Installing a standby BlackBerry
Enterprise Server
To configure the BlackBerry Enterprise Server for high availability and disaster recovery, you install a standby BlackBerry
Enterprise Server
on a separate computer from your organization's primary BlackBerry Enterprise Server. During the
installation process, you assign a standby BlackBerry Enterprise Server to a primary BlackBerry Enterprise Server. You can
assign only one standby
BlackBerry Enterprise Server to each primary BlackBerry Enterprise Server. The setup application
assigns the SRP credentials of the primary BlackBerry Enterprise Server to the standby BlackBerry Enterprise Server
automatically.
When you install a standby BlackBerry Enterprise Server, you can install the same BlackBerry Enterprise Server
components that are installed on the primary BlackBerry Enterprise Server, or different components. For example, you
might want to install additional components with the standby BlackBerry Enterprise Server if you want to use the system
resources on the computer to distribute the performance load.
You cannot change a primary BlackBerry Enterprise Server to a standby BlackBerry Enterprise Server by running the setup
application again.
By default, the standby BlackBerry Enterprise Server enables you to fail over the following components if they stop
responding on the primary BlackBerry Enterprise Server:
BlackBerry Attachment Service
BlackBerry Collaboration Service
BlackBerry Dispatcher
BlackBerry MDS Connection Service
BlackBerry Messaging Agent
BlackBerry Policy Service
BlackBerry Router
BlackBerry Synchronization Service
After you complete the installation process, the setup application does not start all the services for the standby BlackBerry
Enterprise Server
components. For example, the setup application does not start the BlackBerry Mail Store Service,
BlackBerry Synchronization Service, or BlackBerry Policy Service. The failover process starts the services when the
standby BlackBerry Enterprise Server promotes itself.
For more information about high availability in a large-scale environment, see the BlackBerry Enterprise Server Planning
Guide.
