Update the configurations of a connector

OceanBase Migration Service (OMS) Community Edition allows you to view and update the configurations of a specified connector. When you update the configurations, the current configurations of the connector are displayed by default. You can view or modify the configurations of the connector.

Limits

• OMS Community Edition allows you to update the configurations of only a stopped or abnormal connector.

• After you update the configurations of a connector, the system will restart the connector to apply the updates. Proceed with caution.

  When a data synchronization project fails, check the configurations of the project first, such as the basic information and user privileges of the source and destination databases.

• Some connector configurations cannot be modified. If these configurations are modified, errors will be generated in the corresponding ticket.

• The source address, subtopics, and destination address cannot be modified.

Application scenarios

You can update connector configurations in the following scenarios:

• A data synchronization project fails due to incorrect configuration information.

• A data synchronization project needs to be optimized.

Procedure

1. Log on to the OMS Community Edition console.

2. In the left-side navigation pane, choose OPS & Monitoring > Component.

3. On the Component page, click the Connector tab.

4. On the Connector tab, you can search for the target connector by connector name, IP address, or data synchronization project.

   • For single-region deployment, the region information is displayed on the right of Connector.

   • For multi-region deployment, you can filter connectors by region and update connectors in the target region.

5. Click Update in the Actions column of the target connector.
