A transport chain consists of one or more types of channels, each
of which supports a different type of I/O protocol, such as TCP or HTTP. Network
ports can be shared among all of the channels within a chain. The channel
framework function automatically distributes a request arriving on that port
to the correct I/O protocol channel for processing. To define these channels:
Before you begin
Ensure that a port is available for the new transport chain. If you
need to set up a shared port, you must:
- Use wsadmin commands to create your transport chain.
- Make sure that all channels sharing that port have the same discrimination
weight assigned to them.
Why and when to perform this task
You need to configure transport
chains to provide networking services to such functions as the service integration
bus component of IBM service integration technologies, WebSphere Secure Caching
Proxy, and the high availability manager core group bridge service.
You can either use the administrative console or wsadmin
commands to create a transport chain. To use the administrative console:
Steps for this task
- In the administrative console, click Servers > Application servers
> server_name, and then click on one of the following:
- Under Web container settings, click Web container transport
chains.
- Under Server messaging, click either Messaging engine inbound
transports or WebSphere MQ link inbound transports.
- Click New. The Create New Transport Chain wizard
initializes. During the transport chain creation process, you are asked to:
- Specify a name for the new chain.
- Select a transport chain template
- Select a port, if one is available to which the new transport chain will
be bound. If a port is not available or you want to define a new port, specify
a port name, the host name or IP address for that port, and a valid port number.
When you click Finish, the new transport chain is added to
the list of defined transport chains on the Transport chain panel.
- Click on the transport chain's name to view the configuration settings
that are in effect for the transport channels contained in this chain. To
change any of these settings:
- Click on the channel that requires changes to its settings.
- Make your changes to the configuration settings. Some
of the settings, such as the port number are determined by what is specified
for the transport chain when it is created and cannot be changed.
- Click on Custom properties to set any custom properties
that have been defined for your system.
- When you have made all of your changes, click OK.
- Stop the application server and start it again. You
must stop the application server and start it again before the configuration
changes you made take affect.
