32-bit Oracle Database server is *not* certified on Windows x64

Posting this as my personal reminder to not forget that statement.  Found this out the hard way while attempting to install Oracle Database 11g R2 (32-bit) on Windows 2008 R2.

Oracle Support clearly states:

“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. For the 32-bit Oracle database client, check the certification matrix for more details.”

Actually the Oracle database software installs without an issue.  It is when I created the actual database that I encountered the same repeated errors in my alert.log after startup.

OER 7451 in Load Indicator : Error Code = OSD-04500: illegal option specified
O/S-Error: (OS 1) Incorrect function. !

Searching My Oracle Support points to Doc. ID 1060806.1 which states:

Installed 32-bit Oracle database software on a 64-bit MS Windows OS which is not supported.

Note: For the Database software, you can ONLY install the x64 version on MS Windows (x64).  You can NOT install the 32-bit version Database software on MS Windows (x64)

Install 32-bit Oracle database software only on 32-bit MS Windows OS.

    Woah! I’m really digging the template/theme of this blog.
    It’s simple, yet effective. A lot of times it’s challenging to get
    that “perfect balance” between superb usability and visual appeal.
    I must say that you’ve done a very good job with this. Also, the blog loads
    very quick for me on Internet explorer. Exceptional Blog!
