PERFORMANCE TUNING OVERVIEW

Tuning a WebSphere Portal environment involves tuning and configuring the various systems and components of the environment. This chapter discusses some general concepts and details the specifics of the configuration used in our measurement environments. These specifics entail:

￿Configuring the application server and the resources defined for that application server

￿Tuning the database(s) and database server

￿Tuning the directory server and its database

￿Tuning the web server and/or proxy server

￿Tuning the operating system and network

￿Tuning the WebSphere Portal services

When tuning your individual systems, it is important to begin with a baseline, monitor the performance metrics to determine if any parameters should be changed and, when a change is made, monitor the performance metrics to determine the effectiveness of the change.

In addition to the tuning changes we made in our measurement environments, there are some additional tuning options available which can improve performance in certain circumstances; these will be discussed in a separate section.
