Export Acknowledgement Message (Data Management)

Summary

Creates an output acknowledgement file to acknowledge the reception of previously received data change messages.

Usage

• Use this tool when synchronizing a replica while disconnected. First run the Export Data Change Message tool, which creates a delta file with changes to synchronize. Then copy and import the delta file to the relative replica using the Import Message tool. If the delta file gets lost and you want to resend, use the Re-Export Unacknowledged Messages tool to regenerate the delta file. After the changes are imported, you can export an acknowledgment file from the relative replica using the Export Acknowledgement Message tool. Copy and import the acknowledgment file using the Import Message tool. If the acknowledgment is not received, the next time changes are sent, they will include the new changes and the previously sent changes.

• The geodatabase can be a local geodatabase or a geodata service.

• The output acknowledgement file must be XML.

• This tool is not applicable for check-out replicas.

• To synchronize replicas in a connected mode, see the Synchronize Changes tool.
