Configuration Requirements for Installing on a Multihomed Computer

You can install your Oracle Fusion Middleware product on a multihomed computer. A multihomed computer is associated with multiple IP addresses. This is typically achieved by having multiple network cards on the computer. Each IP address is associated with a host name; additionally, you can set up aliases for each hostname.

The installer picks up the fully qualified domain name from the first entry in /etc/hosts (on UNIX operating systems) or %SYSTEMROOT%\system32\drivers\etc\hosts (on Windows operating systems) file. So if your file looks like the following (IPv4 example shown below):

127.0.0.1 localhost.localdomain localhost
10.1.1.1 examplehost1.example.com examplehost1
10.2.2.2 examplehost2.example.com examplehost2

examplehost1.example.com would be picked for configuration.
