Data Transmission Service:Start a DTS task

Last Updated:Mar 28, 2026

Start a data synchronization, data migration, or change tracking task in Data Transmission Service (DTS) to run or resume the task.

Prerequisites

Before you begin, make sure that you have:

  • Completed the Advanced Settings step for the DTS task, so the task appears on the Tasks page

  • Reviewed DTS billing information, including billable items, billing methods, and billing rules. For more information, see Billing overview

The task status must be one of the following before you can start it:

StatusDescriptionCan start?
Not StartedTask is configured but has never runYes
Precheck PassedTask passed the precheck and is ready to runYes
PausedTask was paused. For example, if paused for more than 7 days, the task cannot be resumed and must be reconfiguredYes, if paused fewer than 7 days
FailedTask encountered an error. If the task has been in this state for an extended period, the task data is deletedYes, if task data is not deleted
CompletedTask has finishedNo

Usage notes

  • Verify that the parameter settings are correct before starting a task.

  • Some tasks require additional operations before they can start. Complete those operations based on your business requirements.

Start a task

The following example uses a data synchronization task. The steps are the same for data migration and change tracking tasks.

  1. Go to the Data Synchronization Tasks page. You have two options:

  2. Select the region where the data synchronization instance resides.

    In the DMS console, select the region on the right side of Data Synchronization Tasks. In the DTS console, select the region in the top navigation bar.
  3. Start the task.

    • Start a single task:

      1. Find the task you want to start.

      2. Click Start Task in the Actions column.

      3. In the Note message, click Start Task.

    • Start multiple tasks at a time:

      1. Select the tasks you want to start.

      2. Click Start Task in the lower-left corner of the page.

      3. In the dialog that appears, click OK.

  4. Optional: Complete any subsequent operations as prompted.

FAQ

Why did my task fail to start?

The most common reasons are:

  • Subsequent operations are incomplete. Some tasks require additional steps before they can start. Check the task details for any pending actions.

  • The task has an error that must be fixed. Fix the error and try to start the task again.

  • The task has been paused or in a failed state for too long. If a task is paused or failed for an extended period, DTS deletes the task data, and the task can no longer be started. Reconfigure the task to continue.

Can I start a task that is in the Completed state?

No. Tasks in the Completed state cannot be restarted.
