Business Continuity Manager can sustain prolonged, planned outages without taking applications offline. Planned outages can be short outages for simple maintenance work or restarts to more prolonged outages for Teradata system upgrades, or full replacements.
Business Continuity Manager tracks the Teradata system state which can be changed to control access to the system. The system state is employed for passive and managed routing. Using the HALT operation, you can close and stop all sessions on a Teradata system. If a user routing rule allows the sessions to failover to the standby system, the sessions can failover when the active system becomes out of service. Business Continuity Manager recovery of managed sessions is the second mechanism that allows Teradata systems to re-sync automatically.
