course, PURGE ships on all MPE systems. Using that means you'll have to rebuild the UDC catalog. But even that's not enough.

Stan Sieler of Allegro shared a story about this recently. "We recently encountered a site where—somehow—an HFS filename had gotten into COMMAND.PUB.SYS. You can't delete UDC entries with HFS filenames, nor can you add them. I had to edit the file with Debug to change the name into something delete-able." Then there's the rebuilding of the catalog. Keven Miller has contributed a program that sorts and reorganizes UDC files.

There is a more complete way to remove such things from a 3000's storage. You're careful about this because eliminating UDCs with only MPE might leave a user unable to use the server. That grin that lingers is the UDC's filename. 

User Defined Commands are a powerful timesaver for 3000 users, but they have administrative overhead that can become foolproof using the right tools. These UDCs need to be maintained, and as users drop off and come on the 3000, their UDCs come and go. There's always a chance that a UDC file could be deleted, but that file's name could remain in the filesystem's UDC master catalog. When that happens, any other UDCs associated with the user will fail, too. It might include some crucial commands; you can put a wide range of operations into a UDC.

When you add a third party tool to your administrator's box, you can make a purge of such files foolproof. You can erase the Cheshire Cat's grin as well as the cat. It's important because that grin of a filename, noted above, can keep valid users from getting work done on the server with UDCs. This is not the reputation anybody expects from a 3000.

Measure 3000 performance for datacenters

Hp-1715a-oscilloscopeMeasuring the performance of an HP 3000 used to be a leverage point for increasing investments. By now the numbers help justify continuing to use the server in a datacenter with newer boxes. "We think of our HP 3000s as stable, and even reducing in usage over time," says one systems manager, "though actually as the company grows, the data requirements and load on the 3000s increases."

One way to measure a 3000's footprint is the amount of memory it requires. Memory upgrades cost nothing like what they did even 15 years ago. But any spending at all makes that 15-year-old server suspect. HP's Steve Macsisak recommended sessions x 4, plus jobs x 16, plus 64 MB as the criteria for memory usage.

An HP 3000 uses as much of its memory as possible to make processing efficient. The design of the PA-RISC architecture makes memory the most important element of performance, after IO speed. It's not that unusual to see a 3000 using 100 percent of its memory, according to field reports. There's also CPU usage to measure. 

CPU percentages can come via the REPORT command. Count up the CPU seconds used in the week, and divide by the total number of seconds available (604,800). But for all of this, it doesn't feel like a graphic report the rest of the datacenter gets from its Unix and Linux systems using SAR. There may be a program inside a 3000 that can help, even if the company never purchased performance tools from Lund. HP's Glance gives away its reporting power in its name, one manager has joked.

PloticusThere's freeware available to create handsome graphs like the one at left, suitable for showing in a meeting about datacenter resources. Ploticus/iX was written by Andreas Schmidt. It uses data from SCOPE.SYS. Ploticus even works with SAR's data.

How to Use Input to Create Output Files

Intrinsics are a wonderful thing to power HP 3000 development and enhancement. There was a time when file information was hard to procure on a 3000. It was a long time ago, as I was reminded by Olav Kappert in a call about his HP 3000 history. "The high point in MPE software was the JOBINFO intrinsic," he said. Kappert started with the 3000 in 1979.

Fast-forward 37 years later and you'll find questions from a different programmer still working on a 3000, adding features to a system. The Obtaining File Information section of a KSAM manual on MPE/iX holds an answer to what seems like an advanced problem.

I'm still using our old HP 3000, and I have access to the HP COBOL compiler. We haven't migrated and aren't intending to. My problem is how to use the characteristics of an input file as HPFOPEN parameters to create an output file. I want that output file to be essentially an exact replica of the input file (give or take some of the data). I want to do this without knowing anything about the input file until it is opened by the COBOL program. 

I'm using FFILEINFO and FLABELINFO to capture the characteristics of the input file, after I have opened it. After I get the opens/reads/writes working, I want to be able to alter the capacity of the output file.

