<h2 id="rzahyjou-rf">Directory Server and i5/OS journaling support</h2>
<p>Directory Server uses i5/OS database support to store directory information. Directory Server uses
commitment control to store directory entries in the database. This requires
i5/OS journaling support.</p>
<p>When the server or the LDIF import tool is started for the first time,
the following are built:</p>
<ul>
<li>A journal</li>
<li>A journal receiver</li>
<li>Any database tables needed initially</li></ul>
<p> The journal QSQJRN is built in the database library that you have configured.
The journal receiver QSQJRN0001 is initially created in the database library
that you have configured.</p>
<p>Your environment, directory size and structure, or save and restore strategy
might dictate some differences from the defaults, including how these objects
are managed and the size threshold used. You can change journaling command
parameters if necessary. LDAP journaling is set up by default to delete old
receivers. If the change log is configured and you want to keep old receivers,
execute the following from a command line:</p>
<pre class="xmp">CHGJRN JRN(QUSRDIRCL/QSQJRN) DLTRCV(*NO)</pre><p class="indatacontent">If the change log is configured, you can delete its old journal receivers
with the following command:</p>
<pre class="xmp">CHGJRN JRN(QUSRDIRCL/QSQJRN) DLTRCV(*YES)</pre>
<p>For information about journaling commands, see &quot;<a href="../rbam6/rbam6alphalist.htm">OS/400 commands</a>&quot; in the Programming topic.</p>
