To reduce redundant JDBCWriters, you can delete JDBCWriters that are in the abnormal or stopped state.
Procedure
Log on to the console of OceanBase Migration Service (OMS) Community Edition.
In the left-side navigation pane, choose OPS & Monitoring > Component.
On the Component page, click the JDBCWriter tab.
On the JDBCWriter page, search for the JDBCWriter that you want to pause by its name or server IP address. You can also perform a fuzzy search by migration project name or ID. The target JDBCWriter must be in the Abnormal or Stopped state.
For single-region deployment, the region information is displayed on the right of JDBCWriter.
For multi-region deployment, you can filter JDBCWriters by region and delete the specified JDBCWriters from corresponding regions.
Click the More icon in the Actions column of the target JDBCWriter and choose Delete.
In the Deletion Confirmation dialog box, enter delete to confirm the operation.
Click Delete.
