I read the man pages for Real Application Cluster and they appeared to be lightly reformatted version of the man pages for TruCluster (I can't speak about VMS clustering, I only know Tru64's clustering). TruCluster was definitely interesting, but expensive and fairly esoteric. Most Linux people would just horizontally scale their applications without depending on its features (a filesystem that was shared seamlessly across 8 machines, along with virtual IP address aliasing with fast failover).
