The Resource_dependencies setting on the Oracle iPlanet Web Server application resource determines the set of IP addresses that Oracle iPlanet Web Server uses. The Port_list setting on the resource determines the list of port numbers that Oracle iPlanet Web Server uses. The fault monitor assumes that the Oracle iPlanet Web Server daemon is listening on all combinations of IP and port. You can configure the server.xml file for the Oracle iPlanet Web Server to listen on different port numbers (in addition to port 80). The fault monitor attempts to probe all such combinations and starts to fail if the Oracle iPlanet Web Server is not listening on a particular IP address-port combination. If the Oracle iPlanet Web Server does not serve all IP address-port combinations, you must break the Oracle iPlanet Web Server into separate instances that do.
