12 Configuring Your Network
Setting Up User Equivalence
Configuring ssh
To configure ssh:
1
On the primary node, log in as root .
2 Go to the Grid binary folder  sshsetup folder and run the following
sshUserSetup.sh script:
sh sshUserSetup.sh -hosts "host1 host2" -user grid
–advanced
sh sshUserSetup.sh -hosts "host1 host2" -user
oracle –advanced
where host1 and host2 are the cluster node names.
After completing step 2, you can configure ssh on other nodes on the grid and
log in as an Oracle user. During login you would not be prompted for a
password.
IP Address and Name Resolution Requirements
For a Cluster Using GNS
To set up an Oracle 11g R2 RAC using Oracle Global Naming Server (GNS)
you require:
• At least two interfaces configured on each node, one for the private IP
address and one for the public IP address.
• A Domain Naming Server (DNS) running in the network for the address
resolution of GNS virtual IP address.
• The DNS entry to establish DNS Lookup to direct DNS resolution of a sub-
domain to the cluster.
• A DHCP service running on the public network for the cluster.
• Sufficient addresses on the DHCP to provide one IP address for each node's
virtual IP, and three IP addresses for the cluster used by SCAN.
