APAR status

  • Closed as program error.

Error description

  • Any attempt to run HA/DR commands or to start an HA/DR Queue
    Manager fails.
    
    The following error is seen:
    
    AMQ8249E: The operation could not be completed because another
    HA or DR operation is in progress.
    
    Although there are no other HA/DR commands currently running on
    the pair of appliances.

  • Restart the MQ appliance (shutdown reboot 0)
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Any users of the MQ Appliance in an HA, DR or HA/DR setup.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A coding error in the HA/DR of the appliance caused an internal
    lock to fail to be removed when HA/DR commands exited under
    certain error conditions.
    The presence of this lock blocked further HA/DR commands from
    executing.
    

Problem conclusion

  • The MQ Appliance HA/DR logic has been corrected such that the
    HA/DR commands release held locks when exiting.
