Hi
We are in process on restructuring/reorganizing the database and find out that DBA before has created many indexes on tables and lot of them are not needed and we want to drop them.
How do we find index that are created on tables and yet are not used ?
Thanks

What version?
In 8i, the standard response is "use catio.sql", although I have had marginal results with catio. You can also periodically sample v$object_usage, but this method is only a sampling and not a complete view of what is being used over time. In short, there's no "Easy" way to do it in 8i.
In 9i, you can use index monitoring. See http://otn.oracle.com/docs/products/...8a.htm#2113145 for details.
