Tracing EntireX Components under z/VSE

This document provides trace information for the following components:


Tracing EntireX Broker

Start of instruction setTo switch on tracing

  • Set the attribute TRACE-LEVEL in the broker attribute file

    • for minimal trace output to "1"

    • for detailed trace output to "2"

    • for full trace output to "3"

    Example:

    TRACE-LEVEL=2

Start of instruction setTo switch off tracing

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

    TRACE-LEVEL=0

    Or:
    Omit the TRACE-LEVEL attribute.

Tracing Broker Stubs

The broker stubs provide an option for writing trace files. Trace output is only available for transport method TCP.

Start of instruction setTo switch on tracing for the broker stub

  • Before starting the client application, set the environment variable STUBLOG in your application job control or CICS startup:

    Trace
    Value
    Trace Level Description
    0 NONE No tracing.
    1 STANDARD Traces initialization, errors, and all ACI request/reply strings.
    2 ADVANCED Used primarily by system engineers, traces everything from level 1 and provides additional information - for example the Broker ACI control block - as well as transport information.
    3 SUPPORT This is full tracing through the stub, including detailed traces of control blocks, message information, etc.

    Example:

    //SETPARM STUBLOG=2

If the trace level is greater than 1, unencrypted contents of the send/receive buffers may be exposed in the trace.

Trace output is written to SYSOUT.

Remember to switch off tracing to prevent trace files from filling up your disk.

Start of instruction setTo switch off tracing for the broker stub

  • Set the environment variable STUBLOG to NONE or remove the SETPARM statement.

Activating Tracing for the RPC Server

Start of instruction setTo switch on tracing for the RPC server

  • Set the parameter TRACELEVEL in the configuration file RPCPARM in sublibrary EXP960. Example:

    TRACELEVEL=SUPPORT
