Hi!
If you do incremental commits the batch will run slower or not at all
(ora -01555).
Have you checked how much redo your insert statement generates? You
might have missed something.
If you have indexes on the table you will have to set them unusable and
alter session set skip_unusable_indexes=true
Rebuild the indexes after the load with nologging.
Janne!
