Collect troubleshooting data for hangs, crashes, and out of memory errors problems with WebSphere Process Server
You are having a hang, crash, or out of memory error problem in WebSphere Process Server. You would like to know what documentation you must collect (MustGather) so that the WebSphere Process Server Support team can diagnose your problem. If you gather this documentation before contacting support it will expedite the troubleshooting process, and save you time.
Resolving the problem
Collect the MustGather information for problems with relationships in WebSphere Process Server. Gathering this information before calling IBM support helps in understanding the problem and saves time when analyzing the data. You can use ISA Lite to automate this process.
|IBM Support Assistant|
Note: When you use ISA Lite, also gather a detailed problem description, environment description, and other requested materials.

Refer to the document Certified supported software for WebSphere Process Server for hardware and software prerequisites
Stay current with your maintenance by referring to the document Recommended WebSphere Process Server Fixes.
- Tuning guidance:
Issues often times end up having solutions in Tuning and Performance. Check that your environment is properly tuned and best practices are followed. Note: IBM Support cannot provide assistance with tuning. Refer to the following Guide specific to your version of the product:
Review the Java Diagnostic Guide as an additional resource for memory tuning. This is also linked in each of the above guides.
Review the document Collecting troubleshooting data for performance issues for additional information about Performance.

What is the difference between this document and the WebSphere Process Server document Collecting troubleshooting data for performance issues ?
This document captures the diagnostic steps for abrupt system failures and outages. Performance focuses on scenarios where the system is typically working, however fails under large or specific load. Performance may also be related to response time goals or resource (CPU/memory) usage goals for a particular scenario or workload.
How do I... (Troubleshooting) Java™- related guided documentation is available to assist with troubleshooting.
There are various presentations for WebSphere Application Server, which are available through the WebSphere Technical Exchange, that cover diagnostic and analysis techniques.
