Can the patching be done in a rolling fashion? That is, can we shutdown node 1, apply the kernel rpm, the ocfs2 rpm, and the oracleasm rpm, then start node 1 and then stop node 2 for the patching, or will we need to stop node 2 before re-starting node 1?I didn't find any doc about it, but I believe you can patch your OS in a rolling fashion manner, since nothing change on version of ASMLib or OCFS2, you will need to update your ASMLib and OCFS2 due kernel support.
Is it actually neccessary to patch the ocfs2 and oracleasm? The rpms available seem to be the same versions of both (i.e 1.4.7-1 for ocfs2 and 2.0.5-1 for oracleasm), except for the kernel version.OCFS2 Kernel Upgrade.
Finally, are there any good links out there for the process? Almost everything I can find is either related to Clusterware (which apparently started in 11) or to installing and configuring ocfs2 and oracleasm. There does not seem to be anything about applying the rpms to an existing install.Here step by step:
