Can you please let us know the correct script with clear usage …

I have been playing around with aveact.sql. I created a load, using a crude load script on my dual core cpu laptop.
I ran the load script on 3 different sessions concurrently. After a few minutes I ran the aveact.sql script and I got output as below:

The thing that is confusing me is the CPU measurement. How can it be so far above the #CPUs?
Enterprise manager is broken on my laptop so I can’t double check there.
I was wondering if you may have seen this before?

Response:
It means there is more demand for CPU than there is CPU available.
It’s like the run queue on UNIX.
Clearly shows that there is a bottleneck on CPU.
In 11g OEM you will see CPU time and WAIT for CPU time. Wait for CPU time is demand for CPU minus the actual CPU used. CPU used is measured with OS counters where as demand for CPU, at least below, is measured from ASH by counting sessions who are ready to run on the CPU.

Best Wishes
