I am not a network person but shouldn’t you have both a primary and a secondary
DNS server so that if the primary DNS server undergoes maintenance all the
applications obtain DNS from the secondary server? Maintenance to your primary
DNS server should not prevent host name resolution via DNS.

Not sure why you don’t want to put the entries in /etc/hosts for a few servers
if that helps reduce any interruption to service

Hello,

Our infrastructure team mentioned hard coding the application/database servers
in /etc/hosts so it can resolve the name and won't lose connectivity when DNS
is unavailable. This is not my preferred method but wanted to see what others
thought.

I'm curious to hear if others have experienced this issue and how they manage
dealing with DNS server maintenance/reboots for their Oracle environments
(E-Business and/or Database)?

Thanks,

Alfredo
