    How to check if an index created is being used by the application - Oracle 8.1.6

    Would appreciate if someone could help me to identify indexes which are being used by applications. My development team has created many many indexes and I am sure some of the indexes are not being used resulting in performance issues.

    Thanks

    Check the view v$object_usage. An Yes or a NO will indicate whether the index is being used.

    However if u want to know if a specific query of the application is using an index, you can EXPLAIN PLAN and see the output.

    Vipassana, the v$object_usage is included in the 9i, so we may have to rely on the Explain plan.

    You can search the queries for the related table from v$sql and then check the queries for the explain plan.
