Run the ssh utility:
$ ssh -i private-key-file user-name@node-ip-address
where:
• private-key-file is the path to the SSH private key file.
• user-name is the operating system user you want to connect as:
– Connect as the user oracle to perform most operations; this user does not
have root access to the compute node.
– Connect as the user opc to perform operations that require root access to
the compute node, such as backing up or patching; this user can use the
sudo command to gain root access to the compute node
