Not much at all, you can use monitoring in Oracle 8i.

Since it only writes the changes every few hours, it has very monitor impact.

Wow, that's a nice feature. Any idea what the overhead is for this (not that we'll be moving to 9i for at least a year)?

Under 9i

MONITORING USAGE | NOMONITORING USAGE Use this clause to begin or end the collection of statistics on index usage. This clause is useful in determining whether an index is being used.

Specify MONITORING USAGE to begin statistics collection. Oracle first clears existing statistics on index and then begins to collect statistics on index usage. Statistics collection continues until a subsequent ALTER INDEX ... NOMONITORING USAGE statement is executed.

To terminate collection of statistics on index, specify NOMONITORING USAGE.
