We have been running the -55 kernel for a long time on our Oracle servers, there is one issue for us known, which is a memory leak in the kernel in conjunction with HP management agents, but otherwise -55 has been ok for us. But there have been plenty of fixes in newer kernels, but also traps. When we did try to upgrade we ran into kernel panics which got triggered by network drivers and we rolled back.

You will find the packages for your kernel on oss.oracle.com. The news section has the list of changes/bugs fixed. asmlib also has some updates. You can review the fixes to see whether an upgrade is warranted. For all other qs, ping Oracle support and/or Red Hat support.

There has been talks around upgrading Oracle to 10.2.0.4 for some time but the client has not been willing to move on it. I am looking for some professional insight on what can be upgraded vs what should be upgraded, just doing the OCFS2 and ASM vs both these as well as the RDBMS. Also the HBA drivers would need to be upgraded. Any info or opinions would be greatly appreciated. Any additional info needed please do not hesitate to ask. Thanks
