Overview - Nortel Call Center Server Installation And Maintenance Manual

Using Symposium Standby Server

Overview

Introduction
The Symposium Standby Server feature supports a "warm standby"
configuration that allows a backup server (Standby Server) to run your call
center if the primary server (Active Server) fails. You configure the Standby
Server for Symposium Call Center Server in exactly the same way as the Active
Server for your Symposium Call Center Server, with identical scripts, agents,
and so on. However, you do not connect the Standby Server to the switch.
If the Active Server fails, or if you decide to stop its service for a while,
disconnect the Active Server from the switch and connect the Standby Server to
take over operation of the call center. This avoids costly down-time for the call
center.
You can use the Symposium Standby Server feature with Symposium Call
Center Server nodal servers.
The Symposium Standby Server feature uses Sybase's Replication Server
product to maintain a pair of Symposium Call Center Server databases—an
Active Server database and a Standby Sever database. The Active Server
database belongs to the Active Server, while the Standby Server database
belongs to the Standby Server.
The Replication Server runs on a dedicated server that is separate from either the
Active Server or the Standby Server.
During normal call processing, the Active Server updates its database on a
regular basis. The Replication Server copies the database updates to the Standby
Sever's database. The Replication Server updates the Standby Server database in
the same manner as the Active Server updates its database. This maintains
consistency between the databases.
