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 

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,
