EXCI trace

The CICS® Transaction Gateway writes trace entries to the EXCI trace. Entries are in the CICS trace EXCI format.

The trace entries in a dump can be printed using standard z/OS® utilities.

To start an EXCI trace from the administration interface:

  1. Use the command 
    /D OMVS,A=ALL
    to display OMVS tasks.
  2. Find the CICS Transaction Gateway task, and note the ASID.
  3. Enter the DUMP command with a suitable comment. For example: 
    /DUMP COMM=(JGATE DUMP)
  4. Reply to the message with the ASID as follows:
    /R nn,ASID=aa,END
    where nn is the message number for the reply, and aa is the ASID.

See the System dumps section in the CICS Transaction Server for IBM® z/OS External Interfaces Guide for information on how to format the trace.
