You're an SCSA and not sure about what the startup shell is for your Oracle owner UNIX account? You wouldn't know anything about "which sqlplus" or "echo $PATH" or following instructions about using OFA so you would know where your Oracle executables are located? Gee, the install guide is very straightforward, so I don't understand why you don't know how to install Oracle better than the people who wrote the install guide. That's how you said things are for you in another thread.