Francois Desrochers replies

How about calling FFILEINFO on the input file to retrieve all the attributes you may need? Then apply them to the output file HPFOPEN call.

Donna Hofmeister adds 

You might want to get a copy of the "Using KSAM XL and KSAM 64" manual. Chapters 3 and 4 seem to cover the areas you have questions about. Listfile,5 seems to be a rightly nifty thing.

But rather than beat yourself silly trying to get devise a pure COBOL solution, you might be well advised to augment what you're doing with some CI scripts that you call from your program.

Date format variable help for MPE/iX

What would be the easiest way to get a variable date in the format "06/29/16" on a MPE/iX 7.0 and 7.5?

Michael Anderson replies

First echo:

echo ![str("!hpyyyymmdd",5,2)]/![str("!hpyyyymmdd",7,2)]/![str("!hpyyyymmdd",3,2)]

Then setvar:

setvar mydate '![str("!hpyyyymmdd",5,2)]/![str("!hpyyyymmdd",7,2)]/![str("!hpyyyymmdd",3,2)]'

(Note the usage of single-quote and double-quote in the setvar command.)

Barry Lake adds

Please note that the HPYYYYMMDD variable is already a string variable:

Frodo: calc typeof(HPYYYYMMDD)
2, $2, %2

So you don't have to dereference it with ! inside double quotes. In other words, the following works just as well, is easier to read, and might even execute a bit faster:

Frodo: echo ![str(hpyyyymmdd,5,2)]/![str(hpyyyymmdd,7,2)]/![str(hpyyyymmdd,3,2)]
06/29/16

SLEEPER, Awakened for the Masses

Sleep-1389978_1280The contributed program SLEEPER is probably the software cited most often as proof of the riches of the Contributed Software Library. First created outside of the IT shops of Boeing (according to its first writer Ray Legault) the program was among the most classic of solutions for straightforward jobsteam management. You wouldn't mistake SLEEPER for something professional like Maestro, or even the free MasterOp. But SLEEPER was contributed to the 3000 community, not cast into the free wilds like MasterOp was after its commercial career ended. It was meant to be shared.

The trouble was, SLEEPER disappeared from the community's shelves when Interex died. The CSL tapes (and eventually CDs) went off the grid, another skid-mark left when the user group careened into the void in 2005. It's been 11 years, though, and it's finally time to at least make SLEEPER ready for a wake-up call. We've got the two simple source files to share.

Nobody has liability anymore for HP 3000 contributed software. SLEEPER was never released with support or a license; it was simply part of being an Interex member at a certain level. And let us take a minute to recall that Interex folded owing millions of dollars to members and vendors. After 11 years, it's time to make this software a community resource once more. "Hey, I know a guy who can get you that" has been the means to share the utility over the last decade.

Surprisingly, it's just a well-packed 184K of SPL and FORTRAN code. MPE magic never took up much space. That's one of the reasons it was magic. SLEEPER is also a fine example of how 3000 managers helped one another.

Recovering Your Lost Logins

BWManIn the world of 2016, losing a password can be a time-bending experience. Apple's ID logins for its iCloud services, iTunes, and App Store only bear five attempts at most before they close out access to the phone. From there, you're on to a lengthy call to Apple. The smartphone is a tiny computer. The larger ones are not as strident about refusing repeated attempts, including the HP 3000.

They are secure, though. In these times when the servers can go dark for awhile as cold-start archive systems, though, a login can get misplaced. We're not supposed to write these things down, after all. What do you do when you have a question like the one below?

I restarted a 3000 9x7 after a few years in mothballs to run an old in-house app. I was able to boot up and login as OPERATOR.SYS, but cannot remember or find the password for MANAGER.SYS. Is there anyway to reset, clear, or overwrite the password file? I know the old machine is a very secure one, but now I am hoping there is a way around it.

What follows are a couple of suggestions to get back into the manager's driver's seat. However, you'll need to at least have a ticket to ride in OPERATOR.SYS.

Gilles Schipper shares what he knows.

