On the left side of the screen, there are two boxes. One is labeled “Host:host1” and the other “Host:host2.” On the right side of the screen, there is one box labeled “Oracle Home:home1” and another box labeled “Domain:domain1.” Inside the “Domain:domain1” box, there is a box labeled “Server:server1” and a box labeled “Cluster:cluster1.”
