Why has Oracle chosen Linux x86-64 as the architecture for the initial configurations?
Oracle is seeing significant end-user demand for Linux x86-64 architectures and is fully committed to developing, advancing and promoting the 64-bit commodity Linux. All new chipsets and servers are now being shipped with x86-64 architecture, thereby offering a much wider hardware selection to end-users than some of the other architectures. Therefore, Oracle has chosen to initially make Oracle Validated Configurations available on Linux x86-64.
