That depends on the version and whether or not you specify UPDATE GLOBAL
INDEXES
With it "Oracle updates the global indexes on the table whose partition is
being exchanged. Global indexes on the table being exchanged remain
invalidated. If you specify the parallel_clause with the
update_global_index_clause, then Oracle parallelizes the index update, not
the exchange operation."

Thanks!
I had seen that command, but hadn't realized the implication of it!
I'm guessing that global indexes would still have to be brought up to date. Would that occur automatically as part of the exchange command, or would they have to be dropped and rebuilt afterwards?

definitely consider using alter table exchange to lessen impact.
if you're not familiar with it, it lets you swap data between a partition and a non-partitioned table. so you load the data into a "temp non-paritioned table", build the needed indexes and then do the exchange, and poof its there(ok pretty darn close to poof).
