Hi list: Would you please check out this tool - DBspeed? http://www.dbspeed.com/index.html It provides hundreds of data mining queries to examine the performance data in Automatic Workload Repository (AWR) and Active Session History (ASH). A read-only database account can run all those queries. It also allows create and browse conventional Oracle AWR and ASH reports without logging to database servers.
