The HP 3000 isn't the only Business Critical System that's weathering the winds of migration. Some companies are seeing the light at the end of their Unix tunnel and making the move onto an open source environment. Linux has been the choice for CASE, a maker of banking software which had a 3000-using customer base not so very long ago.
A recent chat on the mailing list devoted to the database Eloquence pointed to another HP-UX refugee. Rick Gilligan commented during a discussion about HP-UX future platforms that the company had dumped HP's Unix at the close of 2011. The applications made the move to Linux, where there was "Some minor amount of work in going to Linux on x86_64, to handle the [Big vs. Little] endian issues. Eloquence was the trivial part of the port to Linux on x86_64."
That's 64-bit Linux on Intel's Xeon lineup, usually presented to HP sites as a ProLiant server installation. Eloquence is a equal-opportunity database for 3000 migrators, operating on Linux, HP's Unix as well as Windows. HP's Unix, on the other hand, is locked into the bit-map Endian issues of Integrity/Itanium systems. HP-UX is Big-endian and the current Xeon hardware line is little-endian. That's where the Eloquence list chat began, when someone asked about a new Xeon-based BCS server for HP's Unix. Turns out there is no such thing, despite the hopes from HP's Unix market.
So in one sense, Eloquence will be supporting the new platform for HP-UX features -- because the database is already supported on Linux and Intel Xeon systems.
Christian Scott of Softvoyage, a software company that used Speedware to create a travel agency app for 3000s and then moved to other environments, said "I wouldn't expect to see HP-UX on Xeon." He pointed out an HP webpage that answers questions about Project Odyssey. "And HP was pretty clear to me that there is no port of HP-UX to Xeon in their long term strategy. HP-UX has a roadmap of 10 years, so you can read between the lines."
As for the features that HP will be moving from HP-UX to Linux, Gilligan is skeptical. "So what are these HP-UX features they would bring to Linux? And are they going to only be on Linux running on HP hardware? If so, it's still a proprietary environment. There's nothing from HP-UX which we lost when moving to Linux, except for perhaps the high price."
