<div class="section"><h4 class="sectiontitle">What can I do with this system value?</h4><p>These two
|
|
system values specify the number of active and total jobs to allocate storage
|
|
for at restart.</p>
|
|
<p><strong>Active Jobs (QACTJOB)</strong></p>
|
|
<p>Specifies the initial
|
|
number of active jobs for which auxiliary storage is allocated when you restart
|
|
the system. An active job is a job that has started running but not ended.
|
|
This storage is in addition to the storage allocated using the total jobs
|
|
system value. Possible values are 1 through 32767.</p>
|
|
<p>You may determine
|
|
a new value to assign to active jobs. This value should be the estimated number
|
|
of jobs that are active on a typical heavy-use day. You can see the number
|
|
of active jobs on the system in iSeries Navigator by selecting <span class="uicontrol">Work
|
|
Management</span> and then selecting Active Jobs. The total number of
|
|
active jobs is shown in the status bar at the bottom of the iSeries Navigator
|
|
window. To ensure that this number is accurate, make sure the include criteria
|
|
specifies all jobs except system jobs. For more information about specifying
|
|
the include criteria, see the include section in the find a job topic. Select
|
|
to include everything except System in the Type field. System jobs do not
|
|
need to be considered when assigning a value to the active jobs at restart
|
|
system value.</p>
|
|
<p><strong>Total Jobs (QTOTJOB)</strong></p>
|
|
<p>Represents the minimum
|
|
number of jobs for which storage is allocated when you restart the system.
|
|
The number of jobs is the number supported by the system at any one time,
|
|
which includes the jobs on job queues, active jobs (including system jobs),
|
|
and jobs having output on output queues.Possible values are 1 through 32767.</p>
|
|
<p>If
|
|
this value is set so that the amount of storage required exceeds the amount
|
|
currently allocated, additional storage is allocated. If this value is set
|
|
so that the amount of storage required is less than the amount currently available,
|
|
no action is taken.</p>
|
|
<p>To find the number of total jobs in the system,
|
|
right-click your system in iSeries Navigator and select <span class="uicontrol">System Status</span>.
|
|
This number should usually be kept within reason as it is a factor in the
|
|
time to perform a restart and some internal searches. This may require periodic
|
|
removal of jobs that have only job logs. The CL Programming book has a discussion
|
|
of job logs and how to remove them for jobs that complete normally. As long
|
|
as a job has one or more spooled output files attached to the job, knowledge
|
|
of the job remains in the system and counts toward the display system status
|
|
value.</p>
|
|
<p>You may also use the Detach printer output after jobs have ended
|
|
(QSPLFACN) system value to control the reuse of job structures. This will
|
|
give you more control of the number of jobs being processed.</p>
|
|
<p>You should
|
|
set this value high enough so it will not normally be exceeded by the total
|
|
number of jobs.</p>
