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.
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.
About 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.
If you use the administrative console, complete the following steps:
Procedure
- In the administrative console, click Servers > Application servers
> server_name, and then select one of the following options, depending
on the type of chain you are creating:
- 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:
When you click Finish, the new transport chain is added to
the list of defined transport chains on the Transport chain panel.
- Click the name of a transport chain to view the configuration settings
that are in effect for the transport channels contained in that chain. To
change any of these settings:
- Click the name of the channel whose settings you need to change.
- Change 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 are defined for your system.
- When you your configuration changes, click OK.
- Stop the application server and start it again.
You
must stop the application server and start it again before your changes take
effect.
