APAR status

  • Closed as program error.

Error description

  • CICS is not correctly handling timeouts from MQ. All failures,
    including timeouts, are being treated as transport failures,
    resulting in the wrong SOAPFAULT text being returned to a
    client.

    * PROBLEM DESCRIPTION: Unhelpful message returned when MQ web  *
    *                      service request times out.              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    An application program issues an EXEC CICS INVOKE WEBSERVICE
    command when MQ is being used as the transport. The provider
    system does not respond within the timeout interval and DFHPITQ1
    receives a MQRC_NO_MSG_AVAILABLE response. The SOAPFAULT message
    returned states that an internal server error occurred. This is
    not very helpful in diagnosing what has happened.
    Additional Keywords: msgDFHPI0110 DFHPI0110 MQGET
    

Problem conclusion

  • DFHPITQ1 has been altered to check for a return code of
    MQRC_NO_MSG_AVAILABLE on an MQGET. If it is received,
    then a new container, DFHMQTIMEOUT, is added to the
    pipeline channel. DFHPITQ then checks for the presence of
    this container. If it is present, then pitg_reason is set to
    pitg_timed_out. This results in the correct timeout message
    being sent and a TIMEDOUT response is returned by the
    EXEC CICS INVOKE WEBSERVICE command.
