I am running an export and I saw that my indexes still appear to
have been exported by expdp. Should I use exclude=index to speed up
the export? How else can I speed up an expdp using the exclude
Answer: Data Pump DOES NOT export indexes!
The expdp utility only exports the index definitions, a whole other
The index trees and index data are never exported.
Instead, at import time, the indexes are rebuilt from the DDL
statements that exist in the dmp file.
The exclude=indexes only tells data pump to exclude the index
The index definitions are quickly punched from the data dictionary
in under one second.
Using exclude=index will not make your export run longer, and you
will want the index definitions when you run the impdp utility![/b]
This book has
complete details on the export exclude options for expdp.

notes on improving export speed.
