PRVF-5636 : The DNS response time for an unreachable node exceeded 15000 ms on following nodes: host01, host02

I received this error message when I was trying to install 11.2.0.3 grid software on OEL 5.4 32 bit machine. I resolved it as follows:

- Modified /var/named/chroot/etc/named.conf file on DNS server

Changed the entry for zone “.” IN to

{
type hint;
file "/dev/null";
};

- Restarted named service

[root@server1 ~]# service named restart

- Invoked runInstaller again.

[grid@host01 clusterware]$ ./runInstaller

This time I did not get this error.
Hope it helps !!
