    ****************************************************************
    CSQMCLS2 does not handle condition DB2_NOT_AVAILBLE and takes a
    default action for unexpected errors generating abend
    5C6-00D40017.
    
    After the abend the shared dynamic queue is left locked
    returning MQRC 2042 MQRC_OBJECT_IN_USE to MQOPEN calls.
    

Problem conclusion

  • MQCLOSE with options MQCO_DELETE and MQCO_DELETE_PURGE will
    receive reason code MQRC_DB2_NOT_AVAILABLE (2342) when closing a
    shared dynamic queue while DB2 is not available.
    
    The shared dynamic queue can be opened and closed and after
    DB2 is available it can be deleted.
