Re: Help: ias 9i on Linux

I'm running Oracle 8i (8.1.6) and Oracle Application Server 4.0.8.1 (IAS 9i's predesessor) on Red Hat 6.2 on a 866Mhz PIII with 256Mb RAM and three 10K 18Gb U160 SCSI drives. Although I haven't gone to IAS 9i yet (going to soon), to my understanding there is not a huge difference between the releases. Half your battle is already over in that you're using RH 6.2 and not 7. The install is rather straight forward; I didn't have any problems with it at all. The hardest part is deciphering Oracle's confusing, poorly written install doc. You didn't mention installing an Oracle database on the box - just IAS... if you want a database too I'd suggest installing it first, then IAS. IAS itself is really just a glorified webserver.

Contrary to what the doc says, you don't have to mess with any Linux kernel params. I did roll my own kernel to get rid of bloat, but I didn't do anything to the shared memory parameters. Oracle should work OK with a canned 6.2 kernel. You might want to tweak it some later if it goes beyond the demo stage.

256Mb of RAM is plenty for now. I'm running a 70 Mb SGA, and that seems to leave plenty of room for the 140 or so processes that the Application Server spins off.

Performance is excellent. I've written a couple of dynamic websites entirely in PL/SQL, and the OAS serves them up so fast you'd swear they were static pages.
