View Full Version : How do I find out fedora relationships to enterprise?

9th December 2007, 12:14 AM
Hi there, I need to play with a product at work that requires 'RedHat Enterprise AS 2.1 with Kernel 2.4'. We use the AIX version of the product but I need to learn how to install it and my only opportunity to do it will be on redhat.

How can I know what version of Fedora to get that will ensure I can install the product? Is there some sort of list that gives the relationship between fedora versions and enterprise versions?

I am amazed that anybody (work wise) is still running the 2.4 kernel, I do not think(? )that RedHat even supports it any more. I THINK that FC1 was the only version that ran the 2.4 kernel and support for it was dropped several years ago.

Edit: http://www.redhat.com/security/updates/errata/

Full support was dropped in 2004, although maintenance support will be available until 2009.

RHEL 3 had a 2.4 kernel IIRC. Must admit it astounds me as well. fwiw there is no real relationship between Fedora and EL. Your best bet would be to go to centos.org and grab 2.1 from there.

I am shocked that Centos still has 2.1, but it does: http://www.centos.org/

RedHat Enterprise AS 2.1 with Kernel 2.4'.

I don't know AS2.1 but the 2.4 kernel is considered ancient history around here.
The only fedora with the 2.4 kernel was Fedora Core 1 (2003). That doesn't
mean it's compatible with another system using the 2.4 kernel. Also you may
have issues installing FC1 on newer hardware.

If you are familiar with one of the virtualizations (qemu/virt-manager, virtiual box,
VMWare free client) then you can probably install FC1 as a guest and try it (this
reduced that hardware issues). Otherwise FC1 is probably your best hope among
fedora distros.

A better idea is to go to the Centos website and load their 2.x version.
You may need to use their yum repo to upgrade to 2.1.

In case you are unaware, RH releases the sources for their enterprise products, but you have to pay to get the binaries (both legal wrt GPL). Centos removes a few RH icons and rebuilds the binaries, and distributes freely.
I wouldn't use Centos on a production server (no support and it undercuts RH biz) but it's a great way to test against a RH clone - almost identical.

Here are some AS2.1 docs.

See here: http://fedoraproject.org/wiki/History
RHEL 2.1 was based on RHL 7.2

Of course, it might not even "require" RHE2.1, when they wrote the
original they couldn't really know what RHE3,4 or 5 would be.
All they did is qualify it on RHE2.1 and just stamped is as
tested and verified on that. It's might work just fine
on a new linux too. Or does it have an obvious problem like
it requires pre-udev devices or something that disappeared in
modern linux?

Wow thanks for all the information. The product I am speaking of is Tivoli Identity Manager 4.6... Which is the current version. IN the release notes, all they mention is that version of Red Hat. It wouldn't surprise me if IBM just found an RHEL that they were comfortable supporting and have stuck with it.

So from what I'm hearing here, it may be worthwhile attempting the current version of Fedora? I know I tried openSUSE (and Solaris 10 x86 with the Solaris media) and the installer couldn't even run. It couldn't find libc.so (and others) on SUSE and couldn't find javalib.so on Solaris...

Well, you might want to use the current version of Centos, it would be more like
RH Enterprise than Fedora is. I'm thinking that IBM may mean that RHE2.1 is
a minimum requirement. They would sure lose a lot of linux customers
if that meant it really didn't work on anything but RHE2.1 (which is pretty old).

I took a look in here:

and found in the Release notes pdf for TIM 4.6
TIM 4.6 Release notes (http://publib.boulder.ibm.com/tividd/td/ITIM/GI11-4212-05/en_US/PDF/im460_rn.pdf)

where it says on page 16:

Linux requirements
Table 5 identifies the RedHat Linux operating system, patches, and minimum
hardware requirements for installation:

Note that it says "minimum" requirements, unless that was specifically for
the hardware I'd think that means you could put it on say Centos 4.5 or
Centos 5.1 (which are the newest ones for 4.x and 5.x)
