Re: best way to limit a job

I agree with others that it would be better to assign a low priority to the job, then let the system allocate CPU, even if it consumes a much greater percent than other jobs. If you want to play tricks, you could add sleep() to the program; Chuck mentioned that. Other tricks would be to assign a time slice of 1 millisecond to the subsystem class, 1 max active threads in the subsystem. Constraining subsystem memory would probably work, but a bad idea; the only work getting done might be page-in, page-out.

Subject: best way to limit a job

I'm looking for the best and simplest way to limit how much of the system a
particular job will take.  Ideally, we would be able to configure a job so
that it won't take more than x% of the CPU (as seen on a WRKACTJOB display).
We've tried using *CLS objects, defining Run Priority and Time slice
seconds, but it doesn't seem to limit the job.  It still takes as much of
the CPU as it wants.

Suggestions?
