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.
