|
|
<div><p>The fully qualified three-part name of the prestart job never changes
|
|
once a prestart job is started. The user name of the fully qualified three-part
|
|
job name always contains the user profile under which the prestart job is
|
|
started.</p>
|
|
<p>If a spool file is opened before a prestart job handles any work request,
|
|
the spool file is associated with the prestart job entry user profile. Otherwise,
|
|
it is associated with the current user profile of the job.</p>
|
|
<p>If the prestart job entry profile and the current user profile are different,
|
|
spooled files are spooled under a job with the job name being QPRTJOB and
|
|
the user name of the current user profile. (This is also true for prestart
|
|
job entries for server jobs.)</p>
|
|
<p>The class (<span class="parmname">CLS</span>) parameter on the prestart
|
|
job entry provides a way to control the performance characteristics of two
|
|
classes of prestart jobs per prestart job entry.</p>
