You must open ports to communicate among servers and with
remote servers.
Configuring ports in stand-alone mode
You can configure the necessary ports for servers and clients
in an eXtreme scale deployment by using command-line parameters, property
files or programmatically. Most examples included in the following
sections describe command-line parameters to the startOgServer script.
Equivalent configuration options can also be set in properties files,
using the embedded server API or the client API.
Configuring ports in a WebSphere Application Server environment
WebSphere eXtreme Scale catalog services, container servers
and clients, when running in WebSphere Application Server processes,
utilize ports and services already defined for the process.
