Selecting the Invocation Method for the ATBTRACE STOP Request

To stop API tracing activity, you may use any of the invocation methods described in Methods of Invoking the ATBTRACE REXX Exec, regardless of the method you chose to start an API trace. Before issuing a STOP request, make sure you are aware of the programming environment and restrictions described in Programming Considerations.

In general, using the same method to both start and stop tracing is the easiest approach, but unusual circumstances might require mixing methods. For example, suppose a particular TP is not functioning correctly in your installation's production system. You might choose to issue the START and STOP requests in the TP profile JCL, so you can collect trace data each time the TP runs. If you find that, because multiple instances of the TP are running, tracing activity is impacting the performance of APPC/MVS work, you could issue the STOP request through TSO/E instead.
