<h3 id="rzahysetdbconn">Set database connections and cache settings</h3>
|
||
|
|
<p>To set the database connections and cache settings, do the following:</p>
|
||
|
|
<p></p>
|
||
|
|
<ol type="1">
|
||
|
|
<li>Expand the <span class="bold">Manage server properties</span> category
|
||
|
|
in the navigation area of the Web administration tool, then click the <span class="bold">Performance</span> tab in the right pane.</li>
|
||
|
|
<li>Specify the <span class="bold">Number of database connections</span>.
|
||
|
|
This sets the number of DB2 connections used by the server. The minimum number
|
||
|
|
you must specify is 4. The default setting is 15. If your LDAP server receives
|
||
|
|
a high volume of client requests or clients are receiving "connection refused"
|
||
|
|
errors, you might see better results by increasing the setting of the number
|
||
|
|
of connections made to DB2 by the server. The maximum number of connections
|
||
|
|
is determined by the setting on your DB2 database. While there are no server
|
||
|
|
limitations upon the number of connections you specify, each connection does
|
||
|
|
consume resources.</li>
|
||
|
|
<li>Specify the <span class="bold">Number of database connections for
|
||
|
|
replication</span>. This sets the number of DB2 connections used by the server
|
||
|
|
for replication. The minimum number you must specify is 1. The default setting
|
||
|
|
is 4.
|
||

|

<div class="notetitle" id="wq200">Note:</div>
|
||
|
|
<div class="notebody">The total number of connections specified for database
|
||
|
|
connections, including database connections for replication, cannot exceed
|
||
|
|
the number of connections set in your DB2 database.</div></li>
|
||
|
|
<li>Select <span class="bold">Cache ACL information</span> to use the
|
||
|
|
following ACL cache settings.</li>
|
||
|
|
<li>Specify the <span class="bold">Maximum number of elements in ACL
|
||
|
|
cache</span>. The default is 25 000.</li>
|
||
|
|
<li>Specify the <span class="bold">Maximum number of elements in entry
|
||
|
|
cache</span>. The default is 25 000.</li>
|
||
|
|
<li>Specify the <span class="bold">Maximum number of elements in search
|
||
|
|
filter cache</span>. The default is 25 000. The search filter cache
|
||
|
|
consists of actual queries on the requested attribute filters and resulting
|
||
|
|
entry identifiers that matched. On an update operation, all filter cache entries
|
||
|
|
are invalidated.</li>
|
||
|
|
<li>Specify the <span class="bold">Maximum number of elements from
|
||
|
|
a single search added to search filter cache</span>. If you select <span class="bold">Elements</span>, you must enter a number. The default is 100. Otherwise, select <span class="bold">Unlimited</span>. Search entries that match more entries
|
||
|
|
than the number specified here are not added to the search filter cache.</li>
|
||
|
|
<li>When you are finished, click <span class="bold">OK</span>.</li>
|
||
|
|
<li>If you are setting the number of database connections, restart the server
|
||
|
|
for the changes to take effect. If you were modifying only the cache settings,
|
||
|
|
the server does not need to be restarted.</li></ol><img src="deltaend.gif" alt="End of change" /><img src="deltaend.gif" alt="End of change" />
