Configuring Synchronization Groups

Configure a synchronization group when a collection of MBOs must be synchronized at the same time.

The synchronization group defines both the logical unit of synchronization, and generation frequency for data notifications. The latter influences the synchronization frequency for replication synchronization applications, which usually need to perform a synchronization event to download the changes associated with the data notification event.

The synchronization group properties jointly determine the frequency with which data changes are detected, and notifications are generated. The actual data notification delivery to the application is determined by this equation:

delivery of data notification = cache schedule repeat value or data change notification arrival time + synchronization group change detection interval value + device's subscription push interval setting

There may be an additional 10 second delay, because the internal thread for performing the change detection runs every 10 seconds.

In the left navigation pane, expand the Packages folder and select the package containing the sync group you want to configure.
Select the desired sync group and click Properties.
Select a change detection interval. This value determines how frequently Unwired Server looks for changes to MBOs, and generates push notifications. The default is 1 hour.
If you set the Change detection interval to 0, the change detection task is disabled and the SUP server does not push changed messages or data to the client device.
Click OK.
