1. Add udev permission rules to /etc/udev/rules.d/65-raw-permissions.rules file
2. Add the udev permission rules to the /etc/udev/rules.d/65-raw-permissions.rules file, for example:
# Set permissions of raw bindings to Oracle Clusterware devices
KERNEL=="raw2", OWNER="oracle", GROUP="oinstall", MODE="640"
KERNEL=="raw1", OWNER="root", GROUP="oinstall", MODE="640"
another odd thing is that user equivalency is not persistent
ie, if I log off and log on on node1, if I ssh node2 date it asks for the key password
User equivalence will need to be enabled on any new terminal shell session before attempting to run the OUI. If you log out and log back in to the node you will be performing the Oracle installation from, you must enable user equivalence for the terminal shell session as this is not done by default.
how can you configure persistent user equivalence
