Administration Guide Configuring database mirroring Configuring database mirroring You can use Microsoft® SQL Server® 2005 or 2008 database mirroring to configure the BlackBerry® Configuration Database for high availability. The BlackBerry Configuration Database only supports high safety with automatic failover (synchronous) operating mode for database mirroring. For more information, visit http://msdn2.microsoft.com/en-us/library/ms175059(SQL.90).aspx. Stop the BlackBerry Enterprise Server instances To maintain database integrity, you must prevent all services that use the BlackBerry® Configuration Database from connecting to the databases while you configure replication. 1. On the computers that host the BlackBerry® Enterprise Server components, in the Windows® Services, stop all of the BlackBerry Enterprise Server services in the following order: • BlackBerry Administration Service services • BlackBerry Mail Store Service • BlackBerry Instant Messaging Connector • BlackBerry MDS Connection Service • BlackBerry Dispatcher • BlackBerry Attachment Service • BlackBerry Controller • all of the remaining BlackBerry Enterprise Server services that connect to the BlackBerry Configuration Database 2. Repeat step 1 for each BlackBerry Enterprise Server component that connects to the BlackBerry Configuration Database. Configure database mirroring for the BlackBerry Configuration Database For more information about database mirroring, visit http://msdn2.microsoft.com/en-us/library/ms175059(SQL. 90).aspx. 1. In the Microsoft® SQL Server® Management Studio, change the Recovery Model property for the principal database to Full. 2. Change the Backup type option to Full and back up the principal database. 3. Copy the backup files to the database server that you want to have host the mirror database. 4. On the database server that will host the mirror database, restore the database. If you did not perform a full backup, specify the NO RECOVERY option. 5. On the principal database, in the Database Properties window, on the Mirroring page, run the Configure Security wizard. 6. Start the mirroring process. 109
