I have questions about the OES SP2 rug patch process.

What is the best recommended procedure for installing OES-channel patches?

I see some of the patches are labeled suggested and some are labeled
urgent. Some are labeled feature.

I have two kinds of servers(any difference on how I would apply patches):

1. Replica servers edir

2. Cluster servers edir
I noticed some of the patches are cluster specific.

Question about Linux Kernel Security patches. Do these kernel security
patches install like the other patches or are there additional patches.
YAST is mentioned in the message box when you go to install. Is there
another step necessary that needs to be done within YAST. Does the
kernel need to be re-compiled, etc? This is confusing to me.

Any tids or directions to the proper way to install these patches?
