Intermediary nodes are servers that 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.
