Installing on a Multihomed Computer

A server with multiple IP addresses is called a multihomed computer. A multihomed computer uses
multiple network cards, with each IP address linked to a distinct host name or an alias.
By default the installer identifies the host name on a multihomed computer by using the
ORACLE_HOSTNAME environment variable. You can set the ORACLE_HOSTNAME environment variable in
the following way.

Bourne, Bash, or Korn shell:
$ ORACLE_HOSTNAME=myhost.us.example.com
$ export ORACLE_HOSTNAME
C shell:
% setenv ORACLE_HOSTNAME myhost.us.example.com
