Replication Agent uses the Java Database Connectivity (JDBC™) protocol for all communications. When connecting to a primary database, Replication Agent connects to the JDBC driver provided by the database vendor.
Replication Agent uses the Sybase JDBC driver (jConnect™ for JDBC) to communicate with all Open Client and Open Server™ applications, such as Replication Server. Each Replication Agent instance uses a single instance of jConnect for JDBC.
While replicating transactions, the Replication Agent maintains connections with both the primary database and the primary Replication Server, and it may occasionally connect to the RSSD of the primary Replication Server to retrieve replication definition data.
