Configure transport chains

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.

Ensure that a port is available for the new transport chain. If set up a shared port, :

• Use wsadmin commands to create your transport chain.

• Verify all channels sharing that port have the same discrimination weight assigned to them.

 

Overview

We need to configure transport chains to provide networking services to such functions as...

• Service integration bus
• WebSphere Secure Caching Proxy
• high availability manager core group bridge service.

You can either use the console or wsadmin commands to create a transport chain. If you use the console...

 

Procedure

1. In the console, click...

   Servers | Application servers | server

   ...and then select one of the following options, depending on the type of chain you are creating:

   • Under...

     SIP Container Settings

     ...click...

     SIP container transport chains

   • Under...

     Web container settings

     ...click...

     Web container transport chains

   • Under...

     Server messaging

     ...click either...

     Messaging engine inbound transports

     ...or...

     WebSphere MQ link inbound transports

2. 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 is 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.

     If you are configuring a chain that contains a TCP channel, the wizard displays a list of already configured TCP channels and a list of ports that these other TCP channels are not using. You must select one of the ports that none of the other TCP channels are using.

     Similarly, if you are configuring a transport chain that contains a UDP channel, the wizard displays a list of already configured UDP channels and a list of ports that these other UDP channels are not using. You must select one of the ports that none of the other UDP channels are using.

   When you click Finish, the new transport chain is added to the list of defined transport chains on the Transport chain panel.

3. 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:

   1. Click the name of the channel whose settings change.

   2. 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.

   3. Click on Custom properties to set any custom properties that are defined for your system.

4. When you the configuration changes, click OK.

5. Stop the appserver and start it again.

   You must stop the appserver and start it again before your changes take effect.

 

What to do next

Update any routines you have that issue a call to start transports during server startup. When a routine issues a call to start transports during server startup, WAS converts the call to a transport channel call.
