Changing the promotion threshold and failover threshold

Each primary and standby BlackBerry® Enterprise Server instance has a failover threshold and a promotion threshold. The BlackBerry Enterprise Server uses the failover threshold when it is an primary instance to determine when it needs to demote itself, and it uses the promotion threshold when it is a standby instance to determine whether it can promote itself to become the primary instance.

You can configure the thresholds for each BlackBerry Enterprise Server pair.

Change the promotion threshold and failover threshold and the order of the health parameters

You can change the promotion threshold and failover threshold and the order of the health parameters to meet the requirements of your organization.
