Re: Relocating LOB segment

Without knowing your version it is hard to give you correct information but I will give you a couple of thoughts that might help based on tools and methods I have used.

If you are on 11.2 and use SecureFiles then you can export with parallel. I have used this a few times but it does require the lob to already be stored as secure files. See metalink doc 1467662.1 for details.

Another alternative is to use DBMS_REDEFINITION. If you haven't used this tool before it is awesome. You can move the table behind the scenes while allowing transactions to continue (captured via materialize views behind the scene). Once the initial table create and data load is done you can sync the changes, then build your indexes, keys, etc. and then run the finalize procedure.

Hope that helps.
