The issue with a lot of these ways of monitoring indexes that are not used
is that there *could* be indexes in place that are soley there for something
like a year/month end report.. And you just might not catch that when
monitoring for a couple of months, drop the index, and get stung muchos when
your user fires off that all damaging report..

I do know there is a way to tell which indexes are accessed most recently by
query x$bh view. Is this what you want or something different? Sorry I
forgot
the initial posting of this issue.

Hi,
Why not to use otrace? Of cource, you may need some space to save
trace results, but you'll definitely get complete statistics.

We have a purchased application with over 1,300 indexes.
Can someone suggest a method to monitor the system to
determine which indexes are actively being used over time? I'm assuming
that some are old/not necessary and would like to save the overhead
of maintaining them.