There's not an easy way around the security. But since you can log on as OPERATOR.SYS, you should be able to store off the system directory to tape, as follows:

:file t;dev=tape
:store command.pub;*t;directory

Now that you have the directory on tape, you should be able to move around with FCOPY (and its ;char;hex options) to find the password for MANAGER.SYS. And that's all assuming you haven't implemented the directory encryption feature available with HP's security product Security Monitor/iX.

There's one other way. It's a good thing, because the alternatives do not include a rescue call to HP. There's nothing like Apple's password recovery support left for the HP 3000, as the vendor has long ago left the field. However, a good support contract for an MPE/iX server can be just the thing, and we know where you can get one.


Tape drive changer a powerhouse for MPE

Autochanging HensAutochanging tape drives used to be the stuff of science fiction among 3000 managers, but those days passed by before HP cut off making Classic 3000 MPE V systems. Just because an autochanger is a 3000 storage option does not make it automatic to program, however.

A question posed to the community by Ideal Computer Services Ryan Melander reached for help on programmatically controlling such autochangers -- to select a slot, and load the tape and come to ready. "I am trying to configure an old DDS3 auto-changer, one that I don't believe will unload and load the next tape," he said.

Gilles Schipper noted that the command ad ldevno id=hpc1557a path=?? Mode=autoreply configures the device, and to advance tape after use, employ the command (from Devctrl.mpexl.telesup) ldev eject=enable load=online 

DAT tapesDenys Beauchemin mentioned HP's pass-through SCSI driver as a tool to drive the device's robot. The software was built by HP's labs and labeled as "not for the faint of heart" by engineers, but can assert a programmatic control over autochangers. Some third party programs such as Orbit's Software Backup+/iX can also do this work.

If ever there was a theme song for an autochanger at work, it would be a tune called Powerhouse. Children of the Fifties and Sixties will know it as soon as they hear it, if they've ever watched a Warner Brothers cartoon.

Options for STORE You May Not Know

StorehouseSTORE is the default backup tool for every HP 3000, but this bedrock of backup has options which might exceed expectations for a subsystem utility. Gilles Schipper, the support guru of three-plus decades on the 3000, told us about a few STORE sweet spots.

To start, using the :MAXTAPEBUF option can cut a four-hour backup to three hours or less. Schipper says that increasing the buffer size default to 32K, from the usual 16K, speeds up the backup when STORE sees MAXTAPEBUF. "That's a pretty good payback for one option."

Backups don't need to be specified with an @.@.@ command to be complete. "People should really be using the forward slash," he says, "because it's easy to accidentally omit the Posix file structure if you're not careful constructing your fileset backup." The slash is so much better that a backup specified by HP's TurboStore will replace any @.@.@ operation with "./" Combining @.@.@ with exclusions can lead to omitting files which should have been in a backup.

Schipper says that including a directory on a backup is smart, but private volumes in use on a 3000 need more than :directory as an option.

CPR for a Non-Responsive Console

On my HP 3000, after a short power blip, the console is now non-responsive. I can connect to the system's GSP port and the session is connected, but nothing is displayed. Neither <ctrl> A or <ctrl> B works. I type away, but get no response. I can then connect via VT-MGR and take the console :console !hpldevin and I receive all the console messages.

So, the messages are being sent (since I see them on the VT connection), but neither the physical console or the GSP gets any console messages. What can I try?

Gilles Schipper says

I believe a START NORECOVERY reboot is in order here. Since <ctrl> A <ctrl> B do not work, you will need to power-recycle the machine to effect a reboot. Presumably you would want to do this after gracefully stopping all jobs and asking online users to log off, if possible.

Depending upon which patch level your level of MPE is on, the :SHUTDOWN RESTART MPE command may also work from a logged-on session with at least OP capability.

Mark Ranft adds

If you haven't rebooted, I've seen similar issues. From the VT console can you try to do 'abortio 20' until it says no I/O to abort. A WHILE loop may make this easier. I've had luck with this in the past. But since Ctrl-B doesn't work, you may be out of luck.

