Setting Initialization Parameters to Enable ADDM
Automatic database diagnostic monitoring is enabled by default and is controlled by the CONTROL_MANAGEMENT_PACK_ACCESS
and the STATISTICS_LEVEL
initialization parameters.
Set CONTROL_MANAGEMENT_PACK_ACCESS
to DIAGNOSTIC+TUNING
(default) or DIAGNOSTIC
to enable automatic database diagnostic monitoring. Setting CONTROL_MANAGEMENT_PACK_ACCESS
to NONE
disables many Oracle Database features, including ADDM, and is strongly discouraged.
Set STATISTICS_LEVEL
to TYPICAL
(default) or ALL
to enable automatic database diagnostic monitoring. Setting STATISTICS_LEVEL
to BASIC
disables many Oracle Database features, including ADDM, and is strongly discouraged.
