As per Oracle, it requires three Linux packages to run ASMLib:

  1. oracleasm - kernel module
  2. oracleasmlib-2.0 - ASMLib libraries
  3. oracleasm-support-2.0 - Admin for ASMLib

This library versions are OS dependent, but my RAC is working fine without the oracleasm kernel module.

 $ rpm -qa | grep 'oracleasm'


$ oracleasm listdisks

Someone can please guide why its running perfectly without having main kernel module?

This question came from our site for professional and enthusiast programmers.

Without knowing what kernel you're running, I can't say for sure, but my guess is that you're running a recent UEK kernel, and it has the kernel module built in.

Linux kernel is: # cat /proc/version Linux version 2.6.39-400.17.1.el6uek.i686 ( (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Fri Feb 22 18:17:46 PST 2013 I want to use tagging to make post appear good but not able to understand how to use, please guide me. – user3134198 Jan 2 '14 at 4:23
Yes, see the 'uek' in the kernel string? That means it's a UEK kernel. (Unbreakable Enterprise Kernel) That's a kernel put together by Oracle, with Oracle's patches and additions, which includes the ASMLib kernel driver. – Mark J. Bobak Jan 2 '14 at 8:17
