Reply with quote

Hi,

I submitted a job over 2 hours ago and the job is not getting any CPU time.

The machine is quiet, as it is currently outwith business hours, and should run quite quickly.

Is there anything I can do to try and speed it up?

Thanks

Oh, crud, you want somebody outside of your 'establishment' to diagnose your system?
More information, "the job is not getting any CPU time" is not very diagnostic....

This is definitely something only someone at your site can help you with. If the job you submitted is running as WLM discretionary work, and there is something eating up the CPU (CICS, DB2, IMS, TSO, ...) then your job may not get any CPU time for quite a while. But only your site support group knows the WLM policies established at your site and only they can tell you for sure why your job is not getting any CPU time.

Hello,

Suggest there are 2 quickly determined possibilities:

1. Something else is using all of the cpu cycles (as Robert mentioned).

2. Your job is waiting on "something" (though usually a timeout will happen in less than 2 hours). Depending on rules set for your system, your process might be waiting a long time for a volume to be mounted, for some other process to release some held resource, or the recall of something migrated that has been delayed for some reason.

These can only be determined by having someone look at your system and determine . . .

HSM Dataset recall is a possibility.

But, as Dick said, it sounds like the job is "waiting" on something.

What that "something" is, then you or a Tech support person will have to determine this....

have you bothered to look at the jes message for the job?

as everyone has said, 5 will get you 10,
job is waiting on a dataset that you are probably in.

If you are lucky and have RMF Performance Management tool available from IBM - you can interactively Monitor the jobs otherwise JESMSGLG is the only hope, especially if you don't want to touch base with your support!
