Note:
These views are populated only for tables with theMONITORING attribute. They are intended for statistics collection over a long period of time. For performance reasons, the Oracle Database does not populate these views immediately when the actual modifications occur. Run the FLUSH_DATABASE_MONITORING_INFO procedure in the DBMS_STATS PL/SQL package to populate these views with the latest information. The ANALYZE_ANY system privilege is required to run this procedure.| Column | Datatype | NULL | Description |
