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?
|CPUs||Cores||Sockets||Load Average Begin||Load Average End||%User||%System||%WIO||%Idle|
|%Total CPU||%Busy CPU||%DB time waiting for CPU (Resource Manager)|
