Crear conectividad dentro del cluster
En cada nodo en el raiz del home de Oracle, usando usuario Oracle. Los mismos pasos para rsa
Generamos primero en el nodo 1
[oracle@Host1]$ ssh-keygen -t dsa
(todo por defecto)
Generating public/private dsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_dsa):
Created directory '/home/oracle/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_dsa.
Your public key has been saved in /home/oracle/.ssh/id_dsa.pub.
The key fingerprint is:
5d:8c:42:97:eb:42:ae:52:52:e9:59:20:2a:d3:6f:59 oracle@Host1.dbsconsult.com
2.- Para transferirlas
The public key on each node is copied to both nodes. Execute the following on each node.

En el nodo 2
[oracle@Host2]$ ssh Host1 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
The authenticity of host 'Host1 (192.168.0.184)' can't be established.
RSA key fingerprint is 00:d9:70:08:bc:fd:b5:e4:e3:df:a3:c7:d8:46:1e:a5.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'Host1,192.168.0.184' (RSA) to the list of known hosts.

Comprobación de la conectividad
- Ejecutar el comando:
./cluvfy comp nodecon -n Host1,Host2
Verifying node connectivity
Checking node connectivity...
Checking hosts config file...
Verification of the hosts config file successful
Node connectivity passed for subnet "172.21.54.0" with node(s) Host2,Host1
TCP connectivity check passed for subnet "172.21.54.0"
Node connectivity passed for subnet "10.10.10.0" with node(s) Host2,Host1
TCP connectivity check passed for subnet "10.10.10.0"
Interfaces found on subnet "172.21.54.0" that are likely candidates for VIP are:
Host2 eth0:172.21.54.31
Host1 eth0:172.21.54.30
Interfaces found on subnet "10.10.10.0" that are likely candidates for a private interconnect are:
Host2 eth1:10.10.10.31
Host1 eth1:10.10.10.30
Node connectivity check passed
Verification of node connectivity was successful.
Thx. Good Job¡¡¡
