MustGather: Read first for all WebSphere Application Server products
 Technote (FAQ)
 
Problem
MustGather documents aid in problem determination and save time resolving Problem Management Records (PMRs).

Collecting MustGather data early, even before opening the PMR, helps IBM® Support quickly determine if:
  1. Symptoms match known problems (rediscovery).
  2. There is a non-defect problem that can be identified and resolved.
  3. There is a defect that identifies a workaround to reduce severity.
  4. Locating root cause can speed development of a code fix.

Gathering general information

For WebSphere Application Server V5.0.2 or later, use the collector tool to capture general information for each host machine. If you are running a version previous to V5.0.2, you can also manually collect the general information.

Entering "Collector -summary" output into an electronically-opened PMR (ESR) eliminates waiting on the phone to provide general information to Level 1 support.


Gathering component specific information

For assistance in help identifying the component causing problems, visit the Troubleshooting Guide for WebSphere Application Server.

Otherwise, take a look at the components and the component descriptions in the table below. If one of the product components below matches your symptom or the part of the product with which you are experiencing problems, follow the instructions in the associated MustGather document:

Submitting information to IBM Support

After a PMR is open, you can submit diagnostic MustGather data to IBM.

If using ESR, update the PMR to indicate that data has been sent.


Collector Tool

If you are running WebSphere Application Server V5.0 or higher, use the collector tool to capture information for components specified in the table above.

Entering "Collector -summary" output into an electronically-opened PMR (ESR) eliminates waiting on the phone to provide general information to Level 1.


Manually gathering general information

For releases of WebSphere® Application Server previous to V5.0.2, manually gather the following information for each host machine:
  • Hostname
  • The product and version of the Web server, if one is installed
  • The application server or clone, if either are installed
  • The WebSphere Application Server version and edition
  • The installed interim fixes
  • Your operating system and version
  • The operating system patches or maintenance level
  • The number of CPUs that you have
  • The amount of RAM that you have
