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.
Regards

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