<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>

<div class="section"><h4 class="sectiontitle">Where can I get more information about this system value?</h4><p>To
learn more, go to the jobs system values overview topic. If you are looking
for a specific system value or category of system values, try using the system
value finder.</p>