How to Transform MPE Spoolfiles to PDFs

HP 3000 data becomes more useful if it can be e-mailed as industry standard report documents. After more than two decades of pushing at it, Adobe has made its PDF the de-facto way to exchange documents, even complex ones.

Which might have prompted this question from HP consultant and Suprtool trainer Jeff Kubler:

Does anyone have a lead on a tool that converts spoolfiles to PDF files? Are there any Contributed Library tools?

It won't be in the Interex Contributed Library (because the programs have gone underground; ask your colleagues if they have a swap tape) but the txt2pdf product works nicely to make this conversion. Even in its most advanced version it's about $1,000, at last glance. Bob McGregor reports as much.

Jeff, txt2pdf does this. We have a job that runs that:

1. Checks a pseudo device we have setup for any spoolfiles that are on the device with an PRI >0

2. If it finds a spoolfile, we convert it to PDF and move it to a server

3  Sends an e-mail to the streamedby variable telling them the PDF doc is ready on the server.

4. Alters the priority to 0 to mark it processed

We've been using it for a couple years, and it works great — of course, once we got the bugs worked out. What's cool is if someone delete the file, we just adjust the priority to something greater than 0 and it gets reprocessed.


Use GSP and More for 3000 ID, control

GSP boardThere's been plenty of change in the 3000 manager's life over the last 15 years. Some of the change is a little easier by exploring the use of the Guardian Service Processor. It can help in changing the location of HP 3000 consoles from one part of a shop to another. There's even a story out there that says the identity of the HP A- and N-Class hardware resides in the GSP.

Kent Wallace, while a 3000 manager for Idaho-Oregon healthcare delivery system Primary Health, needed to move his 3000 console.

I must move the 3000 console another 10 feet farther from the rack (it's an N-Class HP 3000/N4000-100-22). What are the 3-pin positions on the wire that I need to extend its RS-232 cable?

Our blog contributing editor Gilles Schipper chipped in with a solution offering even farther movement:

If you want to extend the range of the console to anywhere on the planet (at least where there’s Internet access) you could consider the HP Secure Web Console to replace the physical console. Depending upon the condition of your physical console, this solution may also save a bit of wear and tear on your eyeballs, instead of adjusting those pins.

Schipper wrote us a great article on setting up such a web console. The GSP is quite the tool.

Big files get zipped, moved on HP 3000s

ZipperA computer manager who's new to the HP 3000 is looking for CSL files this week. The Contributed Software Library is just an oasis to this IT veteran, something shimmering in his future that holds a highly useful thicket of utilities and more.

Someone in the 3000 community is bound to connect our new user with this CSL, for one reason: he's looking for MPE V programs to supplement his discovery of the emulated Classic HP 3000, simh. That's the MPE V-ready version of a virtual HP 3000: what amounts to a CISC skin for a 3000 on top of the simh code. Whenever the newbie connects with a CSL resource, if they've got their files on a 3000 they're bound to need to send about 24MB to him. That's going to require zipping them.

The act of zipping to compress for a transfer is an essential in 3000 management. Although the code for compressing files on HP 3000s is more than a decade old, like a lot of things on the system, it continues to work as expected.

Tracy Johnson, who manages the Invent3K server operated by OpenMPE, noted he's using the MPE/iX Posix shell's compress and uncompress. "It creates a file that ends in capital Z. Seems the compressed format is compatible with both GNU-zip and Winzip programs or any other Unix/Linux machine."

Lars Appel, who ported the Samba file sharing tool to MPE, offers a comprehensive answer. He points to an HP 3000 Web starter software kit that resides on a development server, open to the public.

3000-L breaks silence with DTC primer

DTC NetworkOn the verge of four weeks without a new message, the 3000-L mailing list and newsgroup delivered a primer on the control of DTCs on MPE/iX networks. A longtime contributor to the community set up a question about using these venerable devices that connected HP's terminals and other devices to a 3000.

