The IBM® Tivoli® Directory sever provides a tool named idsperftune (the Performance Tuning tool) that enables administrators to achieve higher directory server performance by tuning directory caches, DB2® buffer pools, and DB2 parameters. The idsperftune tool must be run against a directory server instance with RDBM configured. If the tool is run against a proxy server instance, the tool will provide an appropriate error message and will exit.
The idsperftune tool runs based on the inputs it received from an administrator. If the inputs are not provided by the administrator, then the default values are considered. The inputs from the administrator are provided to the tool using the property file, perftune_input.conf. For information about configuring and running the Performance Tuning Tool using the Configuration Tool, see the IBM Tivoli Directory Server Version 6.3 Installation and Configuration Guide.
The idsperftune tool works in two modes: basic and advanced.
