Hello,
I hope my question is not annoying. I work as sysadmin at a 400 users firm and we have around 20 CentOS 4/5 servers and VMs and CentOS is awesome, thank you!
However we have 4 important SAP-servers running RHEL5 and our RHN subscription has unforunately expired and buying it again is not an option right now. Installing CentOS is not an option too, because we'd have to pay for SAP-reinstall.
Has anybody have been in a similar situation and figured out a good way to make "yum update" on RHEL machines to work against CentOS repositories?
Regards Alex

The CentOS repositories are just a YUM repository. Simply add the '.repo' file to your '/etc/yum.repos.d/' folder. You will also need to change the '$releasever' to just '5' as rhel uses 'server5'. I just tested this on a minimal install of RHEL 5.2. Be warned that any updated versions of the RPMs will be overridden by the CentOS RPMs, which did include the kernel. Yum is fairly flexible this way. I am not sure how flexible the rhel update plugin will be if you eventually renew your subscription and try to go back, though.

I always find the sentiments from the management of the original poster interesting. They are serious enough about their business to have spent $$$ on SAP to run the business, then they want to cheap out on the support contract on the OS.
Very short sighted.

You don't know our situation and already have an opinion.
We already spent 400000 Euro for SW licenses this year (and we have only 400 users). And we're an automotive business, so I can understand that management tries to save some money.

woaw .. 400000 euros and you want to spare 4 x 279 euros (basic RHEL subscription) ? Sorry but i don't get the point .. Of course you can normally switch to CentOS but for such business critical application (and the fact that 4 x 279 euros is nothing against SAP price itself) i'd rather continue with RHN subscription .. just my two cents of course

do you understand that if there is ANY issue which could be an OS related problem that even possibly could be caused by mixing builds of RPMs, SAP will not support you, and that e400K investment will be near worthless?

Actually it is trending towards worthless as soon as SAP says "please update package X to the latest version from Red Hat" and you can't do it.

But all the caveats for your $$$ SAP license applies.
