Hi there,

You are talking about ssh key exchange (that allows you not to entrer passwords when connecting from one host to the other) ?

... and many other examples available on the net (just use any search engine)

Cheers,

There are tons of examples out there.  This is the one that I tend to use:

Just search for "ssh without password" and you will get as many examples as you want.

I assume you realize that a secure shell works only for the O/S account, and does not affect a SQL*Plus client session.....  

Also may I strongly encourage your SA to require sudo for privileged accounts.  Membership in the O/S oradba group is usually sufficient for DBAs to work in the $ORACLE_HOME filesystem -- so remote access to user ORACLE adds unnecessary risk.

Here is my opinion
---------------------------------------
you do not have to manually setup passwordless SSH setup. When you install 11gR2 grid infrastructure on one of the screen you see SSH Connectivity button. When this button is clicked it display text box to enter the password and then click setup button. It will set up passwordless SSH connectivity for you. Once setup is done click on test button to make sure its successfull. If it fails then a manual setup is needed.
