Usage tips
-
This tool is used when synchronizing replicas in disconnected mode. Additionally see the Import Message, Export Acknowledgement Message and Re-Export Unacknowledged Messages tools. To synchronize replicas in a connected mode see the Synchronize Changes tool.
-
The following environment settings affect this tool: workspace, scratch workspace, and Configuration keyword.
Command line syntax
An overview of the Command Line window
ExportDataChangeMessage_management <in_geodatabase> <out_data_changes_file> <in_replica> {switch_to_receiver} {include_unacknowledged_changes} {include_new_changes}
| Parameter | Explanation | Data Type |
| <in_geodatabase> |
Specifies the replica geodatabase from which to export the data change message from. The geodatabase may be local or remote. |
Workspace | GeoDataServer|GPComposite |
| <out_data_changes_file> |
Specifies the delta file to export to. |
File |
| <in_replica> |
The replica containing updates to be exported. |
String |
| {switch_to_receiver} |
Indicates whether to change the role of the replica to that of a receiver. The receiver may not send replica updates until updates from the relative replica sender arrive.
|
Boolean |
| {include_unacknowledged_changes} |
Indicates whether to include data changes that have been previously exported for which no acknowledgement message has been recieved.
|
Boolean |
| {include_new_changes} |
Indicates whether to include all data changes created since the last exported data change message.
|
Boolean |
Command line example
ExportDataChangeMessage Countries.mdb d:\delta.mdb MyReplica1 TRUE FALSE TRUE
