title: error: ORA-65096: invalid common user or role name in oracle
body: <p>I just installed <em>Oracle</em>, and it was missing the Scott schema. So i am trying to generate it myself. I got the sql script of Scott schema, but when i try to run the query:</p>
  <pre><code>create user Scott identified by tiger; 
  </code></pre>
  <p>it displays the following error:</p>
  <blockquote>
  <p>ORA-65096: invalid common user or role name in oracle.</p>
  </blockquote>
  <p>Basically it is not allowing me to create a user Scott.</p>
  <p>Why is that, and how can I fix my problem?</p>
