Home -> Community -> Mailing Lists -> Oracle-L -> RE: How many times has an index been used?
Hi,
Thanks for the replies to this question. Looks like I need >= 8i or trawl through the v$sqlarea either by spending money or writing a simple bit of pl/sql.
Thanks,
Steve Wilkes

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.
