Error description

  • Running with large number of LOADs with large amount of LOB
    data(about or more than 2-5 GB), then in a HADR standby (or
    analogous rollforward scenario), after the load copy image file
    is replayed/processed, some LOBA page may be written into wrong
    location in the tablespace, thus leading to data corruption.
    "large amount" is typically a few GBs, but unfortunately we
    cannot describe it more precisely, as it depends on tablespace
    extent size, and also whether we have lots of smaller LOBs vs
    fewer number of larger LOBs.
