Since 10g, server rebooting is the designed behavior during a split-brain.

As far as best practices go, private and public interfaces should never be the same, therefore private interconnect should not failover to the public network. I don't think there's an Oracle mechanism for private interconnect failover.

Having two NICs and a virtual name for the private interconnect is probably the best way to go.
