in a cluster.

Configuring a DNS Server

To configure changes on a DNS server for an Oracle 11g R2 cluster using a DNS

(without GNS):

Configure SCAN NAME resolution on DNS server. In the DNS, create a

name resolution entry for the GNS virtual IP address in the forward Lookup

file. For example:

scancluster IN A 192.0.2.1

IN A 192.0.2.2

IN A 192.0.2.3

Where

scancluster

is the SCAN NAME provided during grid installation.

NOTE:

The SCAN IP address must be routable and must be in public range.
