<h1 class="topictitle1">Specify default message handling for escape messages</h1>
|
||
|
|
<div><p>For each message you create that can be sent as an escape message,
|
||
|
|
you can set up a default message handling action to be used if the message,
|
||
|
|
when sent, is not handled any other way.</p>
|
||
|
|
<div class="section"> <p>Default message handling actions can consist of:</p>
|
||
|
|
<ul><li>Default program name. A program to be called that takes default action
|
||
|
|
to handle a message. The following parameters are passed to the default program:
|
||
|
|
<ul><li>Call message queue name. This parameter is a structure that consists of
|
||
|
|
many fields that identify where the system sent the message. </li>
|
||
|
|
<li>Message reference key (4 characters). The message reference key of the
|
||
|
|
escape message on the call message queue.</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>Dump list. A list of message data field numbers (the same numbers as the
|
||
|
|
substitution variables) that indicate which objects are to be dumped. <p>In
|
||
|
|
addition, you can dump any of the following:</p>
|
||
|
|
<ul><li>The data areas for the job</li>
|
||
|
|
<li>An internal machine data structure of a job</li>
|
||
|
|
<li>A job <p>Specifying a dump list for a job is equivalent to specifying
|
||
|
|
the <span class="cmdname">Display Job (DSPJOB)</span> command with the parameters <samp class="codeph">JOB(*)
|
||
|
|
OUTPUT(*PRINT)</samp>.</p>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p>If you do not specify default actions in message descriptions, you
|
||
|
|
will get a dump of the job (as if <samp class="codeph">DSPJOB JOB(*) OUTPUT(*PRINT)</samp> was
|
||
|
|
specified).</p>
|
||
|
|
<p>The default action specified in a message is taken only
|
||
|
|
after the message percolation action is completed without the escape message
|
||
|
|
being handled.</p>
