Tuning on z/OS

One of the goals of the WebSphere Application Server for z/OS programming model and runtime environment is to significantly simplify the work required for application developers to write and deploy applications. WebSphere Application Server for z/OS can help to relieve the application programmer of many of the plumbing tasks involved in developing applications. For example, application code in WebSphere Application Server for z/OS does not concern itself directly with remote communication, it locates objects which might be local or remote, and drives methods. As a result, there is no direct use of socket calls or TCP/IP programming in a WebSphere Application Server for z/OS application.

Separating application development tasks from determining where to run the application is one aspect of relieving plumbing tasks. Other aspects to consider include assistance with data calls for multiple types of beans, assistance with user authentication, and threading.

Removing tuning work from the application programmer does not mean that the work is complete. There might also be tuning work for database administrators, network administrators, security administrators, and performance analysts.

Use the following topics to tune your z/OS operating system to optimize WebSphere Application Server performance.
