Re: QZDASOINIT prestart job tuning



fixed

Agreed. I was just making the point that having a pre-start job there
waiting would be even more important if you did this - I wasn't
recommending it one way or the other.

I think setting the uses to 1 is going ti have an impact on overall system
CPU use. I think initial job startup is one of the more resource intensive
tasks.

Hi Chris

I've changed the initial number of jobs in the past, and seen other
customers do this as well, in order to get the preferred number of jobs
activated as part of starting the subsystem. At one customer it was set to
3,000 but I bet there are others out there with significantly higher
settings.

I'd set the number of jobs at around 750-800 maybe even a little higher
in your case (say 850), particularly if you are going to change the maximum
number of uses to 1. In that case you would want a job available for new
connections as they connect rather than having them delayed while a job
starts up.

Has anyone made changes to the QUSRWRK subsystem for the QZDASOINIT
prestart job?

I am looking at the ramification of changes the maximum number of uses
to
1 so they recycle after every connection. Also changing the initial
number of jobs and threshold. Even the additional number of jobs.

We have what I assume is the default:
Job . . . . . . . . . . . . . . . . . . . . . . : QZDASOINIT
Job description . . . . . . . . . . . . . . . . : *USRPRF
Library . . . . . . . . . . . . . . . . . . . :
Start jobs . . . . . . . . . . . . . . . . . . . : *YES
Initial number of jobs . . . . . . . . . . . . . : 1
Threshold . . . . . . . . . . . . . . . . . . . : 1
Additional number of jobs . . . . . . . . . . . : 2
Maximum number of jobs . . . . . . . . . . . . . : *NOMAX
Maximum number of uses . . . . . . . . . . . . . : 200
Wait for job . . . . . . . . . . . . . . . . . . : *YES

We currently have 747 running with a peak of 806 and 746 in use. Peak
usage is 805. Any suggestions on what I should set the values at?
