This topic describes how to start, pause, or resume a data synchronization task.
Start a data synchronization task
If you have created a data synchronization task but did not start it after it passed the pre-check, you can find the task in the list of synchronization tasks and start it.
Log in to the OceanBase Migration Service (OMS) console.
In the left-side navigation pane, click Data Synchronization.
On the Synchronization Tasks page, click Start in the Actions column of the task that you want to start.
You can also click the task name on the Data Synchronization page to go to the details page, and click Start in the upper-right corner.
In the dialog box that appears, click OK.
Pause a data synchronization task
You can pause a data synchronization task only when it is in the Running state. After you pause a data synchronization task, OMS stops scheduling the data synchronization task, and the latency increases in real time.
Log in to the OMS console.
In the left-side navigation pane, click Data Synchronization.
On the Synchronization Tasks page, click Pause in the Actions column of the data synchronization task that you want to pause.
You can also click the task name on the Data Synchronization page to go to the details page, and click Pause in the upper-right corner.
In the dialog box that appears, click OK.
Notice
This operation will pause the synchronization component. The task cannot be recovered if it is paused for more than 12 hours.
Resume a data synchronization task
You can manually resume a data synchronization task that is in the Stopped or Failed state. After you resume the task, OMS continues to run the data synchronization task and reduces the synchronization latency as soon as possible.
Log in to the OMS console.
In the left-side navigation pane, click Data Synchronization.
On the Synchronization Tasks page, click Resume in the Actions column of the data synchronization task that you want to resume.
You can also click the task name on the Data Synchronization page to go to the details page, and click Resume in the upper-right corner.
In the dialog box that appears, click OK.
