APAR status

  • Closed as program error.

Error description

  • The rdqmdr command might revert DR queue manager to an earlier
    date i.e.  a state as at a date many days/weeks/months back when
    making QM that is currently in the secondary role into the
    primary role.
    

Local fix

  • By running the 'lvs' command as root, all logical volumes and
    RDQM snapshots are displayed. Manually remove any old snapshots
    by using the 'lvremove' command before running rdqmdr command.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users running rdqmdr command to change queue manager role from
    secondary to primary
    
    
    Platforms affected:
    Linux on x86-64
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    MQ RDQM DR queue manager resyncs data if the data between 2
    nodes is out of sync.
    A defect in MQ RDQM DR resync process might leave an orphaned
    queue manger shapshot.
    This snapshot will cause the queue manager to be restored to an
    old state when the QM that is currently in the secondary role is
    made into the primary role.
    

Problem conclusion

  • MQ code has been modified to prevent the DR queue manager being
    restored to on old state.
