Intermediary nodes allow the exchange of Web Services Atomic
Transaction (WS-AT) and Web Services Business Activity (WS-BA) protocol
messages across firewalls and outside the WebSphere® Application
Server domain. You configure an intermediary node to specify which WebSphere Application servers the node
routes requests to.
Procedure
- Configure the HTTP server
so that it routes WS-AT and WS-BA requests that are targeted at WebSphere Application Server to WebSphere Application Server, rather than
processing them itself.
- Allocate a set of unique virtual
hosts to the HTTP server; one virtual host for each WebSphere Application
Server that you want the HTTP server to communicate with.
- In the HTTP server, map each virtual
host to a WebSphere Application Server. For example,
you might allocate a virtual host name of vhost1 to the HTTP server,
then within the HTTP server, map vhost1 to a WebSphere Application
Server called server1.
Results
You configured the intermediary node ready for use by WebSphere Application Server.
Example
See the associated example subtopic for
details of the configuration XML for IBM® HTTP
server.
What to do next
Configure WebSphere Application Server
to use the intermediary node by specifying, for each server, the appropriate
virtual host of the intermediary node.
