How to use dumps for problem determination

When solving problems with your WebSphere MQ for z/OS system, we can use dumps in two ways:

• To examine the way WebSphere MQ processes a request from an application program.

  To do this, you usually need to analyze the whole dump, including control blocks and the internal trace.

• To identify problems with WebSphere MQ for z/OS itself, under the direction of IBM support center personnel.

You will often find that the dump title provides sufficient information in the abend and reason codes to resolve the problem. We can see the dump title in the console log, or by using the z/OS command

DISPLAY DUMP,TITLE. The format of the dump title is explained in Analyzing the dump. WebSphere MQ for z/OS abend codes are discussed in WebSphere MQ for z/OS abends, and abend reason codes are documented in the WebSphere MQ for z/OS Messages and Codes manual.

If there is not enough information about your problem in the dump title, format the dump to display the other information contained in it.
