<div><p><span class="keyword">i5/OS™</span> PASE signals
|
|
and ILE signals are independent, so it is not possible to directly call a
|
|
handler for one signal type by raising the other type of signal.</p>
|
|
<p> You can use the <span class="keyword">i5/OS</span> PASE
|
|
Qp2SignalPase() API to post corresponding <span class="keyword">i5/OS</span> PASE
|
|
signals for any ILE signal that you receive. The QP2SHELL() program and the <span class="keyword">i5/OS</span> PASE <tt>fork()</tt> function
|
|
always set up handlers to map every ILE signal to a corresponding <span class="keyword">i5/OS</span> PASE signal.</p>
|
|
<p>The system automatically converts any <span class="keyword">i5/OS</span> exception
|
|
message sent to the program message queue of a call running the Qp2RunPase,
|
|
Qp2CallPase, or Qp2CallPase2 API to a corresponding <span class="keyword">i5/OS</span> PASE
|
|
signal. An <span class="keyword">i5/OS</span> PASE application
|
|
can therefore handle any <span class="keyword">i5/OS</span> exception
|
|
by handling the <span class="keyword">i5/OS</span> PASE
|
|
signal that the system converts it to.</p>
|
|
<p><span class="keyword">i5/OS</span> PASE provides
|
|
the following runtime functions that give you direct control over <span class="keyword">i5/OS</span> message handling:</p>
|
|
<ul><li>QMHSNDM</li>
|
|
<li>QMHSNDM1</li>
|
|
<li>QMHSNDPM</li>
|
|
<li>QMHSNDPM1</li>
|
|
<li>QMHSNDPM2</li>
|
|
<li>QMHRCVM</li>
|
|
<li>QMHRCVM1</li>
|
|
<li>QMHRCVPM</li>
|
|
<li>QMHRCVPM1</li>
|
|
<li>QMHRCVPM2</li>
|
|
</ul>
|
|
<p>See runtime functions for details on these functions.</p>
|
|
<div class="section"><h4 class="sectiontitle"><span class="keyword">i5/OS</span> message
|
|
support</h4><p><span class="keyword">i5/OS</span> provides
|
|
message support in a variety of contexts:</p>
|
|
<ul><li><strong>Job logs</strong>. Your job log contains any messages
|
|
issued by <span class="keyword">i5/OS</span> or your
|
|
application while it is running or being compiled. To look at a job log, type <kbd class="userinput">DSPJOBLOG</kbd> on
|
|
a command line. When the Display Job Log display screen appears, press F10,
|
|
followed by Shift + F6. These key combinations result in the Display All Messages
|
|
display screen being displayed and set to the most recent messages. To view
|
|
the details of any particular message, move the cursor to the message you
|
|
want to know more about and press F1.</li>
|
|
<li><strong>Work with active jobs</strong>. The Work with Active Jobs (WRKACTJOB) command
|
|
is useful for examining jobs and job stacks on the <span class="keyword">i5/OS</span>.</li>
