Administration Guide Configuring BlackBerry Enterprise Server high availability Configuring BlackBerry Enterprise Server high 9 availability Check the health of a BlackBerry Enterprise Server If you configured BlackBerry® Enterprise Server high availability, you can check the health of a BlackBerry Enterprise Server instance to verify that it is running as expected. 1. In the BlackBerry Administration Service, in the Servers and components menu, expand High availability. 2. Click High availablity summary. 3. In the Host instance name field, click the name of a BlackBerry Enterprise Server pair. 4. Click More. The BlackBerry Administration Service displays the status of the health parameters. Availability state and failover status of the BlackBerry Enterprise Server When you check the health of a BlackBerry® Enterprise Server instance in the BlackBerry Administration Service, you can also check the availability state and failover status of the BlackBerry Enterprise Server instance. The availability state specifies whether the BlackBerry Enterprise Server instance is a primary instance or standby instance according to information from the BlackBerry Configuration Database. If you did not connect the BlackBerry Enterprise Server to the BlackBerry Configuration Database, the BlackBerry Administration Service might not display up-to-date information about the availability state. The failover status specifies whether the BlackBerry Enterprise Server instance is a primary instance or standby instance and whether the BlackBerry Enterprise Serverinstance is running as expected. The BlackBerry Administration Service receives this information in real time from the BlackBerry Enterprise Server instance so that the failover status is always up-to-date. How the BlackBerry Enterprise Server uses health parameters The BlackBerry® Enterprise Server uses health parameters to define the failover and promotion thresholds. The health parameters indicate if a BlackBerry Enterprise Server service or component is healthy or unhealthy. For example, the value for the Wireless network access health parameter indicates whether the BlackBerry Router can access the wireless network. The health parameters are identical for both the failover threshold and the promotion threshold. You can choose the health parameters for the services and components that are important to your organization. After you choose the health parameters that you want the BlackBerry Enterprise Server to use to determine when an automatic failover process should occur, the failover process can occur automatically if all of the following conditions are present: 87

Configuring BlackBerry Enterprise Server high
availability

Check the health of a BlackBerry Enterprise Server
If you configured BlackBerry® Enterprise Server high availability, you can check the health of a BlackBerry Enterprise
Server instance to verify that it is running as expected.
1.
In the BlackBerry Administration Service, in the
Servers and components
menu, expand
High availability
.
2.
Click
High availablity summary
.
3.
In the
Host instance name
field, click the name of a BlackBerry Enterprise Server pair.
4.
Click
More
.
The BlackBerry Administration Service displays the status of the health parameters.
Availability state and failover status of the BlackBerry Enterprise Server
When you check the health of a BlackBerry® Enterprise Server instance in the BlackBerry Administration Service, you
can also check the availability state and failover status of the BlackBerry Enterprise Server instance.
The availability state specifies whether the BlackBerry Enterprise Server instance is a primary instance or standby
instance according to information from the BlackBerry Configuration Database. If you did not connect the BlackBerry
Enterprise Server to the BlackBerry Configuration Database, the BlackBerry Administration Service might not display
up-to-date information about the availability state.
The failover status specifies whether the BlackBerry Enterprise Server instance is a primary instance or standby
instance and whether the BlackBerry Enterprise Serverinstance is running as expected. The BlackBerry Administration
Service receives this information in real time from the BlackBerry Enterprise Server instance so that the failover status
is always up-to-date.
How the BlackBerry Enterprise Server uses health
parameters
The BlackBerry® Enterprise Server uses health parameters to define the failover and promotion thresholds. The
health parameters indicate if a BlackBerry Enterprise Server service or component is healthy or unhealthy. For
example, the value for the Wireless network access health parameter indicates whether the BlackBerry Router can
access the wireless network. The health parameters are identical for both the failover threshold and the promotion
threshold. You can choose the health parameters for the services and components that are important to your
organization.
After you choose the health parameters that you want the BlackBerry Enterprise Server to use to determine when
an automatic failover process should occur, the failover process can occur automatically if all of the following
conditions are present:
