  <p>user name and password are correct(I am able to connect using sqldeveloper). I have granted <code>dba</code> access to <code>n_data</code>. All the environment variables are set (I ran <code>oracle_env.sh</code> before running <code>env</code> ). So what might be the problem? I am running oracle on debian.</p>
