[oracle@rac1~]chmod 700 .ssh

[oracle@rac1~]cd .ssh

[oracle@rac1~]ssh-keygen -t rsa

[oracle@rac1~]ssh-keygen -t dsa

[oracle@rac1~]cat *.pub > authorized_keys

Then authorized_keys file 2 into one node, then the node does not cover the document following .ssh authorized_keys file;

[oracle@rac2~]scp authorized_keys rac1:/home/oracle/.ssh/keys_dbs
