A single Replication Server connection can support both an ECDA gateway and a Replication Agent, because each of these components connects to the Replication Server on a different thread. If you replicate information both into and out of the same database, having a common connection for both a database gateway and a Replication Agent can make the replication system network topology less resource intensive. On the other hand, because the Replication Agent and the ECDA gateway are two separate servers, it might be more intuitive to have a separate connection for each one.
To share a Replication Server connection between an ECDA gateway and a Replication Agent, you must define the connection to correctly support the replicate database, then configure the Replication Agent appropriately:
In the Replication Server, use the create connection command to define the server_name and database_name for the connection. The server_name value must match a configured service name in the ECDA.
In the Replication Agent, set the value of the rs_source_ds parameter to that server_name, and set the value of the rs_source_db parameter to the desired database_name.
