Good evening (or good morning),
Reading (and writing!) a lot aboud database high availability I have
always wondered how companies set up their DNS server(s) to provide
resilience.
In many cases DNS failures have very negative impact on Oracle
databases: either it's not possible to resolve addresses which is the
same as a denial of service, to runtime problems with existing sessions.
I guess a HA or contingency strategy depends on the DNS server used, and
I dread the majority of companies use M$ AD for this. I can think of
setting up a company "root" DNS with multiple slaves per subdomain in
bind, but that's just me thinking.
Thanks for sharing,
Martin
