Migrate a connector

The OPS & Monitoring module of OceanBase Migration Service (OMS) Community Edition allows you to migrate a connector in high availability scenarios.

Limits

• You can migrate a connector in the Stopped or Abnormal state only when multiple servers are available in a high availability scenario.

• If no node is selected during the migration, the system automatically schedules the connector to a server that has not experienced any performance bottleneck, but not necessarily with the lowest usage.

• If a node is selected during the migration, the tag and quota of the server can be ignored, but the server must be able to run the connector.

Application scenarios

In high availability scenarios, you can migrate connectors in the following cases:

• A server is replaced, and connectors on the server need to be migrated to a new server.

• The number of task processes on a heavy-loaded server needs to be reduced for load balancing.

Procedure

1. Log on to the console of OMS Community Edition.

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, synchronization project name or ID, or server IP address.

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

   • If the cluster is deployed in multiple regions, you can find the target region in the region column and migrate the connector in the target region.

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

6. (Optional) In the dialog box that appears, select a node to which you want to migrate the connector.

7. Click Migrate.
