Oracle 11gR2 - Dynamic Registration Database version: Oracle 11gR2
We want to use DYNAMIC_REGISTRATION_LISTENER parameter with off option.
Our listener.ora file like this:
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )



SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
      (SID_NAME = oracle)
    )
  )


ADR_BASE_LISTENER = /u01/app/oracle

DYNAMIC_REGISTRATION_LISTENER = OFF

But when we use this parameter, our web service request cannot connect to the database.
SQL&gt; SELECT dbms_xdb.gethttpport FROM dual;

GETHTTPPORT
-----------
       3010

Without this parameter:
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost.localdomain)(PORT=1521)))

We need to use this parameter. Web services also need to be connected. How is that possible?
I could not find any clear solution.
Best regards,
why do you &quot;need&quot; to use this parameter?  I suspect yet another x-y question - that you are asking the wrong question to solve the wrong problem. Alternatively, why can't you just add the necessary entry to the listener configuration?
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=3010))(Presentation=HTTP)(Session=RAW))
    )
  )
