APAR status

  • Closed as program error.

Error description

  • If a client performs backup/archive/migration of a file while
    replication is running, replication can process the file twice
    for replication in the same session.
    This will result in a duplicate copy of the file being stored on
    the target server, which will not be managed by replication
    correctly, leading to increased occupancy.
    
    The impact will be that the target server consumes more storage
    than expected, the occupancy is higher, and the situation is not
    corrected with "FORCRECONCILE" option on "REPLICATE NODE"
    command.
    
    Additionally an error message like this may be seen on the
    source server :
