Btw, as of March 2012, Oracle Linux provide patches and errata for free via Oracle Public Yum.ASMLib packages are not available trough public Yum for RHEL/OEL6
So today, we (Oracle) provide Oracle ASMLib for Oracle Linux and in particular on the Unbreakable Enterprise Kernel. We did the build/testing/delivery of ASMLib for RHEL until RHEL5 but since RHEL6 decided that it was too much effort for us to also maintain all the build and test >environments for RHEL and we did not have the ability to use the latest kernel features to introduce the Data Integrity features and we didn't want to end up with multiple versions of asmlib as maintained by us. SuSE SLES still builds and comes with the oracleasm module and they do all >the work and RHAT it certainly welcome to do the same. They don't have to rebuild the userspace library, it's really about the kernel module.So, due to political issues ASMLib is obsolete for RHEL6. If you'd like to use all benefits of ASMLib then OEL6 seems better option.
