The idea here is to be able to connect to my Database using the service name instead of SID. Here's my tnsnames.ora:

# tnsnames.ora Network Configuration File: C:\Users\jj\Downloads\WINDOWS.X64_193000_db_home\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl.myDomain.int)
    )
  )
  
DB_PBD =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = myServiceName)
    )
  )

And here's my listener.ora:

# listener.ora Network Configuration File: C:\Users\jj\Downloads\WINDOWS.X64_193000_db_home\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\Users\jj\Downloads\WINDOWS.X64_193000_db_home)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\Users\jj\Downloads\WINDOWS.X64_193000_db_home\bin\oraclr19.dll")
    )
   (SID_DESC = 
        (GLOBAL_DBNAME = orcl)
        (ORACLE_HOME = C:\Users\jj\Downloads\WINDOWS.X64_193000_db_home)
        (SID_NAME = orcl)
    )
   (SID_DESC = 
        (GLOBAL_DBNAME = DB_PBD)
        (ORACLE_HOME = C:\Users\jj\Downloads\WINDOWS.X64_193000_db_home)
        (SID_NAME = orcl)
    )   
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

So far, I'm able to establish the connection using ORCL, orcl.myDomain.int and DB_PBD.

However, when I try to connect to it using myServiceName which is the SERVICE_NAME of the entry DB_PBD, I get the following error:

TNS-12514: TNS:listener does not currently know of service requested in connect descriptor

Is there something wrong with the way myServiceName is defined?

EDIT: When I viewed my service list in my database, I didn't find myServiceName:

SQL> select name from V$SERVICES;

    NAME
    ----------------------------------------------------------------
    orclXDB
    SYS$BACKGROUND
    orcl.myDomain.int
    SYS$USERS
    orclpdb

Should I add it here as well?

  • How exactly did you define/create service? – Joe Sep 25 '20 at 07:33
  • I just added another entry in my tnsnames.ora and named the field SERVICE_NAME `myServiceName`. – Jesse James Sep 25 '20 at 07:36
  • All entries in your tnsnames are service names and no SID's.You need to use dbms_service package to create and start service or netmgr on Windows(not sure about unix/linux) – Joe Sep 25 '20 at 07:38
  • Refer this [link](https://oracle-base.com/articles/10g/dbms_service) – Joe Sep 25 '20 at 07:55

    Noticed Oracle home directory your Database version is 19c and on Windows.You can invoke `netmgr` from run/start menu/command prompt or follow the above link. – Joe Sep 25 '20 at 08:24
  • Thank you, your link helped me a lot. – Jesse James Sep 25 '20 at 08:43
  • When dealing with TNS-12514, the _very first_ thing I'd want to see is the output of 'lsnrctl status' and 'lsnrctl services'. That is much more informative than the content of listener.ora. – EdStevens Sep 25 '20 at 12:49
