Scenarios
For synchronization tasks in certain statuses, Data Transfer Service (DTS) allows you to return to the Set Up Synchronization Source and Target Databases page to modify connection information.
Must-Knows
1. Modifying the instance connection information may cause data synchronization to be interrupted due to insufficient account permissions or changes to the source instance, thus affecting the normal operation of the migration link.
2. For all tasks, the system automatically retries the task after the instance connection information is modified, which may cause a brief interruption.
3. When the status of the synchronization task is Running/Task Error, modifying connection information is supported.
Operation Steps
1. Log in to the DTS console, select the Data Sync page in the left sidebar, select the specified synchronization task, and choose More > Modify connection information in the Operation column. 2. On the Set source and target databases page, modify parameters such as the host address, port, account, and password for the source and target databases according to actual needs. After connectivity testing, click Save.
