BlackBerry MVS high availability
6
BlackBerry® Mobile Voice System high availability consists of an active MVS Session Manager and a standby MVS
Session Manager. You can use high availability to help provide minimum downtime for BlackBerry MVS users if one
of your organization's MVS Session Manager instances stops responding or requires maintenance. The failover
process is designed to be automatic, but you can perform a manual failover before you perform scheduled
maintenance.
When you configure the BlackBerry MVS for high availability, you install the MVS Console, active MVS Session
Manager, and standby MVS Session Manager on different computers in the same BlackBerry Domain. Both MVS
Session Manager instances use the same MVS Console and BlackBerry Configuration Database.
Both MVS Session Manager instances connect to the MVS Console. The MVS Console periodically checks that the
active MVS Session Manager is healthy. If the health of the active MVS Session Manager falls below the failover
threshold or if the active MVS Session Manager stops responding, the MVS Console promotes the standby MVS
Session Manager.
If any of your organization's users are on BlackBerry MVS calls when the active MVS Session Manager stops
responding, the calls remain active but the users cannot use the features that are typically available to them during
a call. While the active MVS Session Manager fails over, the users cannot send or receive any BlackBerry MVS calls
until the failover process completes.
