Description of the illustration testmaster_clone.png

The image is a diagram that shows, from left to right, a Production Database (Primary), a Clone/Test Master Database (Physical Standby), four RW Snapshots, and four Test Instance Snap databases (DB1, DB2, DB3, and DB4). The top of the image has two arrows. The first arrow, labeled Clone Oracle RMAN Duplicate, leads from the Production Database to the Test Master Database. The second arrow, labeled Snap, leads from the Test Master Database to the Test Instance Snap databases. Refresh the primary database to create a physical standby Test Master. Read Write (RW) snaps are created from the Test Master. Each RW snap is associated with a different Test Instance Snap (DB1, DB2, DB3, and DB4).
