Oracle E-Business Suite Release 12 is already certified with the 10gR2 10.2.0.4 database for several platforms. Our Applications Platforms Group continues to certify additional platforms on a regular basis. They have just completed their certification of Oracle E-Business Suite Release 12 versions 12.0.4 and 12.1.1 with Microsoft Windows Server 2003 and 2008 for x64 (64-bit) platforms.
You should review the system requirements from the relevant Oracle Database 10gR2 documentation (Installation Guide, Release Notes, Upgrade Guide) prior to installing the database on these platforms.
These are database-tier only certifications (previously known as "split configurations" in Apps 11i). The application tier must be on a fully-certified Oracle E-Business Suite R12 platform.References
