Configure the BlackBerry Enterprise Solution tosupport database mirroring
When you configure the BlackBerry Enterprise Solution to support database mirroring, the BlackBerry Administration
Service adds a registry key to all of the computers that host BlackBerry Enterprise Server components in the BlackBerry
Domain and the registry key includes the name of the Microsoft SQL Server that hosts the mirror database. The BlackBerry
Administration Service also adds the name of the Microsoft SQL Server that hosts the mirror database to the BlackBerry
Configuration Database.
CAUTION: If you click Save all more than once but you do not restart the BlackBerry Enterprise Server services or the
computers that host the BlackBerry Enterprise Server components that the BlackBerry Administration Service specifies as
Updated, you should restart the BlackBerry Enterprise Server services or restart the computers for all of the BlackBerry
Enterprise Server components.
Before you begin: The database server that hosts the mirror database must be running.
1. In the BlackBerry Administration Service, on the Servers and components menu, go to BlackBerry Solution
Topology > BlackBerry Domain.
2. Click Edit domain.
3. In the Database mirroring turned on drop-down list, click Yes.
4. In the Mirroring database host field, type the name of the mirror database server.
5. Click Save all.
6. On the computers that host the BlackBerry Enterprise Server components that are specified as Updated in the
Server responses to mirroring data update table, restart the BlackBerry Enterprise Server services or restart the
computers that host the components.
7. On the computers that host the BlackBerry Enterprise Server components that are specified as No response. Please
save the data again to attempt to update this server, verify that the computers are running and connected to the
network and then resend the database mirroring parameters to the BlackBerry Enterprise Server components.
