How to configure a Linked Server between Amazon RDS for SQL Server and Teradata database
- Amazon RDS for SQL Server can now use Teradata databases as external data sources via linked server configuration, allowing command execution and data reading from remote servers.
- This setup allows connections between Amazon RDS for SQL Server and a Teradata database, whether on AWS or on-premises, using ODBC connectivity.
- Linked servers with Teradata ODBC are supported for specific versions of SQL Server and Teradata Database.
- To activate ODBC_TERADATA on an RDS instance, you can create or use an existing option group based on your RDS DB instance edition.
- The linked server setup involves creating an option group, associating it with your DB instance, and configuring the linked server for Teradata.
- Connection details like server name, Teradata DB instance, login credentials, encryption, SSL mode, and database name are required for setting up the linked server.
- By using stored procedures like sp_addlinkedserver, a linked server between RDS instances running SQL Server and Teradata can be created.
- You can verify the connectivity to the remote data source using queries through the linked server.
- To clean up resources, you can remove linked servers using sp_dropserver, delete RDS instances, and delete associated option groups.
- Configuring a linked server facilitates distributed queries, cross-database reporting, and secure connections between Amazon RDS for SQL Server and Teradata database for effective data integration.
