Impacts and recommendations

During the restart periods of Database Gateway servers, the retry status may appear for the DTS tasks created to migrate data from self-managed databases that are connected to Database Gateway. The service will be resumed within minutes.

During the restart time windows, if you perform any online DDL operations on the source databases, DTS tasks fail. Therefore, we recommend that you do not perform online DDL operations during the time windows.
