A Java™ virtual machine that hosts a catalog service instance requires four ports. Two ports are used for internal use, the third port is used for clients and container shards to communicate with Internet Inter-ORB Protocol (IIOP), and the fourth port is used for Java Management Extensions (JMX) communication.
Catalog service Java virtual machine (JVM) end points
-catalogServiceEndPoints <server:host:port:port,server:host:port:port>With the -catalogServiceEndPoints command line option, you can configure two ports per server. The IIOP ports are configured using the following command line options:
-listenerHost <host_name> -listenerPort <port>When each catalog service JVM is started, specify the complete set of catalog service end points along with a single listener port for that JVM.
Container JVM end points
-listenerHost <host_name> -listenerPort <port>With these command line options, you can specify the host name (important for binding to correct network card) and the port to be specified for that JVM. You can specify the internal port with the -haManagerPort command line argument. However, for the simplest configuration, you can let the run time choose the ports.
