Data replication

Alcatel-Lucent OmniTouch Advanced Communications Servers support automated
failover within a stack to provide high availability. This is done by designating a Secondary
server to be a synchronized backup to its respective Primary server. For a thorough
explanation of Data Replication, see the OmniTouch My Teamwork Unified
Conferencing and Collaboration Application Site Preparation Guide.
The Data Replication feature applies to pairs of Application Servers (Redundancy Pair)
within a stack. Before enabling Data Replication, you MUST configure the Redundancy
Pair as a stack through
within a stack, not between remote sites.You must have one Primary and one Secondary
Application Server per stack to take advantage of the Data Replication feature. Under
normal conditions, users should only be provisioned on the Primary Application Server,
but may be provisioned on the Secondary in the case where the Primary server is
unavailable.
Once enabled, replication occurs continuously in near real-time over the stack backplane.
The information is unencrypted. If you re-configure the stack at any time to disable Data
Replication, the secondary server's database should be cleared before it is re-enabled.
Replication works best if, once enabled, it is left enabled at all times.
Important!

be transferred to the secondary. If not, the replication process to the secondary will fail
due to the missing item.
