You can start a data synchronization, data migration, or subscription instance that has a status such as Not Started, Paused, or Failed to Start. This allows the instance to run or resume normal operations. Before you start the instance, confirm that its configuration is correct.
Prerequisites
The instance has passed the Advanced Settings step and is displayed on the task list page. For example, the Status of the instance is Not Started, Precheck Passed, Paused, or Failed.
For more information about configuration, see Configure data validation, Overview of data synchronization solutions, Overview of data migration solutions, and Overview of data subscription solutions.
You are familiar with the billable items, billing methods, and billing rules of DTS. For more information, see Billing overview.
Usage notes
Before you start an instance, make sure that its parameter settings are correct.
An instance that has been in the Paused or Failed state for a long time cannot be started. For example, an instance that has been paused for more than seven days cannot be resumed.
Some instances require additional operations before they can run properly. Perform these operations as needed.
Procedure
This topic uses a data synchronization instance as an example to describe how to start an instance.
Go to the data synchronization task list page in the destination region. You can do this in one of two ways.
DTS console
Log on to the DTS console.
In the navigation pane on the left, click Data Synchronization.
In the upper-left corner of the page, select the region where the synchronization instance is located.
DMS console
NoteThe actual steps may vary depending on the mode and layout of the DMS console. For more information, see Simple mode console and Customize the layout and style of the DMS console.
Log on to the DMS console.
In the top menu bar, choose .
To the right of Data Synchronization Tasks, select the region of the synchronization instance.
Find the destination instance.
Start the instance.
Start a single instance
You can find the destination instance.
In the Actions column of the destination instance, choose
> Start Task.In the Note dialog box that appears, click Start Task.
Start instances in a batch
Select multiple destination instances.
At the bottom of the page, click Start Task.
In the OK dialog box that appears, click OK.
Optional: Complete any subsequent operations as prompted.
The instance automatically runs after it is started. The final status of a successfully started instance is one of the following:
Data synchronization instance: Running
Subscription instance: Normal
Data migration instance: Running
NoteFor a migration instance that does not include an incremental task, the final status is Completed.
Data validation instance: Running
NoteFor a validation instance that does not include an incremental validation task, the final status is Completed.

FAQ
What are the possible causes of startup failures?
The required subsequent operations for the instance are not complete.
An error that requires a fix has occurred. Fix the error and try again.
The instance has been in the Paused or Failed state for too long. The related data has been purged, which prevents the instance from starting. You must reconfigure the task.
Can an instance in the Finished state be started?
No, it cannot.
