title: The listener supports no services
body: <p>I installed Oracle Database 11gR2 as well as Oracle Grid Infrastructure on a Linux box, then I created the <code>orcl</code> database.</p>
  
  <p>I have always been able to connect to my database using SQL*Plus or OEM. But lately, I'm facing an issue when typing the command <code>lsnrctl status</code>, and so I'm not able to connect to the database.</p>
  
  <p>My <code>listener.ora</code> file:</p>
  
  <pre><code># listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/grid/network/admin/listener.ora
  # Generated by Oracle configuration tools.
  LISTENER =
    (DESCRIPTION_LIST =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
        (ADDRESS = (PROTOCOL = TCP)(HOST = pc.company.com)(PORT = 1521))
      )
    )
  ADR_BASE_LISTENER = /u01/app/oracle
  </code></pre>
  
  <p>My tnsnames.ora file :</p>
  
  <pre><code># tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
  # Generated by Oracle configuration tools.
  
  ORCL =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = pc.company.com)(PORT = 1521))
      (CONNECT_DATA =
        (SERVER = DEDICATED)
        (SERVICE_NAME = orcl.example.com)
      )
    )
  </code></pre>
  
  <p>When typing <code>lsnrctl status</code>, I get the following :</p>
  
  <pre><code>LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 21-JUL-2014 03:35:48

  <hr>
  
  <p>When typing <code>sqlplus / as sysdba</code> then <code>startup</code>, I get this :</p>

  <p>And the <code>srvctl start database</code> command fails to start the database up too.</p>
  
  <p>My <code>oratab</code> file is the following :</p>
