Just a word of caution - I haven't used datapump a lot, but the few
times I have used it I was very disappointed with its performance - it
took MUCH longer than good old exp/imp.  I don't have time to review my
notes right now and give you the specifics of exactly how I ran it with
my timings and all the bugs and tuning notes I found, but just be sure
to do some research first and beware that it's not necessarily true that
datapump speed > exp/imp speed so test it for your specific situation -
as usual, it depends.

Regards,
Brandon

Once you get to 10g on HP you can use datapump which is much faster
