• To change the percentage of the health parameter for messaging servers for a BlackBerry Enterprise Server
pair, type traittool.exe -host <instance_name> -trait ServerHealthPercentage -set <value>, where
<instance_name> is the name of the primary BlackBerry Enterprise Server instance and <value> is the
percentage that you want to change the health parameter to.

pair and the primary BlackBerry Enterprise Server instance is named server03, you can type traittool.exe -host
server03 -trait UserHealthPercentage -set 80.

If you want to change the percentage of the Connection to the messaging server(s) health parameter to 60% for all
BlackBerry Enterprise Server instances, you can type traittool.exe -global -trait ServerHealthPercentage -set 60.
Prerequisites: Configuring the BlackBerry Enterprise Server
pair to fail over automatically
• Install a primary BlackBerry® Enterprise Server.
• Install a standby BlackBerry Enterprise Server. For more information about installing a standby BlackBerry
Enterprise Server, see the BlackBerry Enterprise Server Installation and Configuration Guide.
• Configure the health parameters to meet your organization's requirements.
• Specify the same proxy mappings for the BlackBerry MDS Connection Service instances on the primary and
standby BlackBerry Enterprise Server instances.
Configure the BlackBerry Enterprise Server to fail over
automatically
When you configure the BlackBerry® Enterprise Server to fail over automatically, the BlackBerry Enterprise Server
can start the failover process automatically depending on the health of the primary BlackBerry Enterprise Server and
the standby BlackBerry Enterprise Server. The health parameters must be greater than the failover threshold and
indicate that the primary BlackBerry Enterprise Server is unhealthy. The health parameters must also be greater than
the promotion threshold and indicate that the standby BlackBerry Enterprise Server is healthy. After the failover
process occurs, the BlackBerry Enterprise Server turns off automatic failover.
1. In the BlackBerry Administration Service, on the Servers and components menu, expand High availability >
Highly available BlackBerry Enterprise Servers.
2. Click the name of the BlackBerry Enterprise Server pair that you want to turn on automatic failover for.
3. Click Turn on automatic BlackBerry Enterprise Server failover.
In the System status section, the value for the Automatic BlackBerry Enterprise Server failover mode field changes
to True.
