The image fwsec_vm_003.gif shows how Oracle Database Firewall high availability works when you are using two Database Firewall Management Servers. The sequence is as follows:

- A pair of Oracle Database Firewall Management Servers, called a resilient pair, send data to and from a network switch. In the diagram, the Management Servers are together on a rectangle on the left.

- To the right of the Management Servers are a second resilient pair, two Oracle Database Firewalls. These Firewalls are also sending data to and from the network switch. In the diagram, the two Firewalls are on a rectangle to the right of the Management Servers.

- To the right of the Database Firewalls is the network switch. The network switch sends data to and from the protected database and to and from the database clients and applications.

- To the right of the network switch are the protected database and database clients and applications. In the diagram, the protected database is separate from the database clients and applications.
