  3. RAC One Node Database Option primarily targets the failover market Option to Oracle Database 11g Release 2 Enterprise Edition $10,000 per processor Eligible for list-to-list upgrade credit when upgrading to full RAC All nodes on which RAC One Node is installed must be licensed for RAC One Node Exception: One spare node for cold failover/Online Database Relocation need not be licensed under the 10-day use rule Example: In a two-node cluster, customers can license RAC One Node on ONE node; 10-day rule applies for spare node RAC One Node capabilities also bundled with RAC Oracle Real Application Clusters One Node High Availability Database Essentials Oracle Database 11g Enterprise Editon Database Oracle Grid Infrastructure Cluster and Storage Management
