it is not certified. I am getting some library issues when I do the install. If we copy over the libraries from redhat 4, we can work through the install issues. Has anyone used OEM on redhat 5? I do not have a redhat 4 box. This is the only server I have for OEM. I am not allowed to downgrade to redhat 4. I know I won't get support if something goes wrong. It is my only option right now. So has anyone else done this?
