12c Editions :

Keeping customers’ budget and functionality needs in into consideration, Oracle has made available Oracle database 12c in 3 editions :

Oracle Database Enterprise Edition offers unlimited CPU and memory usage (upto the OS maximum), along with Oracle Database 12c’s all features, though almost twenty of them - which include the Database and Multi-Tenant In-Memory technologies — are optional add-ons that must be purchased separately. List prices for the Enterprise Edition start at $90 for a Named User Plus license or $47,500 for a processor license.

Another option is Oracle Database Standard Edition which involves less cost along with less feature set for departmental applications or medium and small-sized businesses. Only on servers with four sockets as their maximum capacity, the Standard Edition can be licensed. A minimum of five licenses is required if in case Named User Plus licensing is utilized.

Oracle Standard Edition One is an entry-level offering that can be used only on servers with up to two sockets. The other primary difference between it and the Standard Edition is that it won’t offer support for automated workload management technologies and Real Application Clusters of Oracle.

The supporting systems include Linux x86-64 and zLinux64, HP-UX Itanium, Oracle Solaris( for both x86 systems and SPARC), zLinux64 and IBM AIX(PPC64).
