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.
- If you turned on the automatic failover option for the BlackBerry Enterprise Server, use the BlackBerry Administration Service to change the failover type to Manual until you finish configuring database mirroring or database replication.
