In Oracle 11g release 2, Oracle introduced a new product Oracle Real Application Clusters One Node (Oracle RAC One Node)

This product is an Oracle RAC' s instance but executed in one single node. May be run on different physical servers, not only one (this is common) but a database instance is running only on the same node  simultaneously  (* but we'll see later that this is not completely true).
