Feature and Technical Overview

BlackBerry Enterprise Server high availability

High availability in a distributed environment

If you install multiple BlackBerry Enterprise Server components on different computers to create a distributed environment, you can configure the components for high availability. High availability for a distributed component requires that you install two or more instances of the component in your organization's environment. When an instance stops responding, the other instances can take over.

When you install multiple BlackBerry Enterprise Server components in a distributed environment, each BlackBerry Enterprise Server component implements high availablility differently.

primary group. If the primary group cannot convert a

 

 

specific file format, the BlackBerry Enterprise Server

 

 

forwards conversion requests for the specific file format to

 

 

the secondary group.
