Re: Oracle database HA on VMWare without using RAC

You can also use [Active] DataGuard with Fast-Start Failover (FSFO) if you have already licensed Enterprise Edition, or open-source Pacemaker/Corosync (PCS) Linux HA clustering if you don't fancy licensing anything for HA, provided you're using Oracle Enterprise Linux.

It is surprising how few failure scenarios RAC is capable of remedying, how many failures are caused by clusterware and RAC, and how many more failures can be prevented with true HA solutions.
