Each Oracle database instance maintains a set of virtual tables that record current database activity. These tables are called dynamic performance tables.
The dynamic performance tables collect data on internal disk structures and memory structures. Dynamic performance tables are continuously updated while the database is in use. Among them are tables that collect data on Oracle OLAP.
The names of the OLAP dynamic performance tables begin with
SYS user owns the dynamic performance tables. In addition, any user with the
SELECT CATALOG role can access the tables.
The system creates views from these tables and creates public synonyms for the views. The views are sometimes called fixed views because they cannot be altered or removed by the database administrator. The synonym names also begin with
V$AW. The views are also owned by
SYS, but the DBA can grant access to them to a wider range of users.
The following sample SQL*Plus session shows the list of OLAP system tables.
