Register a user-built instance hosted on ECS

Last Updated: May 11, 2020

In addition to Relational Database Service (RDS) databases, DMS Enterprise supports various user-built databases that are hosted on Elastic Compute Service (ECS). This topic describes how to register an ECS-hosted database with DMS Enterprise.

Procedure

For basic information required for registering a database instance, see Instance management.

  1. Enter the basic information of an ECS-hosted database instance and click Test Connectivity. There may be an register error because of the sacurity group rules.

  2. Log on to the ECS console and create a security group rule in the inbound direction to grant the DMS server the access to the ECS instance. Set Authorization Objects to the IP address or Classless Inter-Domain Routing (CIDR) block of the DMS server described in the preceding error message.

  3. Repeat step 2 to create a security group rule in the outbound direction. If you create a security group rule only in one direction, the connection still fails.

  4. Click Test Connectivity again. When the connection is successful, save the registered information. Note: There may be a slight delay after you grant the DMS server the access to the ECS instance. We recommend that you retry the connection in the DMS Enterprise console 1 to 3 minutes later.
