simple install steps for the new kernel with Oracle Linux

I wanted to write up a very short set of instructions on how to configure the new kernel :


- Start with a standard Oracle Linux 5.5 install

(*) If you have an older OL5 then register your system to the Enterprise Linux 5 Latest (x86_64) channel or Enterprise Linux 5 Update 5 installation media copy (x86_64) and Enterprise Linux 5 Update 5 Patch (x86_64) channels.

up2date -u.

The above steps will ensure you are moving up to at least the OL5U5 base.

(*) If you start from RHEL5, you can follow the same steps, starting with how to register your system with ULN. (Specific Howto)


- Install the new packages :

Log into ULN and register the Oracle Linux 5 Latest (x86_64) channel with your system. (click on your registered server -> Manage Subscriptions -> Available Channels)

up2date kernel
up2date oracle-linux or up2date oracle-validated

- Reboot the server and it will come up with the 2.6.32-100.xxx kernel. This will also install a new file /etc/oracle-linux to ensure that the upgrade has succeeded.

You can always boot back into the 2.6.18-xxx based kernel. The grub.conf file will still contain that version.

Comments:

Is there going to be a kernel-xen-2.6.32-100.20.1.el5 for paravirtualized guests under OVM? I don't see one currently.

@Robert: Unbreakable Enterprise Kernel implements pv_ops, so the same kernel can be used on both bare metal and no Oracle VM as a PV guest. Sergio

Great stuff, if only I could get powerpath to work on it... Do you have some friends @ EMC that you could put pressure on so they make a new release for this kernel? thanks and keep up the good work!

@Bruno Send me an email sergio [dot] leunissen [ at ] oracle [ dot ] com. We do have friends at EMC. Sergio

Hello. Can you tell me where to find the source for this kernel? I've hunted round the web site, but I can only find a SRPM for the 2.6.18 kernel. Thanks.

sure - see my previous blog http://blogs.oracle.com/wim/2010/09/git_tree.html points to where the full git tree is located, which isn't just a bunch of patch files but each individual commit both from us and from linus's mainline git tree.
