DNS Configuration for 11g R2 Grid installation


Friends,

As I said earlier I was not in touch with blog / other forums due to business reason.. now I got little time touch base with you all.. 

I am back to oracle forums and my blog.. there are up coming oracle events , post I am going to share with you guys.. 

Thank you all..


NOW I want to share DNS configuration in my 11g R2 vmware 10 workstation..  This would be high level configuration between your vm.. 

Pre-Request for DNS configuration in VMware

I am going to share 2 node RAC configuration for DNS in RHEL 5.10.. So I have 2 guest vm and here is my configuration below..

Public IP
192.168.1.8
192.168.1.10
VIP
192.168.1.11
192.168.1.13
Private IP
192.168.1.20
192.168.1.30
DNS
192.168.1.10
192.168.1.8

Once you have VM with above configuration you need to make below configuration for DNS. 

1. /etc/hosts - 
2. /etc/resolve.conf 
3. /var/named/chroot/etc/named.conf
4. /var/named/chroot/var/named/<>.zone





















As I said, All I did DNS configuration by using above configuration and please make sure you should have this changes in your all nodes. 

















Note: I post above details from my techlab system for 11g Grid installation in test machine.. If you don't have DNS domain server then you can try for DNS file configuration. 

Please feel free to reach me for questions.. 

thank you all, Babu