I have multiple HP 3000s sharing one DTC.  My problem is, which one controls the DTC?  In the event of  a power cycle, there is a race between them for which 3000 will download the new configuration.  I need system A, my A-Class, to be in charge. However, systems B or C are most likely to download first, leaving me with the manual step of unplugging the network from B and C, power-cycling the DTC, and then waiting for the A-Class to download the configuration. Is there anything that can be done to just leave the A-Class in charge?

Tracy Johnson replied, "It's always been a crap shoot. I'm of the opinion the first HP 3000 to notice the DTC needs downloading will do the job. Which usually means the less busy machine." As it was just the first answer on the newsgroup, there was still a need to do unplugging.

21 days of radio silence on the 3000-L

Right_WirelessTelegraphThe slowing current of 3000 communication showed a fresh signal by the end of this month. As we write it's been 21 days since a message of any kind on the 3000-L MPE newsgroup. The resource that carried 45 messages during last February has 10 for the current month. All of this month's traffic was wrapped around finding resources: Brian Edminster of Applied Technologies and Vesoft support. Both were located.

However, the three weeks without a new message is new territory for the community's log of technical help and outreach by cohorts. Among those who were posting during 2015, several told us they're on the mailing list-newsgroup out of habit — rather than needing details for their datacenter's 3000s.

"I’m still on the list out of inertia, nostalgia and mild interest," said Dave Heasman, a UK IT manager. "My employer got rid of their 3000s and me in 2008. Bought a series of packages to replace a big bespoke brokerage/investment system."

Robert Mills said he "remained a member of the list, mainly as a lurker, to keep appraised of what was happening in the 3000 community. Except for three requests in September 2012, December 2014, and February 2015, I've only posted to the list when I felt that the 3000 knowledge I had would help somebody solve a problem." Mills said he retired when his company went insolvent in 2009, but he's kept his hand in IT.

"I have been involved with the GnuCOBOL (formerly OpenCOBOL) Project on SourceForge since October 2014, and decided to write a macro preprocessor that emulated the functionality available on the 3000," he said. "The preprocessor, CobolMac, is now in its 5th version (B.04) and has received good reviews by its users."

Others who contacted us said they haven't worked on the 3000 since the days that HP sold support for MPE/iX. "I have been a BizTalk developer full time since 2008," said Kent Wallace. "I needed to work, and this was the direction the world was going." The 3000-L still has more than 500 subscribers on its mailing list rolls, but much of the messaging comes from consultants and vendor experts, supplying answers to questions and tips. A total of 45 messages have passed through the list since the start of 2016. The IT pros like Wallace have taken the path to other platforms, first to HP-UX, then to Windows.

How hot plug disks can replace DDS offsite

300 GB Ultra SCSII need to find an alternative to DLT and DDS tapes for offsite storage. Sure, there's DS2100 and Jamaica drives. But a few $35 300GB Ultra SCSI drives would hold a lot more data with less points of failure. I'll set up a BACKUP_VOLUME_SET and use the internal disks to do store-to-disk backups of the system. 

I've always used my A-Class and N-Class systems with fiber-attached disk. Are the internal disk drives hot-pluggable? 

Jim Hawkins, IO maven for HP 3000 systems at HP, replies with details.

There are multiple layers of changes for actual hot plugs or swaps to work.  

  • You need the disk HDD to handle this electrically.
  • You need HDD physical carrier and physical interface to comply.
  • You need the system physical interface and receptacle to comply. 
  • You need your Host System Bus Adapter (HBA) to electrically support this.
  • You need the OS to be aware enough of the HBA to not get flustered by absence of the device and deal with any notifications from the HBA of the activity.   

Given that the N-Class disk cage has a screw-based cover and the HDD carriers have no quick release levers (as compared with HASS/Jamaica or VA7400) I would state definitively that there is no hot-plug intention.  

At the same time, the SCSI bus is pretty low power and low voltage, so it would be generally not-too-unsafe to experiment. But you're also close to AC inputs and they are not low power.

