Architecture
As shown in Figure 1, the Database Module consists of Oracle Servers having a primary database and a replicated secondary database managed from the Oracle Enterprise Manager (OEM) Console. The Oracle databases operate in replicated mode and applications and components normally send and receive data directly to and from the primary database.
Monitoring logs, alarms, and operational measurements, OEM login, and maintenance updates are done from the System Management Console.

Note: Nortel Networks recommends that you back up the database daily whether it is a redundant configuration or not. If there is no redundancy in the network, there is no replication process, so backup of the data is even more important.
