Distro Folks, I apologize in advance if this topic has already been discussed, I only now figured out how to join a freelist. In any case, I was stepping through the steps (apologize for the redundant statement) and came to the network configuration. Do we need to configure two networks, i.e. the 192.168.78.1 and 172.16.100.1? The documentation only mentions the former. https://en.wikibooks.org/wiki/RAC_Attack_-_Oracle_Cluster_Database_at_Home/RAC_Attack_12c/VirtualBox_Network_Configuration There are references to the 172 network further in the documentation steps during the Linux Install steps. I'd be happy to include it in there but wanted to check you all beforehand. Cheers, Maaz -- A life yet to be lived...
