The VIP addresses cannot be on a different domain name from the actual
node name. For instance, using your own node names, these VIP names
would be ok:
pictureupdat1-vip.midpa.as.pacd.local
pictureupdat2-vip.midpa.as.pacd.local
But these would not:
pictureupdat1.vip.midpa.as.pacd.local
pictureupdat2.vip.midpa.as.pacd.local
But the cluster interconnect and, if you use Ethernet based storage
(i.e. NFS, dNFS, iSCSI or FCoE) the storage interface name can both be
on a different domain name (that is, if you bother to configure a DNS
name for these interfaces). I'm not sure if the SCAN addresses need to
be on the same domain or not?
Also, you obviously need a DNS server who can resolve the .local
domain. Or use Grid Naming Service (GNS).
If you're interested, I can send you a complete documentation on how I
installed and configured 11gR2 RAC on RedHat Linux 5 x86_64.
Have fun,
David
