This figure shows a single primary database sending redo data to multiple physical standby databases. For each reader database, there is an arrow pointing up to a monitor to indicate that clients and applications are accessing the physical standby database for queries and reporting purposes. Every standby database is a reader database, and one of the standby databases is also labelled as being enabled as the target for a fast-start failover. Finally, a picture of a monitor is shown next to the primary database to indicate that updates are continuously being made to primary database.
This is the end of the figure description.
