Hmm...

One option might be to monitor x$bh for blocks belonging to that object every ten minutes for a week. If it doesn't appear, the object can pretty conclusively be called "not in use".

Seema,

It is always better to include the OS and database versions to the post :)

Okay.. To answer your question.. If you are using Oracle9i you can find that
by querying V$OBJECT_USAGE after turning the monitoring option for the
index. If it is pre Oracle9i database there is no direct way of doing this.
