To reduce redundant JDBCWriters, you can delete JDBCWriters that are in the completed or abnormal state.
Procedure
Log on to the OMS console.
In the left-side navigation pane, choose O&M and Monitoring > Components.
On the Components page, click the JDBCWriter tab.
On the JDBCWriter page, search for the JDBCWriter that you want to delete by its name or server IP address. You can also perform a fuzzy search by migration project name or ID.
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 JDBCWriter that you want to delete, and then select Delete.
In the Deletion Confirmation dialog box, enter "delete" to confirm the operation.
Click Delete.
