CPU used by ORACLE

Question

Hi,
on 11G R2, on Win 2008.
In Windows we can not see background process (mmon, pmon, ...). Can we ?
How to see CPU used by Oracle background process ?
To day CPU was used at 90% by oracle.
I ran an AWR. But nothing about them in it. I wonder why Oracle was CPU intensive ?

Hi,
You can go to TASK Manager -> click on Resource Monitor and there can see different services/processes along with the amount of CPU they are consuming.
Hope this helps you.
