On Metalink one could find the following:
Certify - Product Version and Other Selections: Oracle Database - Enterprise Edition On Microsoft Windows 2003 (AMD64/EM64T)
"Running 32-bit applications on a 64-bit operating system is generally referred to as "Compatibility-Mode" by many AMD64/EM64T hardware vendors. Irrespective of this terminology, 32-bit Oracle Database server is *not* certified on Windows x64."
I haven't given 32-bit software a try on the x86-64 OS be it Microsoft
Windows, RHEL or OEL.
That certification note was sufficient for me. Have I seen the x86 Oracle database server software deployed on an x86-64 server OS? Yes. It worked. But its not supportable.