How to get specific about IP access for PCs

I want to give a 3000 a static IP, so I can permit a user to access the HP 3000 from that PC with that static IP. Is there a way to force a particular user ID to use a specific IP address?

Tracy Johnson replies:

A simple logon UDC should suffice:

IF HPREMIPADDR = "aaa.bbb.ccc.ddd" then
  ECHO Welcome.
ELSE
  ECHO Evil message here.
BYE
ENDIF

Bob Schlosser adds:

You can set up a logon UDC that checks that the var HPLOCIPADDR is equal to the device (PC) that you want them to use. Something like this:

LOGON
OPTION NOBREAK,LOGON
IF "!HPLOCIPADDR" <> "123.456.789.321"        change "123.456.789.321" to
your IP address
  BYE
ENDIF

Using this, we verify that the user is on the correct (assigned) IP address, and log them off if not.

The GSP makes the A and N worthwhile

GSP boardIt's a powerful part of an HP 3000 that runs whenever the server is plugged in. The Guardian Service Processor (GSP) is the maintenance control console commanding the ultimate class of the server to reboot, do memory dumps and even fully power down the 3000. Consultant Craig Lalley of EchoTech has noted the GSP has one fewer feature than its Unix counterpart, though.

"On HP-UX it is possible to reset the GSP from the host OS," he said. "I have not found a way from MPE."

From time to time a reset may be required for diagnostics services on A-Class and N-Class servers. If your 3000 gets loving care from a consultant or service provider outside your computer room, you may need a paper clip to keep up service levels.

The GSP can also reveal the 3000's speedometer, as profiled near the bottom of a webpage from Allegro Consultants.

The gap between 3000 and HP's HP-UX Integrity GSPs is a common shortfall of HP designs. Even though the 3000's MPE/iX includes a Posix interface, HP didn't engineer enough Unix into the 3000 to enable some administration that HP-UX users enjoy. (That lack of Unix can sometimes be a good thing when a security breach opens up in the Unix world.)

But when a 3000 needs a GSP reset, pressing a recessed button on the 3000's back will do the trick if a telnet command doesn't work. You can telnet to the IP address of the GSP, log in and do the reset. But you can also get someone to press the physical reset button at the back of the machine. It's recessed into the cabinet so you may need a magic paper clip bent just so.

Lalley calls the GSP, which HP introduced with its final generation of 3000s, one of the most useful things in the A-Class and N-Class boxes.

The GSP is a small computer that is always powered on when the plug has power. With it, it is possible to telnet to and BE the console. While multiple admins can telnet in and watch, only one has the keyboard.

It is possible to reboot, memory dumps and even fully power down the HP 3000 from the GSP. Use the command PC OFF.

It is probably the best feature of the N-Class and A-class boxes. The problem is sometimes it needs to be reset, usually with a paper clip. Since the GSP is a different CPU, this reset can be done during business hours.

 


Using Store-To-Disk for Backup Preservation

By Brian Edminster

Second of two parts

Yesterday I outlined some of the powers of the Posix program pax, as well as tar, to move MPE/iX backup files offsite. Here’s a warning. There are some file types that cannot be backed up by tar/pax while also storing their attributes:  ;CIR (circular) and ;MSG (message) files (and possibly others. I haven’t tested all possible file types yet.  Also, there is an issue with tar that is a fairly well known and has been discussed on the 3000 newsgroup. Occasionally it does not un-tar correctly.  It is unclear if and when this was fixed, but I’d love to hear from anybody that might be in the know, or which specific situations to avoid.

Regardless of these limitations, I’ve found a simple way around this. Use store-to-disk to make your backup, then tar to wrap it, so as to preserve the store-to-disk files’ characteristics, before shipping the files off-system. Later, when you retrieve your tar backups and un-tar them, you’ll get your original store-to-disk files back without having to specify the proper ‘;REC= , CODE= , and DISC=’ options on an FTP ‘GET’. I’ve been doing this for several months now on several systems, and I have not had any failures.

