Hi,

How to list all non used index in a schema & to remove the same? We have a list of index, which may be used or mayn't be used .. please tell me how to identify that?

Thanks,
thiyagu

ALTER INDEX ... MONITORING USAGE;

Then query V$OBJECT_USAGE.USED.

Further to add.It will tell the index is used or not.

But will not tell you whether you need it or not.

Thanks for your reply. Smile

so i have to alter all my index in order to moniter. But i have 1000+ index in the schema. Is there any other way to identify the index usage without altering the index. My client is asking for report that includes Index name & used or executed no of time. Razz

Thanks,
thiyagu
