Error description

  • ABEND5C6-00E70032 in CSQXADPO+03BC0 occurred when
    starting a channel while the CHIN is being stopped due to a
    STOP QMGR MODE(FORCE).
    
    The problem occurred because during the channel startup some
    TCP/IP requests were issued which ended with a return code
    indicating that TCP/IP was down.
    
    As the QMGR was running within a Queue Sharing Group, we tried
    to register the fact that the comms was no more available
    and CSQXADPO tried to update the XCF/DB2 datas to indicate
    the change.
    It called CSQXCSSF which returned back with a reason code
    00F5001C meaning CSQ5_DB2_UNAVAILABLE because the MSTR was
    already ended.
    This resulted in the ABEND5C6-00E70032 generated by CSQXADPO .

    ****************************************************************
    When an error occurs that prevents communication with the TCP/IP
    subsystem, the channel initiator will attempt to notify the
    other members of the QSG that it is no longer network-connected.
    
    The mechanism for communicating the failure relies on the queue
    manager. If the queue manager is also shutting down during this
    time then the attempt to notify others of the network failure
    will in itself fail. Because CSQXADPO is not expecting to
    receive this RC, it generates an 00E70032 abend to report
    the unexpected failure.
    

Problem conclusion

  • Processing has been amended to allow CSQXADPO to tolerate
    XCF notification failures without abending.
