By the way, I have installed oracle8 on linux before. It's no problem .
That's very strange.
And the installation way of oracle8i is very different from oracle8. I download the installation guide from www.oracle.com.
It wil fail if I don't install like that. You have to install it in x-window. And switch to command line for several times ....
I am thinking it ...
That's ok . I just found another way to grant the web client user can run the CGI application to access the database.
