Mobile Channel Interfaces

Two main channel interfaces provide notifications and data transport to and from remote devices.

• The messaging channel serves as the abstraction to all device-side notifications (BlackBerry Enterprise Service, Apple Push Notification Service, and others) so that when changes to back-end data occur, devices can be notified of changes relevant for their application and configuration.

  The messaging channel sends these types of communications:

  • Application registration - the messaging channel is used for application registration before establishing a connection to the Unwired Server.
  • Change notifications - when the Unwired Server detects changes in the back-end EIS, the Unwired Server can send a notification to the device. By default, sending change notifications is disabled, but you can enable sending change notifications per synchronization group.

    To capture change notifications, you can register an onSynchronize callback. The synchronization context in the callback has a status you can retrieve.

  • Operation replay records - when synchronizing, these records are sent to the Unwired Server and the messaging channel sends a notification of replayFinished. The application must call another synchronize method to retrieve the result.
  • SAP Data Orchestration Engine (DOE) application synchronization - the messaging channel is used for synchronization for DOE applications.
• The synchronization channel sends data to keep the Unwired Server and client synchronized. The synchronization is bi-directional.
