<h1 class="topictitle1">Close considerations for files shared in a job or activation group</h1>
|

|
|
<div><p>Listed here are the considerations for closing a database file
|
||
|
|
that is shared in the same job or activation group.</p>
|
||
|
|
<div class="p"><ul><li>The complete processing of a close operation (including releasing file,
|
||
|
|
member, and record locks; forcing changes to auxiliary storage; and destroying
|
||
|
|
the open data path) is done only when the last program to open the shared
|
||
|
|
open data path closes it.</li>
|
||
|
|
<li>If the file was opened with the Open Database File (OPNDBF) or the Open
|
||
|
|
Query File (OPNQRYF) command, use the Close File (CLOF) command to close the
|
||
|
|
file. The Reclaim Resources (RCLRSC) command can also be used to close a file
|
||
|
|
opened by the OPNQRYF command when one of the following parameters is specified: <ul><li>OPNSCOPE(*ACTGRPDFN), and the open is requested from the default activation
|
||
|
|
group.</li>
|
||
|
|
<li>TYPE(*NORMAL)</li>
|
||
|
|
</ul>
|
||
|
|
If one of the following parameters is specified, the file remains open
|
||
|
|
even if the Reclaim Resources (RCLRSC) command is run: <ul><li>OPNSCOPE(*ACTGRPDFN), and the open is requested from an activation group
|
||
|
|
other than the default.</li>
|
||
|
|
<li>OPNSCOPE(*ACTGRP)</li>
|
||
|
|
<li>OPNSCOPE(*JOB)</li>
|
||
|
|
<li>TYPE(*PERM)</li>
|
||
|
|
</ul>

|

<li class="ulchildlink"><strong><a href="rbafocloseex1.htm">Example 1: A single set of files with similar processing options</a></strong><br />
|
||
|
|
In this example, the user signs on and most of the programs that are used process the same set of files.</li>
|
||
|
|
<li class="ulchildlink"><strong><a href="rbafocloseex2.htm">Example 2: Multiple sets of files with similar processing options</a></strong><br />
|
||
|
|
In this example, different files are used for each application. The user normally works with one application for a considerable length of time before selecting a new application.</li>

||
|
|
<li class="ulchildlink"><strong><a href="rbafocloseex3.htm">Example 3: A single set of files with different processing requirements</a></strong><br />

This example shows the methods that can be used if some programs need read-only file processing and others need some or all of the options (input/update/add/delete).</li>
