Top Activity shows only one CPU on 11g OEM

edited Jan 26, 2014 8:12PM in Database Administration (MOSC) 2 commentsAnswered
I have my development 11g (11.2.0.4.0) database run under Oracle Linux 6.3 (2.6.39-200.24.1.el6uek.x86_64) run in VMware Workstation VM.

I have allocated 4 x vCPUs to the VM and try monitoring performance with OEM. I have found that "CPU Cores" show on "Performance" tab is 4 but show as 1 on "Top Activity" page.

Do anybody know why is different?

Howdy, Stranger!
