In the outline report, monitor for outlines that either haven’t been used or haven’t been used recently, and review whether they are still pertinent to the database application. The outln_utl package is used to maintain outlines.

Monitoring Outline Hints

Outlines generate and use outline hints. The outline hints are viewed in the dba_outline_hints view. The report below demonstrates how to monitor the outline hints. A sample output from that report is shown below.
