Connectivity between the Replication Agent for Informix and the Informix data server is by way of the Informix JDBC driver.
The Informix JDBC driver must be installed on the Replication Agent host machine and the full path name of this driver must be included in the user’s CLASSPATH environment variable before starting a Replication Agent instance.
For more information on configuring the Informix JDBC driver, see the Sybase Replication Agent Installation Guide.
