At any time during the execution of the precompiler or the RCI run-time, if a Host / Port combination is required, the information requested is the HOST address of the RCI/JDBC server and the PORT that the server is listening on. The default PORT for the RCI/JDBC server is 7500. For more information on how to configure the RCI/JDBC server, please refer to the CONNX documentation, available online, on the CONNX CD-ROM, and within the CONNX application.
