Will my machine run the 64-bit kernel?
The command will return "32" or "64" depending on the capability of the system.
So you have a 32 bit machine and Oracle 10 can only run on a 64 bit machine.
32bit machines can run some 64bit apps but Oracle 10 needs a 64bit machine / OS.
Time to upgrade the hardware.
