Determining 32bit vs 64bit o/s
 
I am installing oracle version 10.2x and need to determine if I am running 64bit or 32bit.
Here is what I have, but I am unsure what it is telling me.

[oracle@seebs5 bin]$ uname -a
Linux seebs5 2.6.9-5.ELsmp #1 SMP Wed Jan 5 19:30:39 EST 2005 i686 i686 i386 GNU/Linux
[oracle@seebs5 bin]$ uname -i
i386

thanks in advance.

i686 i686 i386

That would be 32 bit, I believe.

Oracle Corp answered me also with the following..hope it helps everyone..tks for the "reply".

Determining 32bit vs. 64bit and what software to download:
There is a key piece of information about any system that you will need to know what to choose:
#uname -a: 2.6.9-5.ELsmp i686

Notice the “i686” near the end of the “uname -a” output? That tells you (beyond any doubt that you are using a 32-bit (aka x86)
Linux OS. That means that the right choice for your question is: “Linux x86”

Just for your information, other “uname -a” and “what to choose” answers are:
x86_64 - Linux x86-64?
ia64 - Linux Itanium
ppc - Linux on Power PC (unusual)
s390x - Linux on an IBM zSeries processor (very unusual)
