Relationship with Other System Components

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.
The Oracle replicate database directly, when using ExpressConnect for Oracle.

Replication Server Communication Protocols
Replication Server is an Open Client and Open Server application that uses Sybase Tabular Data Stream™ (TDS) as the underlying communication protocol.
Replication Server User IDs and Permissions
Replication Server requires several different user IDs. Some user IDs are required for other components (or users) to access the Replication Server, and others are required for the Replication Server to have access to other components in a replication system.
Relationship with Replication Agents
While Replication Server is extensible (with customizable function strings and error handling, custom datatype definitions, and translations between datatypes) to meet the needs of replicate data servers, Replication Server support of primary data servers is limited.
