Connectivity between the Mirror Replication Agent for Oracle and the Oracle data server is through the Oracle JDBC thin driver.
The Oracle JDBC driver must be installed on the Mirror Replication Agent host machine, and the directory in which this driver is installed must be in the CLASSPATH environment variable.
The TNS Listener Service must be installed and running on the primary database so the Mirror Replication Agent instance can connect to it. For more information, see the Oracle Database Net Services Administrator’s Guide.
