Resource Dependency Tree
The following steps describe the process of creating a resource dependency
tree. Each step is illustrated by adding information to a sample resource
dependency tree. The sample is for a hypothetical Web Sales Order business
function, which consists of two cluster groups: a database server
(a Windows NT or Windows 2000 application) and a Web server (a
Windows NT or Windows 2000 service).
NOTE: For this example, it is assumed that each cluster group can communicate with the
other even if they are not executing on the same node, for example, by means of an IP
address. With this assumption, one cluster group can fail over to the other node, while the
remaining cluster group continues to execute on its primary node.
1. List each business function that requires a clustered application
or service (Figure 2-5).
