The performance tuning tool

Edit online

You can use the idsperftune tool to tune directory caches, DB2® buffer pools, and DB2 parameters to improve the directory server performance.

The idsperftune tool (the performance tuning tool) is available in IBM® Security Verify Directory, version 6.2 and later. You must run the idsperftune tool against a directory server instance that is configured with DB2 database. If the tool is run against a proxy server instance, the tool generates an appropriate error message and exits.

You must provide inputs to the idsperftune tool to tune the directory server. To provide inputs to the idsperftune tool, you must update the perftune_input.conf property file by using the administrator credentials. If the inputs are not provided, then the default values are considered.

You can manually update the perftune_input.conf property file for a directory server instance at the following location:

AIX® and Linux™: instance_home/idsslapd-instance_name/etc
Windows™: drive\idsslapd-instance_name\etc

You can also find the installed version of perftune_input.conf file (for reference only) at the following location:

AIX: The default location for the perftune_input.conf file is /opt/IBM/ldap/V10.0.2/etc/.
Linux: The default location for the perftune_input.conf file is /opt/ibm/ldap/V10.0.2/etc/.
Windows: The default location for the perftune_input.conf file is C:\Program Files\IBM\ldap\V10.0.2\etc.

For information about the performance tuning tool, see the IBM Security Verify Directory Command Reference.

The idsperftune tool works in two modes: basic and advanced.
