    Run DBCA once again and chose the option to create a script. If you run this create database script you will get more info about your problem.
    It could be that you need to install libaio-xxxxx.rpm.
    It is important that you install all necessary rpm or you will get this sort of problems. Have you checked the installation guide for missing rpm's?
