Process flow: Synchronizing subsequent changes to organizer data


This diagram shows the components that are described in the following text.

  1. A user saves a change to the organizer data or BlackBerry® device settings (for example, a new AutoText entry) on a BlackBerry device or in the organizer application on the user's computer.
  2. Depending on where the user made the change, the BlackBerry device or the BlackBerry® Enterprise Server adds the change to a changelist and sends the changelist to the BlackBerry Synchronization Service.

    The changelist includes the target database and record information for the organizer application.

  3. The BlackBerry Synchronization Service sends a change to organizer data over the wireless network, along with other entries in the changelist for the user.

    The BlackBerry Synchronization Service sends other changes, including BlackBerry device information, time zone information, and backup and restore data, at the batch synchronization interval that is set on the BlackBerry Enterprise Server. By default, the batch synchronization interval is 10 minutes.

    To prevent synchronization errors, the BlackBerry Enterprise Server and BlackBerry device can send only a single changelist at a time for a user account.

    The BlackBerry Synchronization Service writes a synchronization request entry to the SynchRequest table of the BlackBerry Configuration Database, and sends the changed records to the BlackBerry Dispatcher.

  4. The BlackBerry Dispatcher compresses the content, encrypts it using the device transport key of the BlackBerry device, and sends the encrypted content to the BlackBerry Router for delivery to the BlackBerry device.
  5. The BlackBerry device sends a delivery confirmation to the BlackBerry Synchronization Service for each record that it receives.
  6. The BlackBerry Synchronization Service receives delivery confirmations, deletes the corresponding synchronization request entries from the SyncRequest table, and writes an entry to the SyncRecordState table for each delivery confirmation.

    Each organizer database record has a unique identifier that is mapped to a corresponding record on the BlackBerry device.
