Re: Only half CPUs being fully utilized

Well -- the issue in case your DBAs and you were not aware stemmed from upgrading to or being on Oracle 10GR2 10.2.0.4. 10.2.0.5 likely fixed this issue.

The issue is with NUMA changes introduced with 10.2.0.4. We also had this issue when we moved to 10.2.0.4 release.

The following blog explains it all:
