Stopping a Synchronization Task

After the source database and services are migrated to the destination database, you can stop the synchronization task. To prevent data from being overwritten after the source database and services are migrated to the destination database, stop a synchronization task to achieve this goal.

You can stop a task in any of the following statuses:

  • Creating
  • Configuration
  • Pending start
  • Full synchronization
  • Full synchronization failed
  • Incremental synchronization
  • Incremental synchronization failed
  • Paused
  • Fault rectification
  • You are advised to stop the task before performing other operations, such as disconnecting the network between the source database and the synchronization instance. Otherwise, an alarm indicating that the source database cannot be connected will be generated.
  • For a task in the Configuration state, it cannot be stopped if it fails to be configured.
  • For a task in the Fault rectification state, it cannot be stopped if the fault is being rectified.
  • After a task is stopped, it cannot be retried.

Procedure

  1. In the task list on the Data Synchronization Management page, locate the target task and click Stop.
  2. In the displayed dialog box, click Yes.

    • If the task status is abnormal (for example, the task fails or the network is abnormal), DRS will select Forcibly stop task to preferentially stop the task to reduce the waiting time.
    • Forcibly stopping a task will release DRS resources. Check whether the synchronization is affected.
    • To stop the task properly, restore the DRS task first. After the task status becomes normal, click Stop.
    • For a DRS task that is in the incremental state and with MySQL serving as the source database, after you select Display breakpoint information when the task is stopped when you stop the task, the GTID and binlog position information of the source database will be displayed on the synchronization progress page after the task is stopped.

Stopping Tasks

  1. On the Data Synchronization Management page, select the tasks to be stopped.
  2. Click Batch Operations in the upper left corner and choose Stop.

  3. In the displayed dialog box, confirm the task information and click Yes.
