  4. Check the disconnected ports.

Solution

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click Service List. Under Database, click RDS. The RDS console is displayed.
  4. On the Instance Management page, click the target DB instance. In the Connection Information area on the Basic Information page, view the VPC where the RDS DB instance is located.
  5. Check whether the RDS DB instance to which distributed transactions are added is in the same VPC as ECS.
