What Is a Dynamic Performance View
What Is a Dynamic Performance View? - Oracle DBA FAQ - Oracle Basic Concepts
✍: FYIcenter.com
Oracle contains a set of underlying views that are maintained by the database server and accessible to the database administrator user SYS. These views are called dynamic performance views because they are continuously updated while a database is open and in use, and their contents relate primarily to performance. Although these views appear to be regular database tables, they are not. These views provide data on internal disk structures and memory structures. You can select from these views, but you can never update or alter them.
