For a multi-host environment, you need to build and define a WebLogic domain, which typically includes an Administration Server and a cluster of Managed Servers.
Building the WebLogic domain includes the following steps:
Add and Define a Domain
Before you define the servers in the topology, add and define the domain. To define a domain, you must provide the absolute path to the domain home location on a given host.
Add and Define a Cluster
Before you can add Managed Servers to the domain, you must add and define the cluster where the Managed Servers are running.
Add and Define the Managed Servers
After you have created and defined the domain and a cluster in your topology, assign the Managed Servers to the cluster in the domain.
