Q

Installing Oracle9i on 32-bit AIX, continued

You previously answered the following question: "We are looking to upgrade from Oracle8i to 9i and our support reps are telling us that 9i is not available in 32-bit for AIX. Is this true?"

I've been working with 9i 32-bit AIX for quite some time now and it's also listed in the support/certification matrix provided by Oracle. I'm not sure where you got your info, but it sounds like you were given some bad info. The only way the info could be correct is if you are running a 64-bit AIX version... you can't run 32-bit Oracle on 64-bit AIX.

I, like the first questioner, am hoping to install Oracle 9.2 database on a 32-bit AIX machine. The CD says 64-bit. And all the documentation I've seen says 64-bit. I would be interested to know how you could be running the 9.2 database on AIX 32-bit. Oracle says its not certified. Does it work?
Someone else questioned my answer on this as well. Click to see my response.

Here's what the docs say:

32-bit/64-bit Information:
Starting with Oracle9i, the Server is always in 64-bit mode and ships with both a 32-bit and 64-bit Client Libraries. If the Server product is 64-bit then 64-bit hardware (processors) is required.

And, from Metalink Note 231901.1:
The kernel can be in either 32-bit mode or 64-bit mode. No patch is required to use Oracle 8.1.7 and or Oracle 9.2.0 on the former. Patch 2896876 is required if Oracle8i is going to be used on the latter. The Oracle 9.2.0 version for AIX 5L, on the other hand, does not use any such 32-bit kernel extensions, and therefore can run in either of the kernel modes. So, we can run Oracle 9.2.0 in either 32-bit or 64-bit kernel modes.

My experience has been in installing and using Oracle9i with an OS kernel in 32-bit mode.

Hope that helps.
