WebSphere Application Server for z/OS







Abstract: WebSphere Application Server for z/OS Version 7 adds new configuration options and facilities for avoiding timeout-related abends. These enhancements include:

o Ability to "nudge" a timed-out request to completion without abending the servant region
o Stalled thread threshold to avoid abending a servant until a specific number of problem requests is reached
o CPU timeout option to prevent a runaway request from consuming excessive resources
o DISPLAY,THREADS command for information about server activity and for identifying long running requests
o Dispatch Progress Monitor (DPM) to gather documentation about a request that runs longer than expected.

In this IBM White Paper, we look at how you can make the best use of the new options in your environment.
