APAR status

  • Closed as program error.

Error description

  • While running, redistribute creates control files to keep track
    of the redistribute progress and know where to resume the
    redistribute in case of a failure.
    
    There exists a timing hole where a database partition can
    receive data but the control file isn't kept on disk. In case of
    a failure and a REDISTRIBUTE ABORT operation we can replay the
    data and end up with duplicate records.
    
    The problem is hard to hit and only encountered during a
    REDISTRIBUTE ABORT operation. Only the table being processed at
    the time of the redistribute failure is affected.
