To help it react to a failover recovery of the service manager, the Parlay Connector can use two different interfaces to receive events. These events notify the Parlay Connector when the service manager goes offline and when it becomes available again.
The Parlay Connector uses the IpAppEventNotification interface to receive events related to the availability of the service manager.
The notification registration for IpAppEventNotification occurs after the Parlay Connector has signed service agreements with the Parlay gateway. The Parlay Connector queries for the list of service types available at the Gateway and registers event notifications for each of the service types.
The implementation of this interface applies to both 3x and 4x Parlay gateways.
The Parlay Connector also implements the IpAppFaultManager interface to receive events related to the availability of the service manager.
Different methods are used for Parlay 3x and Parlay 4x.
Note that availability cannot be reported in Parlay 3x through the IpAppFaultManager interface.
