We are currently testing RSA Authentication Manager 7x as we want to upgrade our existing infrastructure.. RSA Auth Manager 7 uses oracle as there database system. I have installed RSA Authentication Manager 7 on a RHEL 4 ES server. The software it self works fine. Since we make lot of reports useing sql i tried to connect to oracle using sqlplus command. Now i am facing a lot of trouble to make it work. I have attached the screenshots of directory structure of RSA Auth Manager installation and directrory structure of oracle installation within RSA Auth Manager installation and my bashrc file. I have also attached the screenshot of error i am getting. Please consider that i am a total newbie in oracle...
