Tracing on z/OS

There are different trace options that can be used for problem determination with IBM® MQ. Use this topic to understand the different options and how to control trace.

About this task

The trace facilities available with IBM MQ for z/OS® are:

  • The user parameter (or API) trace
  • The IBM internal trace used by the support center
  • The channel initiator trace
  • The line trace
Use the following links to find out how to collect and interpret the data produced by the user parameter trace, and describes how to produce the IBM internal trace for use by the IBM support center. There is also information about the other trace facilities that you can use with IBM MQ.
If trace data is not produced, check the following:
  • Was the GTF started correctly, specifying EIDs 5E9, 5EA, and 5EE on the USRP option?
  • Was the START TRACE(GLOBAL) command entered correctly, and were the relevant classes specified?
Other trace options available on z/OS are:
  • The channel initiator trace
  • The line trace
  • The CICS® adapter trace
  • System SSL trace
  • z/OS traces
