hey guys, i wanna update the kernel of thw centos 5.5,to the 2.6.32 version! is there any compatablity issues with stuff like glibc or otheres!
1: Why? Whatever risks exist in changing kernel versions might be obviated by meeting your need another way. Example: Using Fedora 14 or so; RHEL6; or waiting on CentOS 6
2: You are not clear whether you think to replace the CentOS 5.5 kernel (currently 2.6.18-194.26.1.el5) with the kernels.org 2.6.32 version, or do you mean the RHEL6 2.6.32-14.el6.
3: Generally, upgrading ONE part of a MULTI-PART package (i.e. upgrading the kernel, but not the modules, libraries, headers, etc) is on the high-risk list.
=> Whereas CentOS (and this list) thinks more of long-term stability than of bleeding-edge innovation, your curiosity about stepping up to the newest kernel suggests your interests are more in Fedora-land than in RHEL/CentOS land. If Stability is critical, my suggestion is wait for CentOS6.

well,i meant to upgrade to the RHEL kernel and its module ,libraries,headers if found of course but what i meant is there any issue with that i.e no piece of software work with that module or library>>etc,
and the main problem is that i wanna take the RHCE and the best suggested OS is centos not fedora and i wanna run it on my laptop which i tried to do so with the centos 5.5 but there was so many miisings like the wireless card driverr and the display card drivers so i am back to fedora 14 which i am using now and i wanna run oracle databse over linux which has some issues with fedora! such a dillama??? i think i make a clear picture now! any suggestions?

1) Run Fedora 14 on the hardware, and CentOS in a virtualization environment.
or
2) Wait for CentOS 6.
Upgrading the kernel *can* work, but defeats the purpose of running an enterprise OS.
ok,looks great but i wanna know what about the new centos6 support for hardware will it be more oriented to desktops and laptops or what?

It will likely work better with some of the newer hardware, but eventually will run into the same problems CentOS 5 did. It's geared at being a server OS on enterprise hardware more than supporting the latest and greatest consumer level laptop hardware.

I find your statement to not be true at all.
Upstream offers two (2) different Enterprise Level kernels to pick, choose and play with. CentOS only ships one of them.

more explanation plz!

Nothing much ado about nothing to really explain. Just have to search google :-)...
This is the other one [1] the source from upstream. Of which you have to find one built for CentOS like this one [2] exclusively :-). A lot newer and not much laptop support compiled in, who knows it may cut cart wheels. It is built under CentOS.
There is also ELREPO which does a newer kernel also [3].

Oracle does, I know. Does RH?

I see you answered in a later post. Oracle offers their unbreakable kernel or something similar, for their 5.x release. That's a 2.6.32 kernel, which is what I thought you meant.
Thanks for your later clarification.

Yea they sure do in "mERG". There's a difference though one is a Throughput based kernel and one is realtime based with full preemption:
2.6.33.7-rt29.47.el5rt RT based 2.6.18-194.32.1.el5 Throughput based

as mentioned by others, you can get a recent mainline kernel from elrepo.org. you might also get your hardware to work by installing stuff from elrepo, they offer kmods with recent hardware drivers compiled for the regular centos 5 kernel. Including nvidia and ATI drivers (GPU) and many wireless drivers.

Someone suggested Fedora on the hardware and CentOS in a VM.. That works best if you're doing the RHCE..
However, you can also upgrade the kernel and yes, a few things don't always work quite right. Most notably, if I build the stock kernel I usually have to go back and tweak filesystem settings, sometimes some /dev entries don't appear, etc.. Nothing catastrophic, but takes a couple builds to get right. The other option is to grab the prepackaged kernels from some of the devs. They do a great job of packaging the latest, but then you miss out on all that fun of watching your drive LEDs blinking like crazy.
BTW, you can download the RHEL6 trial..
