Add synchronization objects

Last Updated: Jul 03, 2017

DTS supports the modification of synchronization objects during the synchronization process. This section introduces how to add synchronization objects during the synchronization process.

Restriction

Only when the synchronization task is in Synchronization in process or Synchronization failed status can the synchronization object be modified.

Start time

When adding a new synchronization object, the synchronization start time varies whether the synchronization task is subject to synchronization initialization. The details are as follows:

  • If the synchronization task is subject to synchronization initialization, the newly added object also performs synchronization initialization and then starts the data replication.

  • If the synchronization task is not subject to synchronization initialization, the synchronization object starts to replicate incremental data generated on the source instance from the current time point.

Procedure

  1. Log on to the Alibaba Cloud DTS console.

  2. On the Data synchronization page, click More > Revise the synchronization object for the data synchronization instance of which you want to modify the synchronization object.

  3. On the synchronization object selecting page, add the objects to be synchronized.

  4. After the modification, pre-check starts. Once the pre-check is successful, click Start to complete the object adding process.

If the synchronization task needs initialization, after the synchronization object is added, the task status will change from Synchronizing to Synchronizing (Newly added object in initialization Details). At this time, the background will restart the synchronization task and the synchronization latency will be changed to -1s. Once the restart is successful, the latency and synchronization speed will return to normal.

In the synchronization task list, you can click Details to view the progress details of the initialization for the newly added object. After the newly added synchronization object completes the initialization, the synchronization task status returns to Synchronizing.
