CPU at 100% during oracle database backup

We are facing the issue of high CPU usage (reaches 100%) on the net-backup version 7.5.0.7, and due to that major backups are failing. First step: I have changed twice the /opt/SYMCOpsCenterServer...

    Hi,

    You didn't mention your server specs.

    You're running OpsCenter on your Master server, you should migrate to a dedicated server if you're facing performance issues.

    You're also running verbose logging, I don't figures on the impact on performance but one can assume having minimal logging will use less CPU than verbose logging, or atleast less memory.

OpsCenter is very CPU greedy.

The attachment show plenty of free memory and almost no "wait for I/O".

However CPU may be a issue:

load averages: 4.94, 1.83, 1.05
load averages: 6.37, 2.19, 1.17

How may cores do you have ?

The number of cores has a incluence of the interpretation of load average.
