For replicas in a disconnected environment, synchronization requires the user to manually perform the message exchange. This is achieved by exporting a message from one replica to a file, transporting the file on a DVD or by other means, and then importing the file to the relative replica.
When replicating in this type of environment, it is important for the data receiver to send an acknowledgment message after receiving data changes as often as possible. If no acknowledgment messages are received, the data sender resends changes and maintains the information needed to resend changes until those changes are acknowledged. As a result, the data sender's geodatabase can become large and new data change messages can also become large.
One acknowledgment message acknowledges all data change messages. For example, if a replica receives three data change messages and imports each, it can send a single acknowledgment message to acknowledge all three.
Use the Export Acknowledgment Message wizard or Export Acknowledgment Message geoprocessing tool command to export acknowledgment messages. When working with these, you specify the replica to export from and XML file that will be created.
- The Export Acknowledgment Message wizard can be opened in two different ways: from the Distributed Geodatabase toolbar or from the context menu of the geodatabase or geodata service.
- In ArcMap, open the Distributed Geodatabase toolbar and click the Export Acknowledgment Message button.
- In the Catalog window, right-click the geodatabase or geodata service published through ArcGIS Server from which you want to export an acknowledgment message, point to Distributed Geodatabase, and click Export Acknowledgment Message.
The wizard supports both local and remote geodatabases. Remote geodatabases are accessed in ArcMap through map services that have the geodata access capability enabled.
- Select the replica from which you would like to export the acknowledgment message.
The replica type is displayed.
- Specify the name of the acknowledgment file to be created.
