Well, it took some time until Oracle Database 11.2.0.3 got finally certified on Oracle Unbreakable Linux 6 (OEL6) and RHEL6 (see the official announcement here). One really interesting change is that effective immediately, Oracle will provide its Red Hat compatible Linux binaries, updates and errata for free http://public-yum.oracle.com
Finally MOS now has been updated as well (please go to the CERTIFICATION tab):
see 1089399.1 "For RHEL6, Oracle will only provide ASMLib software and updates when configured with a kernel distributed by Oracle. Oracle will not provide ASMLib packages for kernels distributed by Red Hat as part of RHEL6"
So if you want to use ASM on RHEL6 you have to install a Oracle Kernel on your RHEL6 system, ääerm, nope. 🙂
