How can I upgrade kernel on a Redhat Linux machine

["Chen, Douglas" <Douglas.Chen@xxxxxxxxxx>]

Hi,

 

I have installed a CAD tool and it complains when launched that the kernel and glibc on this Redhat Linux machine is too old and need to be upgraded. I  need help to figure out how to upgrade both of them.

 

This is the current configuration: Redhat Enterprise Linux WS release 4 (Nahant)

                                             Kernel 2.6.9-5.ELsmp

                                             glibc 2.25

 

I need to upgrade at least to Kernel 2.6.9-42.EL and glibc 2.3.4

 

Please kindly let me know where I can download the kernel and glibc and how I can upgrade them. Also, will the kernel upgrade affect the software currently installed and running without problem? Do I need to compile the new kernel?

 

Thank you very much for your assistance in advance.

 

Douglas
