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> SELECT dbms_xdb.gethttpport FROM dual; GETHTTPPORT ----------- 3010 **Without this parameter:** Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost.localdomain)(PORT=1521))) STATUS of the LISTENER ------------------------ Alias LISTENER Version TNSLSNR for Linux: Version 11.2.0.4.0 - Production Start Date 07-FEB-2021 03:21:59 Uptime 0 days 0 hr. 2 min. 51 sec Trace Level off Security ON: Local OS Authentication SNMP OFF Listener Parameter File /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora Listener Log File /u01/app/oracle/diag/tnslsnr/localhost/listener/alert/log.xml Listening Endpoints Summary...

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))) (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=EXTPROC1521))) 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,
