Thanks Mark! But, I don't think our exadata DBA team will go for that in
production. Can you say very decentralized?
Thanks though!

Also, just a thought:
For the duration of this load, disable FORCE LOGGING, then re-enable it
when load completes, and catch up the standby with an RMAN Incremental
backup?

Hi Woody,
Yes it does avoid UNDO, because it extends the table above the high-water
mark and inserts the data into empty blocks. Empty block do not contain any
information that would need to be saved in the UNDO segments. That is the
principal benefit of doing /*+ APPEND */. You may want to try using
DBMS_PARALLEL_EXECUTE instead of the /*+ PARALLEL */ hint. My experiences
with DBMS_PARALLEL_EXECUTE are quite good.

Didn't realize that about APPEND avoiding undo even if FORCE LOGGING.
