<h4 id="rzahjerrcfgjob-ref">Considerations for jobs that can affect error recovery</h4>
|
||
|
|
<p>When a line or controller fails, and the application programs are notified,
|
||
|
|
often you must end those jobs that were running over the line and controller.
|
||
|
|
Those jobs must be started again after the communications resource is recovered.
|
||
|
|
Jobs ending (particularly abnormal job ending) should be considered from a
|
||
|
|
performance perspective as an extremely complex transaction. Use the following
|
||
|
|
links to help you recover from an abnormal job ending.</p>
|
||
|
|
<ul>
|
||
|
|
<li>Device recovery, see <a href="rzahjerrconcmnrcylmtin.htm#rzahjerr-concmnrcylmtin">Considerations for the CMNRCYLMT parameter that can affect error recovery</a></li>
|
||
|
|
<li>Prestart jobs, see <a href="rzahjerrwrkprejobsinsts.htm#rzahjerr-wrkprejobsinsts">Change prestart job entries that can affect APPC error recovery</a></li>
|
||
|
|
<li>Joblog generation, see <a href="rzahjerrwrkjoblogsinsts.htm#rzahjerr-wrkjoblogsinsts">Joblog considerations that can affect communications error recovery</a></li>
|
||
|
|
<li>Using the Change System Job (CHGSYSJOB) commands
|
||
|
|
<p>The CHGSYSJOB command
|
||
|
|
allows you to change the run priority of a system job. The following are system
|
||
|
|
jobs of interest for communications recovery:</p>
|
||
|
|
<ul>
|
||
|
|
<li>QCMNARB01 through QCMNARB99</li>
|
||
|
|
<li>QSYSCOMM1</li></ul>
|
||
|
|
<p>In general, these system jobs should be allowed to run at their
|
||
|
|
default, system-provided priority. However, if one of these jobs begins using
|
||
|
|
large amounts of CPU, and is affecting other work on the system, it is possible
|
||
|
|
to lower its priority. Note that this may result in queued-up work for that
|
||
|
|
job.</p></li>
|
||
|
|
<li>Device Wait Timeout
|
||
|
|
<p>The device wait (DEVWAIT) timeout is used to limit
|
||
|
|
the amount of time a subsystem waits for workstation input/output to complete.</p></li></ul>
