Error description

  • Customer received errors
    CSQX476E: CSQXRESP CHANNEL channel-name IS ACTIVE ON qmgr-name
    SHARED STATUS ENTRY FOUND
    CSQX599E: CSQXRESP CHANNEL channel-name ENDED ABNORMALLY,
    CONNECTION conn-id
    CHIN has ADOPTMCA=ALL and ADOPTCHK=ALL and rriAdoptSharedMCA is
    invoked to try and adopt the shared status entry. It compares
    the conname from the status entry with that of the sender trying
    to connect. However, the conname in the status entry is suffixed
    with a null, which causes the adoption checking to fail.
    

Local fix

  • Customer could circumvent this problem by specifying
    ADOPTCHK=QMNAME

    * PROBLEM DESCRIPTION: Message CSQX476E is issued when a       *
    *                      channel initiator tries to adopt a      *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When a receiver channel is active on a queue manager and that
    queue manager is terminated then the channel may be adopted by
    another queue manager in the queue sharing group. A comparison
    is done (by rriAdoptSharedMCA) of the connection name in the
    channel with the name in the shared status entry. However, the
    latter is null terminated and the comparison may fail.
    This means that the channel is not adopted and fails with
    the CSQX476E message.
    

Problem conclusion

  • CSQXRCSI has been fixed so that the comparison is done only up
    to the null terminator, allowing the adoption to succeed.
