This is a screenshot of the Fusion Middleware Composer graphical user interface that shows two hosts (host1 and host2), an Oracle home (home1), and a domain (domain1) added to the topology. On the left side of the workspace, there are two boxes. One is labeled “Host:host1” and the other “Host:host2.” On the right side of the workspace, there is one box labeled “Oracle Home:home1” and another box labeled “Domain:domain1.”
