3000 mailing list now quiet for a month

1725A Oscilloscope
The last recorded message on the 3000-L mailing list and newsgroup was posted on June 12. The five weeks of radio silence is the longest this information asset has weathered. The quiet isn't due to technical difficulties. A test message passed through the receiver and was broadcast to members earlier today.

The L, as it's been called informally by the community for more than two decades, has become a lean vehicle for technical expertise. It was once so full of chaff the community insisted on Off Topic handles, but an [OT] message has been virtually eliminated. The archives of tech wisdom — a big reason I believed the NewsWire had a chance at first — are still online, for now.

Some of the latest questions have been sharply on point for the HP 3000. Charles Johnson of Surety Systems asked last month how to program "a handheld PSC 6000 Plus bar code scanner installed as a wedge between a HP 700/92 terminal and a keyboard, all hosted on a Series 969SX."

In less than 10 minutes, Stan Sieler pointed Johnson at a programming manual for the device. Within the hour, another 3000 guru, Michael Anderson of J3K Solutions replied back. That's Johnson to Sieler to Anderson, if you're scoring at home, all within 45 minutes of posting the question. 

There's no problem with the concept of posting a question to a mailing list and waiting for a reply when the list is as well vetted as 3000-L. In the case of the scanner issue, of course, all three posters are already working as third party experts in MPE/iX systems: Surety to Allegro to J3K. There have been tech exchanges this spring where information flowed from one IT manager to another. That kind of list discourse is becoming more rare.

Sieler, who's done some pinch hitting for listserver administration in the years since list founder Jeff Kell died, has been in contact with the University of Tennessee at Chattanooga. The UTC campus hosts the server that holds this longest and deepest chunk of HP 3000 history, and Sieler has the contents archived.

Without Kell at the helm of the listservs at UTC, 3000-L is on autopilot. There's no one there to take non-automated requests. The community is at least aware that its greatest historical resource has an undetermined future. "It may only be a matter of time," said Tracy Johnson a few weeks ago, "before some before someone in IT management at UTC does an upgrade, migrates, or pulls the plug, and we're left in the dark."

Fine-Tune: Resetting your LDEV 21 Console

I have a 959 system at my site and there are times when I can't get the remote console port on LDEV 21 to work. How do I troubleshoot this problem and reset the console port? 

1. Is the port configured and available?

a) Check to be sure the system recognizes the port

:showdev 21

LDEV     AVAIL
     21     AVAIL

b) Is the SYSGEN configuration okay? 

:sysgen  sysgen>io
io> ld 21

LDEV:21  DEVNAME:  OUTDEV:21  MODE:  JAID
**ID: A1703-60003-CONSOLE-TERMINAL 
RSIZE:        40   DEVTYPE: TERM
**PATH: 56/56.1   MPETYPE: 16   MPESUBTYPE:  0
CLASS: TERM

c) Is the User Port configured in NMMGR?

:nmmgr
then ...

OPEN CONF, DTS, USER PORT

Logical Device [21  ]  (1 - 1800)
Line Speed [2400  ]  (300, 1200, 9600, or 19200 bps)
Modem Type [1] (0-NONE, 1-US, 2-European, 3 - V22.bis)
Parity [NONE] (None, Even, Odd, 0's, or 1's)

Holding on to 3000 data: this might work

Tape
As much as companies want to step away from legacy data systems, some are forced to make historical vaults of financials, customer profiles, inventory and much more. The HP 3000's current populace is full of this kind of work — knowing the answers to "what happened back then?" or maybe "how much credit did we extend to that company?"

Those questions sometimes mean that a computer that hasn't seen a new model since 2001, and an operating system that got its last update a decade ago, remains in charge of crucial data. Companies trying to hold onto the data face a few problems. They fall into two categories, hardware and software. (I know, that's almost everything, unless you consider networks to be another aspect.)

On the hardware side, getting elderly magnetic media to respond reliably will be a bigger problem with every passing day that a tape needs to slide across a drive head. It's not so much the tape itself, said Stan Sieler. It's the drives. Fewer and fewer people know how to repair the ones out there, too.

Tape was used as a backup for so long it's not natural to imagine disc playing a better role. But it does today. Your HP 3000 might need a System Load Tape one day for recovery purposes. When the SLT you've carefully preserved cannot be read by any tape drive, that mean be a hard stop for your historic HP 3000. Sieler suggested that an image of a 3000's startup volume, captured and stored on another disk, could do the same thing as an SLT reload. The 3000 would have to be fully quiesced to get the best image. But if it was not, the disc image could still work; it would just require an immediate reboot of the 3000. 

Those are circumstances that a historic records 3000 could withstand. A transaction processing system is harder to quiesce. The world still has 3000s processing transactions today, and for a long time to come.

Query Google about how to capture a disk image of a 3000's startup volume. Better yet, reach out to the 3000 support company for your datacenter. If you don't have one, here's an opportunity to correct that oversight. Reach out and get the assurance you need that your 3000's ability to report history will remain strong and clear. Do it before you're forced to find out the old tape drives won't read what you need to keep that server on duty.

Local advice guided bets for 3000 users

Interex Playing CardAt this summer's 3000 Reunion, close to two dozen friends and colleagues broke bread, watched video, asked questions and listened to advice. There was a local flavor to the visitor's register. There was also experience shared about what bets to avoid if you're homesteading.

Steve Cooper and Stan Sieler of Allegro were on hand, sharing advice and 1987 Interex playing cards (that was Stan, still a magician after many years, passing out a pack as he ducked into the meeting). Vicky Shoemaker of Taurus Software came in from Palo Alto, and Orly Larson drove five minutes from his Sunnyvale home. Tom McNeal was also local to the event, and Linda Roatch (managing newspaper servers at the San Jose Mercury News) was part of the contingent on the Orly Larson pre-conference night.

Everyone else at the meeting and the tour of the Apple Park HQ next door was an out of towner. Some were way out of town, from England or Toronto. Traveling used to be a part of the 3000 community experience, in the era before FaceTime, Skype, and texting. We once needed to be near one another to learn something or to share a joke.

Local storage, though, was discouraged in advice during that afternoon. In this case nothing could be more local than internal devices. Under the topic of Eliminating Single Points of Failure, users were advised to get rid of the single points of failure of internal peripherals for their HP 3000s. Be redundant. DDS tape drives and disk drives are better off outside of the 3000's cabinets. To be honest, tape media of any kind "is the bane of my existence," said Ralph Bagen of the MPE Support Group.

If you're using storage that was built in the last century, the advice went, you need to move to devices at least built in 2001 or later. You'll still need a tape to create an SLT, but just about anything on magnetic media is a problem waiting to happen. All hail cloud backup, or better yet, backups to Intel-based servers. Those might be servers hosting a virtual HP 3000 by employing Stromasys Charon.

Using MPE/iX to send SFTP files

I have a script that uses FTP to send files to a site which we open by IP address. We've been asked to change to SFTP (port 22) and use the DNS name instead of an IP address, and I don't believe the 3000 supports that. Does it? If so, how?

Allegro's Donna Hofmeister replies:

I'm not sure you want to do SFTP on port 22. That's the SSH port. SFTP is meant to use port 115. Have a look at one of our white papers on how to do SFTP on MPE.

If you are going to use DNS, you must have your 3000 configured for that. It's easily done. 

However, if you've never done anything on your 3000 to make it act like a real computer (oh -- that's right, it is a real computer and fully capable of using DNS), this can turn into a can o'worms.
