Replication Server interacts with other components of a replication system as either a server or a client.
As a server, Replication Server supports connections from:
Replication Agents, across which database commands are sent from primary databases
Other Replication Servers, thus distributing the processing involved in message delivery and providing a degree of scalability in a replication system
Users or management tools for administration, data server identification, message publication and subscription, and so on
As a client, Replication Server connects to:
A Replication Server System Database (RSSD) which can be on an external Adaptive Server Enterprise database, or the internal embedded RSSD (ERSSD).
A database gateway to connect to the replicate non-ASE database.
