You cannot configure high availability for the MVS Console because you can install only one MVS Console in a
BlackBerry Domain.
To manage your organization's users, if the computer that you installed the MVS Console on stops responding, you
should determine why the MVS Console stopped responding. Alternatively, you can install another MVS Console
instance and connect it to the active and standby MVS Session Manager instances.
Support for BlackBerry Enterprise Server failover
The BlackBerry® Mobile Voice System supports BlackBerry® Enterprise Server failover. If any of your organization's
users are on BlackBerry MVS calls when the active BlackBerry Enterprise Server stops responding, the calls remain
active, but the users cannot use the features that are typically available to them during a call. The users also cannot
send or receive a second call. While the active BlackBerry Enterprise Server fails over, the users cannot send or receive
any BlackBerry MVS calls until the failover process completes.
Support for PBX failover
The BlackBerry® Mobile Voice System does not support PBX failover. If any of your organization's users are on
BlackBerry MVS calls when the active PBX stops responding, the calls remain active until the BlackBerry device stops
receiving registration messages from the PBX. The users cannot send or receive any new BlackBerry MVS calls until
the PBX is active again or until you associate the affected telephony connector with the standby PBX.
How the BlackBerry MVS determines the health of MVS
Session Manager instances
The MVS Console determines the health of the MVS Session Manager instances by monitoring its connection to the
MVS Session Manager instances. If the active MVS Session Manager sends a network ping to the MVS Console at
regular intervals, the MVS Console keeps the MVS Session Manager active. If the active MVS Session Manager does
not send a network ping to the MVS Console every 60 seconds, the MVS Console promotes the standby MVS Session
Manager to be the active MVS Session Manager.
Conditions for failover to a standby MVS Session Manager
Failover from the active MVS Session Manager to the standby MVS Session Manager occurs when the MVS Console
stops receiving network pings from the active MVS Session Manager for 1 minute. If the MVS Console continues to
receive network pings from the standby MVS Session Manager, the MVS Console starts the failover process.
