Configuring Large PeopleSoft Application Servers

Occasionally, I see very large PeopleSoft systems running on large proprietary Unix servers with many CPUs.  In an extreme case, I needed to configure application server domains with up to 14 PSAPPSRV processes per domain (each domain was on a virtual server with 8 CPU cores, co-resident with the Process Scheduler).

The first and most important point to make is don't have too many server processes.  If you run out of CPU or if you fully utilise all the physical memory and start to page memory from disk, then you have too many server processes.  It is better to queue on a Tuxedo queue rather than the CPU run queue, or disk queue during paging.
