Running Oracle 11 on Linux on z.   Z/VM LPAR assigned 4 IFL's.

We have a linux guest that got really busy for about 10-15 minutes
nightly.   Oracle process.     Guest has 2 virtual CPU's defined.

1) Our Oracle DBA (consultant and I believe he is coming from an intel
world) says we need more CPU's.   I say no.   Who's right and why?

2) on another guest on the same LPAR, we have 4 CPU's defined just to run
Oracle (for PeopleSoft).  I've never seen the CPU's 250% (out of 400%).
Should we drop it down to 3 (The oracle DBA says no and wants more).

Thanks!
