Set database connections and cache settings

To set the database connections and cache settings, do the following:

1. Expand the Manage server properties category in the navigation area of the Web administration tool, then click the Performance tab in the right pane.
2. Specify the Number of database connections. 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.
3. Specify the Number of database connections for replication. 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.
   Note:
   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.
4. Select Cache ACL information to use the following ACL cache settings.
5. Specify the Maximum number of elements in ACL cache. The default is 25 000.
6. Specify the Maximum number of elements in entry cache. The default is 25 000.
7. Specify the Maximum number of elements in search filter cache. 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.
8. Specify the Maximum number of elements from a single search added to search filter cache. If you select Elements, you must enter a number. The default is 100. Otherwise, select Unlimited. Search entries that match more entries than the number specified here are not added to the search filter cache.
9. When you are finished, click OK.
10. 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.
