GTFTR

The GTFTR system initialization parameter specifies whether CICS® can use the z/OS® generalized trace facility (GTF) as a destination for trace data.

Defining GTFTR

You can define the GTFTR system initialization parameter in the following ways:

On the PARM parameter of the EXEC PGM=DFHSIP statement
In the SYSIN data set of the CICS start up job stream
Through the system console
In the DFHSIT macro

Values for GTFTR

Valid values for the GTFTR system initialization parameter are as follows:

GTFTR={OFF|ON}

This system initialization parameter controls whether any of the three types of CICS trace entry are written to GTF data sets. The three types are: CICS system trace (see the SYSTR system initialization parameter), user trace (see the USERTR system initialization parameter), and exception trace entries (which are always made and not controlled by a system initialization parameter).

OFF: OFF is the default value for GTFTR. CICS does not use GTF as a destination for CICS trace data.
ON: CICS uses GTF as a destination for CICS trace data. To use the GTF data sets for CICS trace data, you must have started GTF with the USR option, in addition to coding GTFTR=ON.
