ATG Service is comprised of several different components. These components can be installed in a number of different combinations.

The suggested set up for Knowledge Manager and Self Service include a combination of agent, management and production servers, as outlined in the diagram below.

All application and database servers are located behind your inside firewall. The HTTP (or Web) server for Self Service is placed between the inner and outer firewall, limiting the number of ports that must be opened externally to a single HTTP port on the outer firewall (access to the HTTP server) and a single port per Self Service servlet engine. By default, this is port 8080 on JBoss, 7001 on WebLogic, 9080 on WebSphere.

Note: The diagram below shows all of the components of Oracle ATG Web Commerce. Your installation may not include all these components.
