Re: i5/OS 32 or 64-bit ?

I gotta admit, I was stumped today. Yeah, sure, common occurrence, but
this was in an area I thought I understood. I went to download MySQL
for i5/OS today and it offered me two choices: SAVF for 32-bit and SAVF
for 64-bit POWER systems (it also offered TAR downloads for each).

And that made me sit back. I was under the impression that we've been
running 64-bit machines forever. But we have a 32-bit JVM. My head hurts!

So, is PASE 32-bit or 64-bit? Or both? And why two versions of MySQL?

Presumably out of compatibility reasons.

Remember, the whole PHP/MySQL stuff isn't really an i application, it
just runs in PASE. And that means that it works like the rest of the
world - porting a application from 32bit to 64bit requires a
recompile.

PASE works with 32bit and 64bit AIX binaries. I think the reason why
both 32bit and 64bit binaries are being offered is the fact that it
may aid compatibility with certain 3rd party PHP extensions, but
that's just a guess.
