Overview of the Juniper Networks Database

Each C-series platform contains a Juniper Networks database. The database can store SRC data, SRC sample data, SRC configuration information, and a number of user profiles. You store subscriber data in another database. For information about configuring the SAE to access subscriber data, see the SRC-PE Network Guide, Chapter 2, Configuring the SAE with the SRC CLI.

You must enable the database for it to be operational on the system. After the database is operational, you can load sample data and perform other configuration activities that use this database.

When the C-series platform starts for the first time, you must enable the Juniper Networks database.You can operate this database as a standalone database or as a member of a community of Juniper Networks databases. Typically, you run the database in standalone mode only in testing environments. In standalone mode, the database does not communicate with other Juniper Networks databases; there is no data distribution and no redundancy. In community mode, databases distribute data changes among specified databases. When you have two or more C-series platforms, enable the Juniper Networks database to run in community mode, and assign a role to each database:

We recommend that you configure at least two databases to have a primary role.

Neighbors are Juniper Networks databases that receive data from another Juniper Networks database. When you configure a database to be a neighbor, you configure it as one of the following types:

We recommend that you configure at least two databases as primary neighbors.

When you configure neighbors for the databases, keep in mind the following guidelines:

To share processing load, you can configure SRC components, such as SRC-ACP, NIC, or SAE to use a specified database. In the local configuration for SRC components, you configure the URL of the directory.
