Howto migrate table into partitioning with LOB which has 7TB

in Database DataWarehousing (MOSC) 1 commentAnswered

Hello all,

we have normal table with 24mio. rows which has BLOB (in SECUREFILE) segment size 7TB. There are stored documents in XML. We want to switch this table into partitioning. I think that DBMS_REDEFINITION is not able to use because there are a lot of transactions per day and we don't have enough resources for UNDO.

Export/Import will take a lot of time. Export reads LOBs in serial session and it's not easy to do parallel.

Create a new empty partitioned table is not possible because customer needs data from old one.

Please do you have some idea howto solve it?
