Linux Version

[Former Member]

Hi All,

I am new to Linux So have some confusions about how to make sure on which version our Linux is running:

When I go to Kenel Information it shows:

created in Linux GNU SLES-7 i686

But my OS team confirmed that we are using Red Hat Linux version 3ES and on market place in PAM I do not see 3ES, I see 3 EL.

So please confirm are these SLES 7 , 3ES and 3EL are same or what is the basic difference between them.

It seems you installed a SuSE Linux kernel on a RedHat machine.

Redhat 3 is ancient and no more supported.

Technically you can also use a new version of CentOS which is technically the same as Redhat - but officially not supported by SAP.

Hi Markus,

As confirmed by Vijay

On Marketplace in PAM Red Hat 3L release is indicating 3 ES also So my this doubt has got clear but I still have confusion for Kernel Compilied on, shown in SAP easy access screen-> system-->status-> kernel information is Linux GNU SLES-7 i686.

What it is indicating, As you said might be we SUSE Kernel on Red hat linux,,,So I think is it possible to install and after installing SUSE kernel works fine on REd hat Machine.

Is these some other way also to make sure this thing.

Hi SHivam

Go to linux command prompt in the server and type like below -

root@server007[~]# cat /etc/redhat-release

You'll get the version like - Red Hat Enterprise Linux ES release 4 (Nahant Update 😎

Hi

following command will give you edition or version of RedHat Linux:

##more /etc/redhat-release

3 ES means means you have ES ( Enterprise server) edition of 3 EL ( Redhat Enterprise Linux 3).

3L --> RHEL 3 = RedHat Enterprise Linux version 3.

RHEL 3 has following editions:

1. Red Hat Enterprise Linux AS 3 ( AS- Advanced Platform)

2. Red Hat Enterprise Linux ES 3 ( ES - Enterprise serer)

3. Red Hat Enterprise Linux WS 3 ( WS - Desktop with Workstation)

4. Red Hat Enterprise Linux Desktop

That means you have 3 ES = Red Hat Enterprise Linux ES 3 ( ES - Enterprise serer)

Hope this helps you.

you said, "created in Linux GNU SLES-7 i686"

Here you are probably talking about SAP kernel compiled on Linux GNU SLES-7 i686.

This information shown in SAP easy access screen-> system-->status-> kernel information.

Looks like you have installed SUSE kernel on RedHat as mentioned by Markus.

Please read Note 936887 - End of maintenance for Linux distributions

Hi Shivam,

SAP kernel is delivered as some executable files which were formed after compiling the programs which were written in languages like C and C++ .

So

Compiled on Linux GNU SLES-7 i686

indicates what (platform, compiler and libraries etc.) was used for compiling those programs so that these executable files were created and delivered to us as part of SAP kernel.

So Linux kernel and SAP kernel are two different things.

Compiled on Linux GNU SLES-7 i686 --> this is about SAP kernel and not the Linux kernel.

Hope this helps you to clear your doubt.
