This is very wrong. The whole problem with bugs in exp/imp isn't that you can compare data - it's that you might hit the bug in the future when it is too late.
Especially in the recent past, where merely doing a point upgrade can break it, and you _have_ to do the upgrade to be supported.
Note also one of the bugs was in buffer size...
To the OP: if you use direct on imp, be sure you understand all
ramifications.
It can work well, but when something messes up (like someone
interrupting a big load), it can be all-nighter time.

:-) It's not like Oracle figures it out before customers get it!
