title: ORA-12514: TNS: no listener, and unable to turn on /off lsnrctl
body: <p>I am unable to log in my database, with the message</p>
  
  <blockquote>
    <p>ORA-12514: TNS: no listener</p>
  </blockquote>
  
  <p>I tried to run lsnrctl start / set log_status off, then it loads for a few minute and returns</p>
  
  <blockquote>
    <p>TNS-01153 : Failed to Process the String</p>
  </blockquote>
  
  <p>I also realize that the listener.log file is quite big (4Gb), but since I am unable to clean the file, i am not sure if this is the problem)</p>
