RAC 12c
Oracle Database 12c
Hi,
we are planning to setup a DR on a RAC instance

Why is RAC one node installed on only one node in the cluster?
If the server from the node(RAC one node crashes), how does relocation takes place?
The RAC One node database will be restarted on another server in pool.
How does the relocation process take place?
WHat is the advantage of having the RAC one node on a cluster node?
Regards,
Joe
