Servers with multiple network cards

You can run eXtreme Scale processes on a server that has more than one network card.

If a server or client is running on a server that contains more than one network card, then you must specify the network port and host name in your eXtreme Scale configuration to bind to a specified card. If this configuration is not specified, then the eXtreme Scale runtime automatically chooses a network post and host name, which may result in connection failures or slower performance.

When you are setting the host name for eXtreme Scale processes that are embedded in WebSphere® Application Server, you might need to consider the WebSphere Application Server or other stack products in your configuration. For an example, see Technote: Configuring the node agent on one NIC and its application server on another NIC, which is on a different subnet, can lead to ORB errors .

For catalog or container servers, you must set the listener host and listener port in one of the following ways:

In the server properties file.
Command-line parameter on the startOgServer or startXsServer script.

For clients, you cannot use the command line, and must use client properties.
