RE: Index question

In 9i and later you can
alter index owner.index_name monitoring usage;

According to both Tom Kyte and Steve Adams there's very little overhead.

Then query v$object_usage to see whether the indexes are being used.

You should leave it on at least a month in case of end of month batch
jobs.
