The
        Replication Agents for Oracle, Microsoft SQL Server, and IBM DB2 UDB support the use of the
        secure sockets layer (SSL) for connections to and from Replication Agent instances. 
The SSL protocol runs above TCP/IP and below application protocols such as remote method
            invocation (RMI) or Tabular Data Streamâ„¢ (TDS). SSL is supported for connection with the
            execption of the connection to the RSSD.
As a client, a Replication Agent instance can use SSL in connecting to servers, including:
- Replication Server
- Primary data
                    server
The Replication Agent administrator and client applications can use SSL to encrypt
            connections to Replication Agent.
Replication Agent does not support SSL to the RSSD.
Note: The Replication Agent
                connectivity to the RSSD can be disabled. The Replication Agent connectivity to the
                RSSD is only for informational purposes intended to improve the replication
                performance.
