Replication Agent requires a JDBC driver to connect to an Oracle primary database.
The JDBC driver must be installed and referenced in the CLASSPATH system variable of the Replication Agent host machine. Java uses the contents of the CLASSPATH system variable to identify the search locations for Java classes. For the Oracle JDBC driver, the full path and file name must be included in the CLASSPATH variable, for example:
drive:\<path_name>\ojdbc14.jar
For the version of the JDBC driver that is supported, see the Replication Agent Release Bulletin.
For JDBC connectivity, the TNS Listener process for the Oracle primary data server must be running.
You can find a description of the Replication Agent configuration parameters that must be set in the Replication Agent Installation Guide > Preparing for Installation.
