The external CICS® interface writes trace data to two destinations: an internal trace table and an external MVS™ GTF data set. The internal trace table resides in the non-CICS MVS address space. Trace data is formatted and included in any dumps produced by the external CICS interface.
Trace entries are issued by the external CICS interface destined for the internal trace table, an MVS GTF data set, or both. They are listed in EXCI trace entry points.
To use GTF for external CICS interface tracing, GTF user tracing must be active, GTF must be started in the MVS image, and you must specify GTF=ON in the DFHXCOPT options table.
If you use GTF trace for both the CICS server region and the external CICS interface region, the trace entries are interleaved, which can help you with problem determination in the CICS-EXCI environment.
The external CICS interface does not support any form of auxiliary trace.
To format external CICS interface trace entries written to GTF, you can use the standard CICS DFHTR640 trace formatting routine.
To format external CICS interface trace entries you use the same FID and ID as for CICS (that is, FID=X'EF', and ID=X'F6C').
