I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

where does the data for the insert come from?
another table? another db? file? VALUES coded?
that part might be optimizable ...

anything else is about the target table:
does it have indexes ? yes => are they on a dedicated tablespace?
does it have INSERT triggers? yes => could they be deactivated for this big insert?
is the table partitioned?
and a couple of others.
