    • for detailed trace output to "2"

    • for full trace output to "3"

Switching off Tracing

  • Set the attribute TRACE-LEVEL in the broker attribute file to 0:


    Omit the TRACE-LEVEL attribute.

Deferred Tracing

It is not always convenient to run with TRACE-LEVEL defined, especially when higher trace levels are involved. Deferred tracing is triggered when a specific condition occurs, such as an ACI response code or a broker subtask abend. Such conditions cause the contents of the trace buffer to be written, showing trace information leading up the specified event. If the specified event does not occur, the Broker trace will contain only startup and shutdown information (equivalent to TRACE-LEVEL=0). Operating the trace in this mode requires the following additional attributes in the broker section of the attribute file. Values for TRBUFNUM and TRAP-ERROR are only examples.

Attribute Value Description
TRBUFNUM 3 Specifies the deferred trace buffer size = 3 * 64 K.
TRMODE WRAP Indicates trace is not written until an event occurs.
TRAP-ERROR 322 Assigns the event ACI response code 00780322 "PSI: UPDATE failed".

Dynamically Switching On or Off the EntireX Broker Trace

The following methods are available to switch on or off the EntireX Broker trace dynamically. You do not need to restart the broker for the changes to take effect.

    Run command utility ETBCMD with option -c TRACE-ON or - c TRACE-OFF. See ETBCMD.

  • Operator Command
    Issue an operator command. See TRACE.
