As a primary data server, Microsoft SQL Server interacts with Replication Agent. The Replication Agent identifies and transfers information about data-changing operations or transactions from a Microsoft SQL Server primary database to a primary Replication Server.
A separate Replication Agent instance is required for
each database from which transactions are replicated.
The Replication Agent interacts with the primary Replication Server and with the RSSD of the primary Replication Server, if so configured.
