Re: Varitas Cluster Software + Oracle Clusterware Installation

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...
