We have an AIX 6.1 that was upgradded from TL4 to TL6.
after the upgrade we started to see Oracle issues that we used to have after CPU increase was done in the past and we had to increase oracle memory to fix the issue.
All Oracle support docs say that the error we had is due to increase in CPU_Count.
although our SA say that we did not do such thing.
Will the 6TL upgrade be the culprit (have changed the way the CPU,Cores or thredas seen by the OS or the app)?
