SCOPE
Automatic Workload Repository (AWR) Overview
Automatic Workload Repository (AWR) is a licensed feature that allows information to be recorded on a database for multiple purposes including detection and elimination of performance issues.
For a general overview of Performance Advisors and Manageability Features, see:
Document 276103.1 PERFORMANCE TUNING USING 10g ADVISORS AND MANAGEABILITY FEATURES
Assuming you have the appropriate licenses for AWR, you may gather and examine Automatic Workload Repository (AWR) reports for the system.
