2.3.3 Example of Building a Topology File

To start building a topology file, use the graphical tools to add and define the hosts and components in the workspace. You can then assign the components to the appropriate hosts.

This topic shows an example of the tasks required to create a topology file using Fusion Middleware Composer. Specifically, this example provides step-by-step instructions to create a topology for the Fusion Middleware multi-host environment shown in Figure 2-3.

This topology contains two hosts (APPHOST1 and APPHOST2). APPHOST1 contains the WebLogic Administration Server, a singe machine, and a single Managed Server, while APPHOST2 contains a second machine and second Managed Server. A cluster is shown encompassing both Managed Servers across both APPHOST1 and APPHOST2.
