What is the significance of the TRACE dataset that is allocated during TPX installation using TPXTRFMT ?

Products

• TPX - Session Management

Issue/Introduction

The TRACE command with the DEST option can specify the destination of the trace output.

Environment

Release: TPX 5.4
Component: Z/OS 2.1 and above

Resolution

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.
