Preparing the Database for Tuning
This section lists and describes the steps that must be performed before the database can be properly tuned.
To prepare the database for tuning:
-
Get feedback from users.
Determine the scope of the performance project and subsequent performance goals, and determine performance goals for the future. This process is key for future capacity planning.
-
Check the operating systems of all systems involved with user performance.
Check for hardware or operating system resources that are fully utilized. List any overused resources for possible later analysis. In addition, ensure that all hardware is functioning properly.
-
Ensure that the
STATISTICS_LEVEL
initialization parameter is set toTYPICAL
(default) orALL
to enable the automatic performance tuning features of Oracle Database, including AWR and ADDM. -
Ensure that the
CONTROL_MANAGEMENT_PACK_ACCESS
initialization parameter is set toDIAGNOSTIC+TUNING
(default) orDIAGNOSTIC
to enable ADDM.
