Changing when automatic failover occurs bycustomizing the health parameters for user accountsand messaging servers
By default, the health parameters for user accounts and messaging servers use percentages to determine when a
BlackBerry Enterprise Server instance is unhealthy. The User accounts health parameter indicates a BlackBerry Enterprise
Server instance is unhealthy if less than 75% of the user accounts are started. The Connection to the messaging server(s)
health parameter indicates that a BlackBerry Enterprise Server instance is unhealthy if the BlackBerry Enterprise Server
instance cannot connect to at least 75% of the messaging servers in your organization.
If either of these health parameters indicate that the primary BlackBerry Enterprise Server is unhealthy and you turn on
automatic failover, the BlackBerry Enterprise Server starts the failover process. You can change the percentages of these
health parameters to customize when you want automatic failover to occur in your organization's environment.
For example, if your organization requires that all users can access email messages from BlackBerry devices at all times
and that the BlackBerry Enterprise Server is connected to all of the messaging servers at all times, you can change the
value of the Connection to the messaging server(s) health parameter to 100%.
