title: error regarding rcu(repository creation utility) installation
body: <p>I'm installing RCU(repository creation utility). I was not able to connect to the database. I have given following details on database connection details:</p>
  
  <p>hostname: localhost
  port: 1521
  service name: XE
  I am using sys as my username. I am using oracle 11g database xe. I am getting the following message:</p>
  
  <pre><code>UNABLE TO CONNECT TO DATABASE WITH DESCRIBED DETAILS CHECK HOSTNAME,PORT AND CHECK IF LISTENER IS UP AND RUNNING
  </code></pre>
  
  <p>I have checked every above detail and my details are right. I have even try to connect with oracle 10g database xe but error was still there. So please if anyone can help me with this problem it would be great.</p>
  
  <p>Thanks,
  Tarneet</p>
