2.3.6 Adding the Hosts

Building a topology in Fusion Middleware Composer starts with creating a host, which is a physical or virtual machine that can be associated with an Oracle home and domain. A host is defined in the topology by its IP address.

To add the hosts to the topology:

1. Select Edit > Add New Host.
   Alternatively, you can select the Add New Item icon on the toolbar, select Add New Host in the dialog box, and then click OK.
   A new host (host1) is created in the workspace.
2. Select the host object you just created, and define the following attributes for the host:

   Attribute	Description
   ID	Keep the default value, host1. The ID attribute is an identifier that is used to refer to this host from other parts of the topology.
   Address	Enter the listen address for Host host1.
   Credential	This attribute is used to identify the credential in the wallet file that will be used to connect to the host. Click select to select the credential for the host from the wallet file you loaded in Loading a Wallet File. When you click select, a dialog box appears that lists the credentials in the given wallet. If the credential already exists in the wallet, select the appropriate credential from the list and click OK. If the credential does not exist in the wallet, click New to add the host credential to the wallet and to provide an alias for this credential.

3. Repeat this process to add a second host, host2, to the topology.

After you add and define the hosts, your workspace should look similar to the following example:
