Registers a database instance with Data Management (DMS).

Prerequisites:

You are a DMS administrator or a database administrator (DBA). You can call the ListUsers or GetUser operation to obtain your user role from the RoleIdList parameter that is returned.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
