[Version 5.0.1 and later]Tuning performance parameter index

Why and when to perform this task

[Version 5.0.1 and later]Tuning parameter index for z/OS

[Version 5.0.1 and later]Performance tuning for WebSphere for z/OS becomes a complex exercise because the nature of the runtime involves many different components of the operating system and middleware. Use the Tuning index for WebSphere Application Server for z/OS to find information and parameters for tuning the z/OS operating system, subsystems, the WebSphere for z/OS runtime environment, and some J2EE application tuning tips.

[Version 5.0.1 and later] Recommendation: Before you read a description of WebSphere for z/OS tuning guidelines, it is important to note that, no matter how well the middleware is tuned, it cannot make up for poorly designed and coded applications. Focusing on the application code can help improve performance. Often, poorly written or designed application code changes will make the most dramatic improvements to overall 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.

If you are a WebSphere Application Server Administrator or Systems programmer on z/OS, refer to Tuning index for WebSphere Application Server for z/OS for z/OS specific tuning tips.

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.
