Dear Gurus,
Our system info:
ECC6.0 + Oracle 11.2.0.3 + AIX5.3 64bit
IBM P561 16CPU(32 Cores), 64GB RAM
We implemented Oracle advanced Compression Option (ACO) in our PRD DB at 05/05/2014.
After that , we found the average DB CPU utilizatoin is more that 70% all day. It's very abnormal!
Ues topas to check and can found that every active process alwasys costs about 10% CPU Utilization.
There is no specail process costs remarkable DB CPU Utilization. Please see the screenshot attached.
Use the below command, can see:
$ ps -ef | grep ora | wc -l | grep -v grep
376
Dose anyone know the issue?
Best Regards,
Jason
