Look for the name of the MV in the OBJECT_NAME column of DBA_HIST_SQL_PLAN, which will give you a list of SQL_IDs, not people or users. However, you can then query DBA_HIST_ACTIVE_SESS_HISTORY for session information (including USER_ID, MODULE, ACTION, etc) based on those SQL_IDs. Just be aware that the AWR information is not an audit trail, but sampled data, so it is not perfect or definitive.

But it is way, WAY, *WAY* better than nothing... :-)

Happy hunting!

Subject: Mat View - used by?

Hello,I'm trying to determine if we can lengthen the time to refresh on aparticular Mat View in Is there a way to see (via SQL?) whatother code utilizes this Materialized View (like a "used by")? It iscurrently on a 1/48 (every half hour) refresh which seems excessive to me. The naming of the view would suggest that it is used in Discovererreporting.Thanks,Anthony--
