Network Configuration for Computers with Multiple Aliases
You must set the ORACLE_HOSTNAME
environment variable to install Oracle Database on a multialias
computer. A multialias computer is one to which multiple aliases resolve.
A computer with multiple aliases is a computer that is registered
with the naming service under a single IP address, but which resolves
multiple aliases to that address. The naming service resolves any
of those aliases to the same computer. Before installing Oracle Database
on such a computer, set the Oracle installation owner environment
variable ORACLE_HOSTNAME
to the computer whose host
name you want to use.
