Gateway trace file

The tfile parameter is the path name of the trace file where Gateway trace messages are written, if tracing is enabled.

Set the value to the path name of the trace file. If you specify a name without a path, the file is created in the <install_path>/bin. No trace is written if the CICS® Transaction Gateway does not have permission to write to the file you specify. The trace file is overwritten, not appended to, each time the CICS Transaction Gateway starts. Turning on the Gateway trace has a significant impact on performance.

You can use the ctgstart -tfile=pathname command to override the value of tfile. For more information, see Options on the ctgstart commandCommand reference.

This parameter is in the GATEWAY section of the configuration file.
