Consider fixing the listener ports that you
configured.
For an application server, click Servers > Application
servers > server_name. Under Communications, click Ports.
The Ports panel is displayed for the specified server.
For a
node agent, go to System administration > Node agents > node_name.
Under Additional properties, click Ports. The Ports panel for
the node agent and deployment manager already are fixed, but you might
consider reassigning the ports. For the deployment manager, click System
Administration > Deployment manager. Under Additional properties,
click Ports.
The Object Request Broker (ORB) on WebSphere
Application Server uses a listener port for Remote Method Invocation
over the Internet Inter-ORB Protocol (RMI/IIOP) communications, and
is statically specified using configuration dialogs or during migration. The ORB_LISTENER_ADDRESS
and the BOOTSTRAP_ADDRESS must specify the same port. If you
are working with a firewall, you must specify a static port for the
ORB listener and open that port on the firewall so that communication
can pass through the specified port. The endPoint property for setting
the ORB listener port is: ORB_LISTENER_ADDRESS.

In the
WebSphere Application Server Network Deployment environment, the ORB_LISTENER_ADDRESS
end point is specified on the node agent. The location service daemon
resides on the node agent and piggybacks onto the ORB listener port,
which results in needing the port fixed. Also, you must add the ORB_LISTENER_ADDRESS
to the other application servers to set their ORB listener port. Each
ORB has a distinct listener port. In WebSphere Application Server
Network Deployment, you must specify a different listener port. For
example, you might specify the following ports:
- Node agent: ORB_LISTENER_ADDRESS=9000
- Server1: ORB_LISTENER_ADDRESS=9811
- Server2: ORB_LISTENER_ADDRESS=9812

Federated
servers can run without the node agent running. When ORB_LISTENER_ADDRESS
is set to a value of zero (0) or greater, the server does not depend
on the location service daemon to redirect connections to the server.
When you set ORB_LISTENER_ADDRESS, all object references in the namespace
specify the connection to the server, not the location service daemon.
When the server is running without the node agent, all applications
must be accessed through the name server that runs on the application
server. The client must change the Java Naming Directory Interface
(JNDI) reference to use the host and port of the application server.
Table 1.
ORB_LISTENER_ADDRESS |
|
value = 0 |
The server starts
on any available port and does not use the location service daemon. |
value > 0 |
The server starts
on the port that is specified by the value you enter. The location
service daemon is not used. |
Note: Work load management might not work without the node
agent running.
Complete the following steps
using the administrative console to specify the ORB_LISTENER_ADDRESS
port or ports.
Complete
the following steps for the node agent and the deployment manager.
- Click Servers > Application Servers > server_name.
Under Communications, click Ports > New.
- Select ORB_LISTENER_ADDRESS from the Port
name field in the Configuration panel.
Enter the IP address, the fully
qualified Domain Name System (DNS) host name, or the DNS host name
by itself in the Host field. For example, if the
host name is myhost, the fully qualified DNS name can be myhost.myco.com and
the IP address can be 155.123.88.201.
Enter the IP address or "*" in the Host field.
For example the IP address can be 155.123.88.201. Important: DNS host names are not supported for the ORB_LISTENER_ADDRESS
value.
- Enter the port number in the Port field.
The port number specifies the port for which the service is
configured to accept client requests. The port value is used with
the host name. Using the previous example, the port number might be
9000.
