Hi guys,
Following is an excerpt from an AWR report.
My questions are:
(1) What is the "%Total CPU" under the Instance CPU?
Obviously it isn't how much CPU is consumed by the instance because the "%User" is 10.7% and there is no way for the Instance CPU consumption to be more than %User.
(2) What is the "%Busy CPU"? How come it is more than 100?
Host CPU
CPUs | Cores | Sockets | Load Average Begin | Load Average End | %User | %System | %WIO | %Idle |
---|
2 | 2 | 1 | 0.30 | 1.23 | 10.7 | 5.6 | 5.3 | 77.7 |
Instance CPU
%Total CPU | %Busy CPU | %DB time waiting for CPU (Resource Manager) |

29.8 | 133.8 | 0.0 |
It's Oracle 12c R2 on Linux x86-64.
