Understanding System Views
There are several local (V$) global (GV$) system
        views you can query to retrieve metadata information about your database.
               
- 
                     The V$views contain data for the element to which your application is connected.
- 
                     The GV$views contain the contents of theV$view for every element of the database.
In addition, there are several views that you can query that are based on TimesTen built-in procedures. See System Tables and Views in Oracle TimesTen In-Memory Database System Tables and Views Reference.
