AWR report generator
The Automatic Workload Repository is a set of internal Oracle database dictionary tables and a special MMON background process that was introduced in Oracle10g .
Periodically, AWR creates a statistical copy (snapshot) and stores information in tables located in the SYSAUX tablespace. By default, the regular collection period is set to 60 minutes. This value can be reduced to 10 minutes if desired.
