Re: Difference in CPU% between WRKACTJOB & WRKSYSACT

Hi Richard,

Here is something I posted a while ago:

<post>
If you have Performance Tools loaded, also check WRKSYSACT. I prefer this to
wrkactjob in some cases. The reason being that WRKACTJOB runs at normal job
priority (20). When entering WRKSYSACT, the priority of your job changes to 1.
The difference can often be seen when you look at total CPU utilization on the
relevant screen. In the case of WRKACTJOB, it sometimes reflects as *****. This
is becuase the CPU utilization of the jobs are changing before you have actually
processed all of those in the active table. The CPU utilization is totalled on 
a sequential read through the active table!

I hope this makes sense. If not, I will elaborate.

Cheers.

Jan Megannon.
