Bridges to Cross Before Useful Emulation
It's been a month since the community got its hands on a freeware version of the Stromasys emulator. Some reports from these freeware testers have emerged. But the next installment of this saga comes from more installations and software license agreements. An MPE license is in place, but the subsystems such as COBOL II are not covered. More bridges lie ahead for this software to bring some homestead systems back to the future.
One example reported to me came from a manager of healthcare 3000s, all doing work with customized code in a healthy-sized datacenter. The company hears the clock ticking on the life of their MPE commitment. The veteran manager there, already experienced in the consulting world, says some more time needs to elapse with success stories and production testing before his employer would consider HPA/3000 as a new path toward some extra years on the 3000.
He approached the freeware release with gusto. I heard from him more than two weeks before the pre-Christmas unveiling of the A-202 version, crafted to two users only and licensed for non-commercial use -- unless you're evaluating it for production purchase. "I downloaded the emulator as fast as I could the Monday that it became available," he said two weeks ago.
I've been playing with it since, and am currently looking for a new (to me) computer to host it. My current computer is an Intel i3 Core with 6GB of memory. The emulator runs fine on it, but I'd like to find a computer that I can dedicate to the emulator, so that I can have my desktop PC back.
So far I'm happy with what I've seen and have run into only one issue. That being, accessing a remote tape drive. I'll get back to that issue later and gather more info, because I'm not sure of the cause.
I hope to get a copy for my customer so that we can demo it, and hopefully get them to buy a license. But we've got a ways to go before that happens.
Indeed, one vendor of software for the 3000, who's also helping companies migrate, said he's still concerned about protecting his products in a HPSUSAN license strategy that revolves around a USB key. It's a design that is just one removal of a thumb drive away from stopping a production machine, although Stromasys could replace that key in a matter of days, or maybe even hours.
The issues with licensing third party software remain untested, although Robert Dawson in Australia got Cognos software and some other packages transferred without incident. He left his reseller of Cognos to do the finagling. There's plenty of software tool support from the likes of Robelle, Minisoft and more, but application vendors are still in the process of letting their emulator policies be known.
In case the replacement of non-MPE versions of things like healthcare software doesn't go as smoothly as planned, there is an important place for HPA/3000, even in migrating shops. But while an emulator's lifespan is measured in decades, there are only fewer 3000s running as the calendar pages of 2013 flip away.
It needs more than technology success. Out front and obvious commitments from app companies in the 3000 space; controlling virtual disk behavior that might let multiple copies of software run at the same time (a concern voiced by two veteran MPE companies); file transfer that needed to be addressed by a tool from indie software consultant Keven Miller of Ranger 3K; a lack of testimony in regard to scaling the solution -- there is much to document and announce about this invention in order to give it wings in 2013.
We hope there's good information on all this coming out to retain 3000s in production status, using the emulator. The alternative is a freeware hobbyist tool or a clandestine consulting solution (2-user, 948 horsepower 3000s would do nicely for consultants). Not the destiny for something built to carry MPE over the bridges to the future, however.
