<h2>Tuning prestart job entries</h2>
|
||
|
|
|
||
|
|
<p>This document shows how to manage prestart jobs
|
||
|
|
to improve overall system performance.
|
||
|
|
Prestart jobs are jobs that start running before the work arrives.
|
||
|
|
A prestart job entry in a subsystem description tells the system
|
||
|
|
how many jobs to create and how to manage the prestart jobs.
|
||
|
|
What you tell the system affects how well the system works.
|
||
|
|
To get the best performance from your system,
|
||
|
|
you need to tell the system what workload to expect.
|
||
|

<p>The following sections contain the details:
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<blockquote>
|
||
|
|
<p><strong>Set the number of prestart jobs</strong><br>
|
||
|
|
This section uses the
|
||
|
|
<a href="../cl/dspactpj.htm">Display Active Prestart Jobs (DSPACTPJ)</a> command and the
|
||
|
|
<a href="../cl/chgpje.htm">Change Prestart Job Entry (CHGPJE)</a> command
|
||
|
|
to get the right number of jobs.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p><strong>Change job attributes for prestart jobs</strong><br>
|
||
|
|
This section creates a new job description and sets
|
||
|
|
the job message queue maximum size (JOBMSGQMX) and
|
||
|
|
job message queue full action (JOBMSGQFL) job attributes.
|
||
|