Backing Up Your 3000 Backup Files

By Brian Edminster
Applied Technologies 

Once store-to-disk backups on the 3000 are regularly being processed, it’s highly desirable to move them offsite — for the same reasons that it’s desirable to rotate tape media to offsite storage. You want to protect against site-wide catastrophic failures. It could be something as simple as fire, flood, or a disgruntled employee, or as unusual as earthquake or act of war.

Regardless of the most pressing reason, it really is important to keep at least some of your backups offsite, so as to facilitate rebuilding / recovering from scratch, either at your own facility, or at a backup/recovery site.

The problem comes in that the MPE/iX file system is far more structured than Unix, Windows, or any other non-MPE/iX file system-based storage mechanisms. While transferring a file off MPE/iX is easy via FTP, sftp/scp, or rsync, retrieving it is problematic, at least if you wish the retrieved files and the original store-to-disk files to be identical (i.e., with the same file characteristics: filecode, recsize, blockfactor, type, and so forth).

What would be optimal is automatic preservation of these attributes, so that a file could be moved to any offsite storage that could communicate with the MPE/iX system. Posix on MPE/iX comes to the rescue.

Migrating 3000 Data from Spoolfiles to Excel

I need assistance with putting an output spool file from MPE/iX 7.5 into Excel or other readable format. The file is generated by Query, then processed by Editor, then sent to the printer. Instead of printing it, I want to put it into a readable format.

MigratingI do not have QEdit or any smart tools on MPE, so my approach thus far has been to move the file to a PC before doing anything.  However, that carries with it the initialization sequence for the printer to which the job is spooled. The job is set up to print on a PCL 5 laser, which means it has hundreds of lines of control before the data starts.

Tom Moore replies

I would put commas in between my columns (in the query, or using Editor). I FCOPY from the file to a new file with NOCCTL to get rid of carriage control byte. You could also remove the PCL 5 lines by subset in the FCOPY command. Depending on the data, I would use EDIT3000 to change all " ," to "," and all ", ","," to compress the file, removing the spaces before and after the commas inserted above, then save the file for download to the PC.

I would also consider using ODBC to directly extract from the IMAGE database, rather than Query and all the subsequent steps. The HP free ODBC driver would do the job very well.

Birket Foster of MB Foster notes

Not only did we make that free ODBCLink/SE as HP's lab resource from 1998 to 2006, but we have continued to develop the ability to work with data in all kinds of file formats. We do supply 32- and 64-bit versions for ODBC to the HP 3000.

UDALink-MPE was designed for the HP 3000. We provide data in several different formats including XLS for Excel, XML, CSV etc. We can have a discussion about what you are trying to do with data; perhaps UDACentral is the right product for your challenge and we can organize a demonstration for you.

Studying the Scripts for HP 3000s

A recent question on the 3000-L mailing list and newsgroup asked for help on scripting. The question aimed at the automation prospects through terminal emulation programs. Does Minisoft/92 script, a manager asked. Of course, and Tracy Johnson replied to give details as well as an example.

Minisoft scripts are plain text files with a file extension of .s92 and can be assigned to function keys f1 through f12. We use the keyboard mapping config menu to map it to Type "Script".  Once you choose "Script" a blank box appears below where you put the magic words DO SCRIPT followed by a path including the file name.

Joe FridayLast week, the use of scripts also surfaced while talking to Birket Foster about data migrations. A client of Fosters runs five scripts to clean up phone numbers during a transfer of data. Being able to reach for the scripts improved the quality of data, and the work was automatic. the power of scripting reminded me of a fine column written for us by Ken Robertson. Its subject was an introduction for Unix administrators to the use of shell scripts. But the writing was the kind of operational lore that can make a 3000 look more powerful to an admin new to the 3000.  Robertson wrote about it for the Newswire.

The marvels of scripting lie deep in the roots of MPE. When HP expanded the OS to MPE/XL in the 1990s, it added the Posix shell, which extended the 3000's scripting potential. The MPE/iX command interpreter has a generous command set, pushing the shell into the realm of a true programming tool. Its ability to evaluate expressions and to perform IO on files allows the end-user to perform simple data-processing functions. The Command Interpreter can be used to solve complex problems. Its code, however, is interpreted, which may cause a CI solution to execute too slowly for practical purposes.

