Enable WAS to use an intermediary node for Web services transactions

 

You can use intermediary nodes with Web Services Atomic Transactions or Web Services Business Activities to support the exchange of associated requests across firewalls and outside the WAS domain. You configure WAS to use an intermediary node by specifying the HTTP or HTTPS protocol prefix for the node, in each server that is accessed through the intermediary. Configure the intermediary node to use, and ensure that you know the address or addresses of the intermediary node to map to servers in your WAS configuration.

 

Procedure

  1. In the console, click Servers > Application Servers > server > [Container Services] Transaction Service.

  2. Type the prefix for the intermediary node in the HTTP proxy prefix or HTTPS proxy prefix field. This prefix is the intermediary node address that maps to this server. The HTTPS prefix is used if WAS security is enabled and protocol security is enabled for the transaction service; otherwise the HTTP prefix is used.

    If you are using an HTTP server to route messages through a Proxy Server for WAS, the prefix applies to the HTTP server.

  3. Save your changes to the master configuration.

  4. Repeat the previous steps for each server that is accessed through the intermediary node.

  5. Restart the servers.
