Oracle RAC One Node is an option to the Oracle Database Enterprise Edition and licensed based upon the number of CPU’s in the server on which it is installed. Current list price is $10,000 per CPU (Check price list). Unlike the Oracle RAC feature, Oracle RAC One Node is not available with the Oracle Standard Edition. Oracle RAC One Node licensing also includes the 10-day rule, allowing a database to relocate to another node for up to 10 days per year, without incurring additional licensing fees. This is most often used in the case of failover, or for planned maintenance and upgrading. Only one node in the cluster can be used for the 10-day rule.
