How to configure a new Oracle 9i system with fewer CPUs

We are in the process of migrating our 9i databases off an HP V 2500 box (16 CPUs, 64-bit) to an HP RP 8420 (6 CPUs, 64-bit). Other than upping the "parallel threads per CPU" parameter to compensate for the lesser amount of CPUs in the new box, what other performance tuning measures should we direct our attention to in an effort to have our decision support databases perform at their peak?

Most Oracle parameters that are related to the number of CPUs will be set automatically. You should review your SGA settings if the new server has a different amount of physical memory, but other than that, you may not want to change anything until you've observed performance under load. Your observations (traces, STATSPACK reports) will be your best basis for making changes.
