The TRACE command with the DEST option can specify the destination of the trace output.
Release: TPX 5.4
Component: Z/OS 2.1 and above
The TRACE file is needed for TPX startup.
The TRACE FILE (DDNAME=XTRACE) is used when the TPXOPER "TRACE DESTINATION" (TR DEST) command is issued with external destination (EXT) option.
This overrides the Trace Destination parameter in the System Options Table (SMRT Debugging parameters).
Trace Destination - Specifies where the output from the TPX trace is written.
Valid values:
FMT - Write to TPX log
EXT - Write to XTRACE DD
INT - Write to in-memory table
To change the trace destination to the external trace (XTRACE) data set, issue the following command:
TR DEST,EXT
This should only be changed at the direction of TPX support.
For details see:TRACE Command to Specify a Trace Destination.
