title: Error code 2 starting OracleDbConsole service
body: <p>I installed Oracle DB 11g, 
  everything was working well, but suddenly process
  <code>OracleDbConsoleorcl</code> didn't start anymore, I try
  manually but it always shows this message:</p>
  
  <pre><code>Windows could not start OracleDbConsoleorcl on
  Local Computer. If this is a non-Microsoft service,
  contact the service vendor, and refer the service
  specific error code 2
  </code></pre>
  
  <p>What should I do??</p>
