How do you determine the linux kernel architecture?
uname -m gives i686 and uname -m gives i686 i386 output in Red Hat Enterprise Linux Server release 5.4 (Tikanga) machine. I need to install oracle database 10g release 2 on this machine So how do i decide if kernel architecture is 32bit or 64bit?
Best Answer
i386 and i686 are both 32-bit.
x86_64 is 64-bit
example for 64 bit:
behrooz@behrooz:~$ uname -a
Linux behrooz 2.6.32-5-amd64 #1 SMP Mon Mar 7 21:35:22 UTC 2011 **x86_64** GNU/Linux
EDIT:
See is my linux ARM 32 or 64 bit? for ARM
