 With this enhancement, you can deploy and run multiple single-instance databases in a single-node cluster without RAC licenses being required.
 
-Please note. This functionality should only be used in non-production environments where the customer does not have RAC licenses.
+Please note. This functionality should only be used on non-production environments, where under BYOL licensing, RAC licenses are not available.
 
-The lack of RAC licenses means that the customer is unable to easily instantiate the DB instance on another DB Server in the ExaDB infrastructure. This means that during maintenance, there will ALWAYS be an outage of the DB service unless the customer moves the service to the DR environment.

 Single Node VM Cluster provides ZERO capability for local failover for either planned or unplanned outages.
 
-For customers who do have a RAC license, but want to run Single Node instances, the preferred mechanism is to use clusters, as outlined in the following deck: SIDB on ExaDB

+Run each single instance database as a singleton workload or PDB in a shared RAC CDB (the preferred way)
+Run each single instance database as a singleton workload or PDB in a dedicated CDB
+Run each single instance database as a two–node cluster, but shut down unnecessary instances
