ORA-12504:TNS:listener was not given the SID in CONNECT_DATA
<p>I'm new to oracle and trying to start a web application using oracle weblogic.
The application works ok but I am consistently having this error: <code>ORA-12504:TNS:listener was not given the SID in CONNECT_DATA</code></p>

<p>I've searched the web for answers and found out that this is a very common issue for newbies like me.
There's something I found from <a href="http://ora-12xyz.com/error/ORA-12504" rel="nofollow">http://ora-12xyz.com/error/ORA-12504</a> which says that the way to solve this problem is by this:</p>

<ul>
<li>Configure DEFAULT_SERVICE parameter in LISTENER.ORA with a valid service name. Reload the listener parameter file using reload []. This should be done by the LISTENER administrator.</li>
</ul>

<p>but I really do not know how or where to set this on the listener.ora file.</p>

<p>Kindly find below my listener.ora</p>

<pre><code># listener.ora Network Configuration File: D:\app\saduarte\product\11.2.0\dbhome_1\network\admin\listener.ora

      (ORACLE_HOME = D:\app\saduarte\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\saduarte\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )

      (ADDRESS = (PROTOCOL = TCP)(HOST = MAN-L3JFGR32.misys.global.ad)(PORT = 1521))
    )
  )
ADR_BASE_LISTENER = D:\app\saduarte

<p>My tnsname.ora is below, in case this is also needed to solve the issue.</p>

<pre><code># tnsnames.ora Network Configuration File: D:\app\saduarte\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =

    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )
TIPLUS2 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = MAN-L3JFGR32.misys.global.ad)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = TIPLUS2)
    )
  )

<p>This is what I get by executing <code>lsnrctl status</code> on cmd:</p>
