title: Oracle database listner.ora configuration is not read during listener startup
body: <p>I have configured following two configuration files of oracle database. </p>
  
  <p><code>/opt/oracle/11.2.0/network/admin/listener.ora</code> to have following values</p>
  
  <pre><code>ADR_BASE_LISTENER = /opt/oracle
  
  
  
  LISTENER_JIPDB =
    (DESCRIPTION_LIST =
            (DESCRIPTION =
                  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1530))
            )
    )
  
  SID_LIST_LSNR_JIPDB =
    (SID_LIST =
      (SID_DESC =
        (GLOBAL_DBNAME = DWJP02T)
        (ORACLE_HOME = /opt/oracle/11.2.0)
        (SID_NAME = DWJP02T)
      )
    )
  </code></pre>
  
  <p>and I have configured <code>/opt/oracle/11.2.0/network/admin/tnsnames.ora</code>
  file to have following values</p>
  
  <pre><code>LISTENER_JIPDB =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain )(PORT = 1530))
      (CONNECT_DATA =
        (SERVER = DEDICATED)
        (SERVICE_NAME = DWJP02T)
      )
    )
  </code></pre>
  
  <p>My question is when i try to start the oracle listner by typing following command, 
  it is opening the DWJP02T SID instance in 1521 port, i don't know how it is getting this port or from where it is reading this port, I have configured to it to read 1530 on the .ora files. </p>
  
  <p>this is the output i get when i start the listner</p>
  
  <pre><code>[ora112@localhost ~]$ lsnrctl start

  <p>Please help me to understand why it is opening database on different port than what i have configred it to start. I restarted the database and the server to see if it will read values from the listner.ora file, but still no luck. </p>
