<div class="section"><h4 class="sectiontitle">What can I do with this system value?</h4><p>Specifies
|
|
the maximum amount of time (in seconds) for application cleanup during the
|
|
immediate ending of a job. This is both a maximum cleanup time and a minimum
|
|
amount of time needed to conclude that the signal handling procedure (SIGTERM)
|
|
has encountered a problem. The signal handling procedure is set up by the
|
|
application in the job and indicates how to process the incoming signals.
|
|
Only jobs running applications that use signal handling procedures use this
|
|
system value.</p>
|
|
<p>When a job being ended has a signal handling procedure
|
|
for the asynchronous signal SIGTERM, the SIGTERM signal is generated for that
|
|
job. When the signal handling procedure for the SIGTERM signal is given control,
|
|
the procedure can take the appropriate actions to avoid undesirable results
|
|
such as application data that has been partially updated. If the SIGTERM signal
|
|
handler has not completed in the specified amount of time, the system ends
|
|
the job.</p>
|
|
<p>If a job is ended in an immediate manner, the maximum time
|
|
for the signal handler is specified by this system value. This system value's
|
|
time limit is used when ending one job, when ending all the jobs in a subsystem,
|
|
or when ending all jobs in all subsystems. After two minutes from the initial
|
|
end request, the system operator can use the End Job (ENDJOB) command with
|
|
OPTION(*IMMED) to override the QENDJOBLMT value and end individual jobs immediately.
|
|
Only use this command if a job is unable to perform its cleanup due to lock
|
|
or wait conditions.</p>
|
|
<p>In order to allow enough time for both application
|
|
cleanup and system end-of-job processing, you may need to adjust the Maximum
|
|
time for immediate shutdown (QPWRDWNLMT) system value in the Restart category
|
|
of system values. If you set this system value, <span class="uicontrol">Maximum time for
|
|
immediate end</span>, to a value greater than <span class="uicontrol">Maximum time
|
|
for immediate shut down</span>, a warning message will be displayed.
|
|
When a power down occurs, all jobs must end within the time frame specified
|
|
by the <span class="uicontrol">Maximum time for immediate shut down</span> system
|
|
value in order for the power down to complete in a controlled manner.</p>
|
|
<p>Possible
|
|
values are from 30 to 3600 seconds (1 hour).</p>
