It means if i have only VCS(which probebly our mgmt is going for)  i have
option of singel instance not multiple for one database, and i can enjoy
failover of single instance, -------For Multiple instance i should have
oracle Clusterware(which our DBAs) are not ready for ----There is no way i
can have multiple instance without oracle clusterware....Make me right if i
am not...I have to clear this to our mgmt...
