Trace formatting

There are three possible destinations for CICS® trace entries:

Internal
To main storage in the CICS region
Auxiliary
To a BSAM data set managed by CICS
GTF
To the MVS™-defined destination for generalized trace facility (GTF) records.

This topic describes the code used to interpret and format CICS trace entries from all of these destinations when they are processed offline.

For more information about using traces in problem determination, see the CICS Trace Entries.

In this context, "formatting" is used to mean the overall process of producing a report, suitable for viewing or printing, from trace data in a dump or trace data set. "Interpretation" is the process of taking just the point ID and the data fields from a trace entry and producing a character string describing what the entry represents.

There are four environments for trace formatting:
