RE: How many times has an index been used?

Hi All,

A cheaper solution to this is to use an AFTER LOGON trigger to set CREATE_STORED_OUTLINES to true. If the users have the CREATE ANY OUTLINE system privilege, you'll be able to see which indexes are being used in the DBA_OUTLINE_HINTS view.

There is also one called The Big Picture - from Bit by Bit www.bitbybit.co.uk - that scans all source, and SQL, and stores all execution plans in a BDE database. It then scans through all the exectution plans to determine whether an index is used or not.

It doesn't however tell you how many times the index has *actually* been used..

There is commercial software for determining this.

www.teleran.com
www.pinecone.com

Both rather spendy.
