Use the CICS Execution Diagnostic Facility

 

We can use the CICS execution diagnostic facility (CEDF) to monitor applications that use the CICS adapter. For details of how to use CEDF, see the CICS Application Programming Guide.

CEDF uses standard formatting to display MQI calls.

• Before the MQI call is executed:

  • CEDF displays the addresses of the call parameters

  • We can use the Working Storage key to verify or modify their contents

  • We can skip the call by overtyping the command with NOOP

• After the call has completed:

  • The results are returned in the program’s storage

  • The return code and reason code are displayed in the call parameter list

  • We can modify them before returning to the application program

See WebSphere MQ for z/OS Problem Determination Guide for examples of the output produced by this facility.
