Error description

  • If the rdqminit command is interrupted before completion then
    the subsequent rdqminit command and endmqm command fails with
    errors similar to the below:
    
    #rdqmint -m QM1  -d
    AMQ3817E: Replicated data subsystem call '/usr/sbin/crm -c
    rdqm.123649.qm1
    configure delete qm1_ip_with_rdqmx' failed with return code '1'.
    ERROR: object qmtsysa1_ip_with_rdqmx does not exist
    AMQ3874E: Failed to delete floating IP address from queue
    manager 'QM1'.
    
    # endmqm QM1
    AMQ3817E: Replicated data subsystem call '/usr/sbin/crm -c
    rdqm.#####.QM1
    configure delete qm1_with_ip' failed with return code '1'.
    ERROR: object qm1_with_ip does not exist

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All IBM MQ users who use Replication Data Queue Manager (RDQM)
    feature.
    
    
    Platforms affected:
    Linux on x86-64
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    When rdqmint command is run to remove floating IP resource it
    takes about 15 to 20 seconds to remove all the associated
    resource. If the command was interrupted by performing ctrl+c
    then it ended without cleaning up all the resources. Any
    subsequent attempts to remove or redefine the floating IP fail
    with error.  It also causes failures when the user tries to end
    the queue manager.
    

Problem conclusion

  • The code is modified to remove the orphaned resources if
    rdqminit command is rerun to delete the floating IP.
