<div class="section"><h4 class="sectiontitle">What can I do with this system value?</h4><p>You may specify
|
|
the action to take when an input/output (I/O) error occurs for an interactive
|
|
job's workstation.</p>
|
|
<p>The device recovery action is not performed until
|
|
the next I/O operation is performed by the job. In a LAN or WAN environment,
|
|
this may allow one device to disconnect and another to connect, using the
|
|
same device description, before the next I/O operations for the job occurs.
|
|
The job may recover from the I/O error message and continue running to the
|
|
second device. To avoid this, a device recovery action of <span class="uicontrol">Disconnect
|
|
job, and return to previous request level after reconnecting</span> or
|
|
<span class="uicontrol">End the job and send message to QHST log</span> should be
|
|
specified. These device recovery actions are performed immediately when an
|
|
I/O error, such as a power off operation, occurs.</p>
|
|
<p>You may select from
|
|
the following options:</p>
|
|
<ul><li><span class="uicontrol">Send error message to user's application (*MSG)</span> <p>Sends
|
|
the I/O error message to the user's application program. The application program
|
|
performs error recovery.</p>
|
|
</li>
|
|
<li><span class="uicontrol">Disconnect job, and send message to user's application after
|
|
reconnecting (*DSCMSG)</span> <p>Disconnects the job. When the user signs
|
|
on again, an error message is sent to the application program.</p>
|
|
</li>
|
|
<li><span class="uicontrol">Disconnect job, and return to previous request level after
|
|
reconnecting (*DSCENDRQS)</span> <p>Disconnects the job. When the user
|
|
signs on again, a cancel request function is performed to return control of
|
|
the job back to the last request level.</p>
|
|
</li>
|
|
<li><span class="uicontrol">End the job and send message to QHST log (*ENDJOBNOLIST)</span> <p>Ends
|
|
the job. A message is sent to the QHST log indicating that the job ended because
|
|
of the device error. To minimize the performance impact of the ending job,
|
|
the job's priority is lowered by 10, the time slice is set to 100 milliseconds
|
|
and the purge attribute is set to yes.</p>
|
|
<p>Select <span class="uicontrol">Produce a job
|
|
log</span> (*ENDJOB), if you want the message sent to the job log and
|
|
the QHST log.</p>
|
|
