Tanel/Original poster, Let me add one more issue about LOBs - My understanding is that rollback information for LOB changes is allocated from the LOB segment itself, and not from system UNDO or RBS. This is controlled by the PCTVERSION parameter - read more about it in the Concepts and SQL Reference manuals... The offshoot is that the space consumed by LOBs will increase when there are updates, depending on PCTVERSION.
