Hi Shaohui, I think I may have misunderstood what you are trying to do. Please correct me if I am wrong. You have installed RHEL3 on many computers in your company and they are fully functional. But you are trying to setup( or add) OSCAR on your running RHEL3 machines without re-installing their OS (which means that you want to keep all the installed packages (rpms) as well.).
If you intend to keep all the packages in your running RHEL3 adding OSCAR cluster to them, it would be very complicated. This is because normal OSCAR installation needs to have one head node (or possibly more in the multi cluster but we have not really implemented this yet) to take care of all the cluster packages and processes and it requires the client nodes re-imaged with the image that you may setup at the OSCAR installation. So, your most RHEL3 machines for client nodes would be wiped out and be installed with the new RHEL3 which is fully configured for OSCAR cluster. Note, you don't really have to re-install RHEL3 on your head node but we recommend you have a fresh-installed RHEL3 on it. Now that we want to have OSCAR packages installed on the current running RHEL3 machines manually, you have tweak all the configurations for the OSCAR cluster just like the normal OSCAR client nodes by yourself. I think this would be too much work for you and I can not guarantee that this would work. In addition, OSCAR does not have such a feature to setup the client nodes manually YET. BTW, if you are fine with installing OSCAR expecting that all your client nodes would be re-imaged, why don't you try to use RHEL4? I think we don't fully support RHEL3 now and there are some problems to setup OSCAR on it. https://sourceforge.net/mailarchive/message.php?msg_id=36870965 I hope that my comments are not far away from the point.
