you havent set up ssh and rsh to not ask for passwords then, you must do that which are part of the installation instructions

[muzammil.dba]

I configure ssh like that, is it correct ???

TWO NODES
$/home/oracle
mkdir .ssh
chmod 777 .ssh
ssh-keygen -t rsa
ssh-keygen -t dsa

SINGLE NODE
ssh rac1 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
ssh rac1 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
ssh rac2 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
ssh rac2 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
scp authorized_keys rac2:/home/oracle/.ssh
scp known_hosts rac2:/home/oracle/.ssh

plz. see the steps, & reply me soon.

Regards,
Muz
