Use the Cluster GroupsServer tab to examine the server and application contents of various cluster groups. For example: ■ Group testgroup contains two servers WLEvServer-1 and WLEvServer-2 and one application helloworld as Figure 18–1 shows. ■ Group WLEvServer-1 contains one server WLEvServer-1 and no applications. The helloworld application listed under its Applications node belongs to group testgroup, not to server WLEvServer-1. ■ Group WLEvServer-2 contains one server WLEvServer-2 and one application fx. The fx application was deployed to server WLEvServer-2. The helloworld application listed under its Applications node belongs to group testgroup, not to server WLEvServer-2.
