An instance of the Sybase Replication Agent (a Replication Agent instance) must be created for each primary database from which you want to replicate transactions. Each Replication Agent instance is an independent application with its own configuration and log files, administration port, and connections to the primary database and the primary Replication Server.
Replication Agent instances created for a specific primary database type are referred to in this book as follows:
IBM DB2 Universal Database – Replication Agent for UDB
Informix Dynamic Server – Replication Agent for Informix
Microsoft SQL Server (or SQL Server 2000) – Replication Agent for Microsoft SQL Server
Oracle Server – Replication Agent for Oracle
