Hi Guys,

I'm trying to install Websphere Application Server on a Linux box ... here are the s/w spec on the box

kernel release 2.6.9-5.EL
red hat enterprice linux AS release 4 (Nahant)

Now the s/w requeirements for Websphere App Server is : Red Hat Enterprise Linux WS/ES/AS for Intel 2.1 2.4 Kernel

Question: can the fact that in current installed kernel version is newer that the required kernel by Websphere App Server make the installation NOT to work?

because when i'm busy installing the s/w it Hangs and does not produce any error logs! any help will be appreciated.

WAS, you need to follow the requirements pretty closely. I'd be willing to bet that this version of WAS is not supported under RHEL4, so don't bother trying. WAS can be pretty difficult by itself without complicating it by installing on unsupported versions.
It's probably a library problem more than just the kernel.
Isn't WAS6 available?

RHEL 4 support was added in WAS6

Hi,

I managed to install Websphere 5.0 (with fixpack 2 and cumulative fix 12) on a CentOS 4.1 (RHEL clone) and it's working without problems. Because of the 2.6 kernel, after you install Websphere, you need to put the following lines in ...AppServer/bin/setupCmdLine.sh somewhere at the beginning of the file:

LD_ASSUME_KERNEL=2.4.9
export LD_ASSUME_KERNEL

if you look in the LaunchPad.sh script from the Websphere CD for Linux, used to install websphere, you will see that this lines are in there.

Right now I'm trying to install Websphere on a SLES 9.2.. and I can tell you that I have some serious compatibility problems :-) Some of them were solved after installing Service Release 8 for IBM Java 1.3.1 (I installed it after I read a thread on a forum regarding compatibility problems with WAS 5.0 and RH 3.0 which were solved in IBM Java SR5 ).

So, basically, if you want to be on the safe side, you should choose a distribution/version officially supported by IBM for WAS 5.0.

Have fun,
George
