availability

 

You can configure BlackBerry Configuration Database high availability by configuring database mirroring. Database mirroring requires that you configure a principal BlackBerry Configuration Database instance and a mirror BlackBerry Configuration Database. The BlackBerry Enterprise Server and BlackBerry Enterprise Server components can connect to the principal BlackBerry Configuration Database, and, if the principal BlackBerry Configuration Database stops responding, they can connect to a mirror BlackBerry Configuration Database automatically.

If your organization's environment does not support database mirroring, you can configure transactional replication. When you configure transactional replication and the BlackBerry Configuration Database stops responding, you must connect the BlackBerry Enterprise Server and BlackBerry Enterprise Server components to the replicated BlackBerry Configuration Database manually.

Prerequisites: Configuring database mirroring or database replication of the BlackBerry Configuration Database

Install the same version and build of Microsoft SQL Server for the mirror or replicated database server that you installed for the principal database server.

Configure the database servers to permit access from remote computers.

Verify that the Microsoft SQL Server Agent uses a domain user account with the local administrative permissions set to the same permissions as the Windows account that runs the BlackBerry Enterprise Server services.

Verify that the domain user account has permissons on both database servers so that each Microsoft SQL Server Agent can access the shared replication folder.

Configure the database server that will host the mirror or replicated BlackBerry Configuration Database with the same permissions that you configured on the database server that hosts the prinicipal BlackBerry Configuration Database.

Verify that the DNS server is running.
