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.
