The ENABLE TRACE command turns on session tracing. The command records internal gateway events.


Usage Notes  

Session tracing may contain some of these elements:

Note: Entries vary depending on the events and action taken.

  • Session number (if available)
  • Associated file description (if available)
  • Event
  • One or more of these events:
  • Assigned
  • Logged on
  • Logged off
  • Logoff forced (Teradata Database system killed session)
  • Logon failed (usually caused by invalid password)
  • Disconnected
  • Reassigned
  • Reconnected
  • Network address of the originating network-attached host
  • By default, tracing is disabled. After a Teradata Database system restart, tracing enabled earlier using the ENABLE TRACE command is continued.


    If tracing has been enabled and you do not use the DISABLE TRACE command to turn it off, the file system may become full.

    Before using the ENABLE TRACE command, you must select the host group from which the session is running using the SELECT HOST command. For information, see “SELECT HOST” on page 664.

    The trace file is a text file, which can be viewed by any tool that displays text. The trace information is the same trace information controlled by Gateway Control, and is logged to the same files.

    For additional information, see “DISABLE TRACE” on page 642. For information on the gateway log files, see Chapter 14: “Gateway Control (gtwcontrol).”


    To turn on session event tracing, type:
