The Teradata Notification Service is aware of the two Viewpoint servers that are part of the cluster configuration. The initial state of the primary and secondary Viewpoint servers is maintained by the service.
After disabling the Viewpoint clustering, the Teradata Alerts components running on the Viewpoint servers are restarted as two standalone Viewpoint servers. The Teradata Notification Service automatically detects the configuration change within five minutes and reconfigures the service as the Teradata Notification Service for the initial primary Viewpoint server. If this is not the appropriate Teradata Alerts configuration, the service should be manually configured with the location of the Viewpoint server.
