Administration Guide Configuring BlackBerry Configuration Database high availability • 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. • If you are configuring database mirroring, configure the database servers as follows: • Only use static port number 1433. • Verify that the SQL Server Browser is running. • Do not use named instances. • If you are configuring database mirroring, turn off the Named Pipes option in the Microsoft SQL Server Native Client on the computers that hosts the BlackBerry Enterprise Server instances. 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 126
