OS/400 support?

We don't support OS/400 yet do we?

Never heard of it. Is it Unix-y? Do you have one available for testing?

It's IBM. Not terribly Unix-y. This link may prove helpful:

I think Justin is refering to the AS/400 operating system. I have never
heard of Postgres supporting this operating system.

Oops, should have been clearer.

OS/400 is the operating system on the IBM AS/400 series of midrange
computers:

http://search400.techtarget.com/sDefinition/0,,sid3_gci331973,00.html

IBM AS/400 page:
http://www-132.ibm.com/content/home/store_IBMPublicUSA/en_US/eServer/iSeries/

Not sure if it's Unix-y or not. Just had the question come through the
Advocacy site request form. Will see if anyone else has further info,
and then ask the requestor for further details if not.

:-)

Regards and best wishes,

Justin Clift

AFAIK it's not Unix-y *at* *all*. The best/only way to run PG on that
hardware without an immense porting effort would be to run Linux
alongside OS/400 in an LPAR (logical partition).

That page quoth

OS/400 and its related software has added support for:

The Portable Application Solutions Environment (PASE), which
supports a subset of the AIX environment so that Unix applications can
be ported and run on the AS/400

This suggests that our AIX port might work with little or no tweaking.
Or perhaps not; "subset" could cover a multitude of sins. But it'd be
worth trying.

That would be very wild if we could do that. Who volunteered? ;)

No, OS/400 is what replaced IBM System 34, System 36, and System 38.
(Apparently they jumped to 40, and then multiplied by 10 to suggest it
was 10x as good...)

It was based on the CMU "Hydra" project, which built an OS with a pretty
strong security kernel, with ties to the "orthogonal persistence"
notion.

By this point, they have created a POSIX-emulation environment so it can
pretend to be somewhat like a Unix, but underneath, it's a database
system for running RPG code. As such, it kind of starts as a DBMS.

Somehow, I'm not sure that PostgreSQL-on-OS/400 is likely to be more
than a curiosity.

It might be pretty simple given PASE support and a hardware/OS manual. The
problem is that first assumption: how many OS/400 users have PASE
implemented? I'd say, not many.

It says here:
http://www-919.ibm.com/developer/factory/pase/v5r2.html

that PASE is standard as of OS/400 V5R2. Anyone know how old that is?

Probably. But a lot of our ports are just curiosities, at least to them
as aren't running that particular OS. My feeling is that Postgres on
top of PASE might be reasonable to support; I doubt we'd want to mess
with a native port.

Hi guys,

Have passed on the info everyone provided about ways of getting
PostgreSQL working on the OS/400 on to the requestor. It would be
interesting to see if they go with it.

Thanks for the assistance... more stuff will keep on coming through of
course.

:-)

Regards and best wishes,
