Review the WebSphere Application Server for z/OS configuration

WebSphere Application Server provides tunable settings for its major components to enable you to make adjustments to better match the runtime environment to the characteristics of your application.

Before you begin

Many applications can run successfully without any changes to the default values for these tuning parameters. Other applications might need changes, for example, a larger heap size, to achieve optimal performance.

About this task

Before you read a description of WebSphere Application Server 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.

Procedure

  1. Review the WebSphere for z/OS configuration. One simple way to do this is to look in your application control and server regions in SDSF.
  2. When each server starts, the runtime prints out the current configuration data in the joblog.
