Timeout condition resolutions

This topic gives an overview of how to resolve timeout conditions.

In such a complex environment as WebSphere Application Server for z/OS, timeouts might occur for many different reasons. Although you can alter timeout values, you should not do so until you understand why the timeout occurs. Depending on the timeout condition, you might be able to permanently fix the timeout condition by doing some system or application tuning. For example, if the diagnostic data indicates throughput problems, you can alter the number of server regions, the number of threads within each server region, or the use of replicated servers.

Generally speaking, increasing the timeout values should be your last resort, or only a temporary action taken to prevent multiple timeout-abend dumps from causing system performance problems. If you increase timeout values without properly diagnosing the timeout condition, the only results you might see are less frequent abends and dumps for the same timeout condition, or slower system or application performance.
