Very strange, since there does not exist a 32-bit version of Oracle 9i or 10g for AIX(only of 8i).
Who told you this ? Did you verify it with Oracle ? Also, on AIX, 32-bit software can run on 64-bit OS if i'm not mistaken (as long as the hardware is 64-bit).
Bad idea to go Windows :-) Why not Linux 64-bit ?
