Re: WrkActJob percentages are way off



fixed

I hate to say it but this is much less sinister than that.
WRKACTJOB shows details for what it works with - for jobs.
But not everything that runs on system is a job. There are lots of SLIC
tasks - save/restore, asynchronous pagein/pageout, TCP/IP router, database
SMP support, performance statistics collection - to name just a few.
All these consume CPU - sometimes quite a lot.
But these are not jobs, so WRKACTJOB does *not* show them in details
section. But they *are* included in WRKACTJOB header, which is system
totals.
Bottom line - CFINT or not, you are about to see this effect every now and
then.

WRKSYSACT is indeed a way to see all things which use CPU on system - it is
not limited to jobs.
You can also look at performance data collected by Performance Monitor
and/or Collection Services (it depends on release).
This data will also include SLIC tasks as well as jobs.

CFINT rears its ugly head. If you run WRKSYSACT you'll see the missing
CPU cycles. CFINT is a "governor" that prevents you from using more
interactive "features" than you have paid for. See VERY many previous
posts on that.
