How to install Oracle 12c with alias not based on hostname

HI,

I would like to know if there is a solution which allows to deploy an Oracle RAC 12c (12.1.0.2) configuration with the IP aliases not fully based on the hostname.

As example, our DNS configuration is defined as below :

==> Hostname : pr-oradb1-ipl

==> OAM alias  (Platform Management): pr-oradb1-oam

==> TRF alias - Public IP : pr-oradb1-trf;

==> TRF VIP alias - VIP Public IP: pr-oradb1-viptrf

==> Private alias for private VLAN 1: pr-oradb1-racpri1;

==> Private alias for private VLAN 2: pr-oradb1-racpri2;

==> SCAN TRF alias : pr-oradb1-scantrf;

Based on that IP Alias configuration, we get an error during the installation : "INS-40937".

I know it should be possible ...
