+-- File name:   mon_topsql.sql (Daily TOP SQL reporting for Exadata)
+--
+-- Purpose:     This script can be used for getting an overview of your most
+--              time-consuming SQL statements along with important IO and execution
+--              count metrics needed for determining whether a query would
+--              benefit from Exadata Smart Scanning features.
+--
+-- Usage:       Run @mon_topsql.sql
+--
+--              There's a variable called "days" in the beggining of this script
+--              which controls how many days worth of history to show.
