Hi,
I've been working with a customer for the past several months and they
pretty much refuse to use DNS resolution for the hostnames of the database
servers. I was not bothered by this since I usually use IPs in my
configurations and app configuration was not my concern.
However now I have to install a RAC (11.2) and they insist in using
/etc/hosts aliases instead of DNS. I've done this in my VMs and it works,
but in the install doc it is clearly stated that you need to have a DNS.
I've installed only 11.2.0.1 with /etc/hosts, but I see some 11.2.0.3
clusters working without a DNS (even an exadata!).
So, has anyone faced any issues while confguring an 11.2.0.3.5 RAC
without a DNS?
oh, we have only one SCAN IP (don't get me started...)
Cheers
Alan.-
