[Version 5.0.1 and later]Tuning performance parameter index

Why and when to perform this task

To optimize your WebSphere Application Servers to their fullest extent, use the Performance Advisors in addition to the suggested procedures or parameters in the tuning parameter hot list and the tuning performance parameter index.

Performance Advisors

The Performance Advisors use the PMI data to suggest configuration changes to ORB service thread pools, Web container thread pools, connection pool size, persisted session size and time, prepared statement cache size, and session cache size. The Runtime Performance Advisor runs in the application server process, while the other advisor runs in the Tivoli Performance Viewer (TPV). For more information, see Using the Runtime Performance Advisor and Using the Performance Advisor in Tivoli Performance Viewer.

Tuning parameter hot list

Review the Tuning parameter hot list, which is a subset of the tuning parameter index. These hot parameters have an important impact on performance.

The tuning guide focuses on server tuning. If you want to tune your applications, see Performance: Resources for learning for more information about application tuning.

For your convenience, procedures for tuning parameters in other products, such as DB2, Web servers and operating systems are included. Because these products might change, consider these descriptions as suggestions.

Each WebSphere Application Server process has several parameters influencing application performance. You can use the WebSphere Application Server administrative console to configure and tune applications, Web containers, EJB containers, application servers and nodes in the administrative domain.

First, review the Tuning parameter hot list, which is a subset of the tuning parameter index. These parameters have an important impact on performance. Because these parameters are application dependent, the parameter settings for specific applications and environments can vary.

Each parameter in the tuning parameter index links to information that explains the parameter, provides reasons to adjust the parameter, how to view or set the parameter, as well as default and recommended values.
