Resetting a Synchronization Task
During real-time synchronization, you can reset the synchronization tasks in one of the following statuses so that you do not need to configure the tasks again.
- Paused
- Failed
For details about the synchronization scenarios where synchronization tasks can be reset, see Real-time Synchronization Scenarios Where Synchronization Tasks Can Be Reset.
- For a many-to-one synchronization task, only the parent task can be reset.
- For a MySQL many-to-one synchronization task, only the subtask can be reset.
- Resetting a task does not clear the destination database. You can determine whether to clear the destination database based on your service requirements. After the task is reset, a full synchronization is performed again. You do not need to configure the task again.
Prerequisites
You have logged in to the DRS console.
Method 1
- In the task list on the Data Synchronization Management page, locate the target task and click Reset in the Operation column.
- In the displayed dialog box, check the synchronization task again.
If a many-to-one synchronization task fails to be reset, click the name of the failed subtask in the failure details to view the failure cause of the task.
- After the check is complete and the check success rate is 100%, click Start to submit the synchronization task again.
Method 2
Real-time Synchronization Scenarios Where Synchronization Tasks Can Be Reset
- MySQL->MySQL
- MySQL->GaussDB(DWS)
- PostgreSQL->PostgreSQL
- Oracle -> GaussDB(DWS) (Only tasks in the failed state can be reset.)
- MySQL->MySQL
- MySQL -> Kafka (Only tasks in the failed state can be reset.)
