<h1 class="topictitle1">Processing flow</h1>
|
||
<div><p>This topic shows the processing flow of the processing program.</p>
|
||
<p>The standard program is called from applications that must start again.
|
||
The application programs pass this parameter list to the standard program:</p>
|
||
<ul><li>Request code</li>
|
||
<li>Return code</li>
|
||
<li>Data structure name (the contents of the notify object)</li>
|
||
</ul>
|
||
<p>Request codes the following operations:</p>
|
||
<ul><li>R (Read) <p>Retrieves the last record added to the notify object
|
||
with the same key. The return code is set as:</p>
|
||
<dl><dt class="dlterm">0</dt>
|
||
<dd>No record is available (no start again required).</dd>
|
||
<dt class="dlterm">1</dt>
|
||
<dd>Record returned in the information field for starting again (start again
|
||
required).</dd>
|
||
</dl>
|
||
</li>
|
||
<li>WA (Write) <p>Writes a record to the file. This code can be used
|
||
if you use a notify object for your own purposes. For example, if the program
|
||
determines that the transaction needs to be started again, the program can
|
||
write a record to the notify object to simulate what the system will do if
|
||
a job or the system fails.</p>
|
||
</li>
|
||
<li>DE (Delete) <p>Deletes all records in the notify object with the
|
||
same key. The return code is set as:</p>
|
||
<dl><dt class="dlterm">0</dt>
|
||
<dd>No records exist to be deleted.</dd>
|
||
<dt class="dlterm">1</dt>
|
||
<dd>One or more records were deleted.</dd>
|
||
</dl>
|
||
</li>
|
||
<li>OE (Open) <p>The O request code is optional and is used to avoid
|
||
having to start the processing program each time it is called.</p>
|
||
</li>
|
||
<li>CA (Close) <p>After the open request code is used, using the close
|
||
request code ensures that the file is closed.</p>
|
||
</li>
|
||
<li>SA (Search) <p>Returns the last record for this user. The program
|
||
name is not used. This code can be used in an initial program to determine
|
||
whether starting again is required.</p>
|
||
</li>
