Performance tuning and capacity planning

Icon: configuring The performance tuning and capacity planning topics contain information about tuning the directory server for better performance.

Directory server tuning general overview
You must tune IBM® Verify Directory and the associated DB2® database to obtain optimum server performance.
Directory server tuning
You must decide the tuning roadmap, tuning LDAP caches, and the effect of directory size on the performance of a directory server.
Tuning DB2 and LDAP caches
You can tune the DB2® database that is configured with a directory server instance to reduce the search and update time.
Tuning AIX operating system
You can tune operating system and its resources to improve the performance of a directory server instance that is running on the system.
Hardware tuning
To improve the update performance of a directory server, you must improve disk drive speed.
Tuning directory server features
You can configure and tune the features in IBM® Verify Directory based on your requirements. You can also monitor the directory server performance and decide whether you want use certain directory server feature or not.
Capacity planning
Before you install IBM® Verify Directory on a system, you must decide the hardware to use for setting up the existing capacity and scaling up when required.
An example workload description
To configure a directory server with optimal settings for performance improvements, you must identify the data type and workload of your LDAP environment.
TCP/IP settings
You can verify and update the TCP/IP parameter values if you observe timeout failures when you access a directory server.
System configurations