For the average task, the MPE scripting language is easier to read and understand than most Unix scripts. For example, command line parameters in MPE have names, just like in regular programming languages. Of course, there are several script languages on Unix and only one on MPE. On Unix you can write shell scripts for any of the many shells provided (C shell, Bourne shell, ksh, bash, etc). Although there is also a Posix shell on MPE, most scripts are written for the CI.

On MPE Chatting, B-Tree Plants and More

How we can chat on the HP 3000 system with the other users who have logged on?

Lars Appel replies:

You can try the TELL and TELLOP commands. For more information see :HELP TELL or :HELP TELLOP.

When I run dbutil.pub.sys, and type the command set MYDB btreemode1=on I get the message “Database root file must be at least “C”4 for SET <db> BTREEMODE1=O." Why can’t I set my btree mode?

Rene Woc replies:

Before you can “set btreemode1,” the database has to have Btrees. You add Btrees with “addindex MYDB for all (or specific master datasets)”. This command will also set root level to C4. To use “addindex” your system needs to be at least on TurboIMAGE version C.07.xx. So how do you find out what version of IMAGE you have? Use the version command in QUERY.

I need to take some groups off of the mirrored drives, and add (move) other groups onto the mirrored drives. Is it as simple to use the altgroup command and specify the volume set?

[Editor’s note: “mirrored drives” is a straw man that has nothing to do with the problem or answer.]

Craig Lalley and John Clogg reply:

It is simple but not that simple. What you need to do is create a temporary group on the target volume set. Copy files in the group you want to move to the temporary group. Delete the source group. Create the new group using

NEWGROUP xxx;homevs=volume_set
NEWGROUP xxx;onvs=volume_set

Note that it is a two-step command. Then rename the files from the temp group to the newgroup. John Clogg also noted that another approach would be to STORE the files, and restore them once the group was relocated. That way you could preserve creation and modification dates, and creator ID.

The Wide World of Connecting Storage

IO used to be more complex for IT. Sure, the array of choices for disk is vast today. But in the era when 3000s used to think they were lucky to get SCSI plugged into them, configuring disk connections was not simple. HP-IB protocol, built to link HP's instruments, was simple, used for all HP devices, and slow. But it was integrated and seamless compared to the SCSI of single-ended, fast/wide, and Ultra Fast.

Such was the case for one 3000 manager seeking advice from his colleagues. You never think about these things on a 3000 until the hardware breaks. Or backups fail. Or storage media gets rare. Aging hardware is one of several issues that require expertise, even if a 3000 runs the ultimate 7.5 version of MPE/iX. Our manager hunted for his help on the longest-running 3000 classroom in the world, the HP3000-L mailing list.

A single-CPU A-Class was moving away from DDS technology, the DDS-3 that was first launched in the '90s. There are other options for 3000 tape backup. But these options include single-ended, fast/wide, and other cable and termination combinations. DLT technology, introduced more recently but still a 1990s choice, runs with HP 3000s. It helps to get the ends right, though, if DLT is to have a new beginning on an old-school 3000.

"Until now they have done their backup on DDS," a manager talking to the 3000 newsgroup explained. "Lately they had a failure on the DDS drive, and have realized that it is getting difficult to get new tapes. They have decided to move to DLT8000, model C6378A, and have bought two of them. One is supposed to go live on the 3000, and the other to be stored as a spare device."

The DLT is hooked to the Ultra Wide SCSI interface on the A-Class. But ODE/Mapper doesn't recognize the device."

There was an error, and no DLT joy. Soon enough, one veteran consultant said, "You will have trouble connecting a fast wide SCSI device to an ultra-wide SCSI controller." It wasn't a rookie mistake, but the veterans who still prowl 3000-L had a solution and even a link to an inexpensive fix. So it goes, here in the fifth decade of HP 3000 mission-critical service. Answers are everywhere.
