BlackBerry Configuration Database mirroring

The following diagram shows how you can configure the BlackBerry® Configuration Database with principal and mirror instances

for high availability. The BlackBerry Configuration Database supports an optional witness. The BlackBerry® Enterprise Server

connects to the principal BlackBerry Configuration Database directly, and can fail over to the mirror BlackBerry Configuration

Database if the principal BlackBerry Configuration Database stops responding.

The primary BlackBerry Enterprise Server connects to the principal BlackBerry Configuration Database and accesses data from

it. The name of the mirror BlackBerry Configuration Database is stored in the Windows® registry of the computers that hosts the

primary and standby BlackBerry Enterprise Server instances. The BlackBerry Enterprise Server instances do not connect to the

mirror BlackBerry Configuration Database until after the principal BlackBerry Configuration Database stops responding.

The primary BlackBerry Enterprise Server connects to the messaging server and processes the messaging data that it sends to

and receives from BlackBerry devices.

The standby BlackBerry Enterprise Server opens standby connections to the principal BlackBerry Configuration Database and

the messaging server.

Scenario: What happens after the principal BlackBerry Configuration Database stops

responding

If a principal BlackBerry® Configuration Database stops responding, the response of the primary BlackBerry® Enterprise

Server depends on whether it can connect to the mirror BlackBerry Configuration Database.
