Silly question, but do you see more than four in this job class at other times. It may be limited to four.

It concerns a WLM managed jobclass, which is filled by Control-M. Every now and then, we see e.g. 4 jobs running and an accumulating number of jobs in the input queue, up to more than 100, waiting for one or more hours. When one job ends, the next job starts, but the number of executing jobs remains 4. I have ruled out all obvious causes, such as a heavy loaded system, jobs not eligible to run on that system etc. etc. >From the Redbook "System Programmer's Guide to: Workload Manager" I found that >JES2 is only following WLM, it will start a job when WLM has started an >Initiator ("If there are no free initiators, jobs run wherever another job >finishes, or WLM starts new initiators."). The $DSRVCLASS,LONG displays the >number of initiators WLM has started for JES2 to use. So the number of running job is fully determined by WLM and I am trying to find out why WLM does not start more initiators. The first period of the jobs has a Response Goal of 30 seconds. Since this includes a job's Input Queue time and jobs were waiting for several hours in the input queue, this only should have been a reason to start extra Initiators. I have produced SMF record 99 subtype 6 and it displays a lot of information about the status of the Service Classes, like MPL-IN-TARGET and MPL-OUT-TARGET, but I have the feeling that this applies to swapping IN and OUT of already running tasks and does not say anything about jobs in the Input Queue. My question is: which metrics can tell me more about WLM's decisions to start Initiators, not start them or stop them? Thanks in advance. Kees. ******************************************************** For information, services and offers, please visit our web site: http://www.klm.com.
