Simply stated the JOBCPU% versus JOBCPUT% variables:
The metric JOBCPUT% does not divide by the number of processors.
If you have two processors, that would be a total of 200%.
To set a CPU threshold of 65 the calculation would be:
Two processors, a total of 200% so you would not divide by 2 to the threshold would be:
JOBCPUT% 130 or 2 x 65
JOBCPUT% Jobname Limit
JOBCPUT% Jobnam1 130
Per the doc that is in the SYSVIEW Parmlib CNM4BPRM member MVSTHRSH:
The limit value for JOBCPU% must be set based on the number of processors.
This is the percentage of the total CPU in use for all processors types.
The metric JOBCPUT% does not divide by the number of
Example: 4 processors - 100 / 4 = 25%
JOBCPU% = 25 would indicate that a job is
probably using 100% of one of the processors.
If the job has multiple TCBs, then the JOBCPU%
could be higher.
