Oracle Database Oracle Clusterware Installation Guide for HP-UX

Configuring SSH or RCP on All Cluster Nodes
1. On the system where you want to run Oracle Universal Installer, log in as the
oracle user.
2. Enter the following commands:
$ exec /usr/bin/ssh-agent $SHELL
$ /usr/bin/ssh-add
3. At the prompts, enter the pass phrase for each key that you generated.
If you have configured SSH correctly, then you can now use the ssh or scp
commands without being prompted for a password or a pass phrase.
4. If you are on a remote terminal, and the local node has only one visual (which is
typical), then use the following syntax to set the DISPLAY environment variable:
Bourne or Korn shell:
$ export DISPLAY=hostname:0
C shell:
$ setenv DISPLAY hostname:0

For example, if you are using the Bourne shell, and if your hostname is node1,
then enter the following command:
$ export DISPLAY=node1:0
5. To test the SSH configuration, enter the following commands from the same
terminal session, testing the configuration of each cluster node, where
nodename1, nodename2, and so on, are the names of nodes in the cluster:
$ ssh nodename1 date
$ ssh nodename2 date
.
.
.
These commands should display the date set on each node.
If any node prompts for a password or pass phrase, then verify that the
~/.ssh/authorized_keys file on that node contains the correct public keys.
If you are using a remote client to connect to the local node, and you see a message
similar to "Warning: No xauth data; using fake authentication data for X11
forwarding," then this means that your authorized keys file is configured correctly,
but your ssh configuration has X11 forwarding enabled. To correct this issue,
proceed to step 6.
