Limitations of Oracle 9i database (32-bit)

Hi!

Please help me with this one. I am trying to consolidate known limitations and/or repercussions of running an Oracle 9i (9.2.0.7.0) database (32-bit) running on Windows Server 2K3 (also a 32-bit) on top of a 64-bit hardware and so far all I get is the memory usage. Besides not fully utilizing the allocated memory (since the database will only use not more than 2G and the alloted for the hardware is 16G), what other issues should we be expecting?

Thanks a lot!
