ORA-12514 when trying to connect to the database using SERVICE

Question

Hi,
Version 10204
In a single instance database i would like to create new SERVICEs in order to use them later with Resource Manager.
The instance name is DWH.
I run the following commands:
I added to the tnsnames.ora file the following input:
XYZ =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxx)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XYZ)
As SYSDBA i execute:
> exec DBMS_SERVICE.CREATE_SERVICE('xyz','xyz');
PL/SQL procedure successfully completed.
> exec DBMS_SERVICE.START_SERVICE('xyz');
PL/SQL procedure successfully completed.
But when i tried to connect to the instance:
sqlplus ac/ac@xyzSQL*Plus: Release 10.2.0.4.0 - Production on Sat Nov 1 14:44:43 2008
Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
When i am trying to connect , not via the service , its successed:
sqlplus ac/ac@dwh
SQL*Plus: Release 10.2.0.4.0 - Production on Sat Nov 1 14:45:07 2008
Copyright (c) 1982, 2007, Oracle. All Rights Reserved.
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
Could you please help to understand why its failed to connect via SERVICE ?
Thanks

Answer 1

You told us.
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
I ask some questions, you set alias for listener port (no default) + local_listener parameter, don't you?
If you did....
Please check by .....
lsnrctl status
lsnrctl service
Let me show my example:
About 1522 (no default port)
SQL> show parameter local_listener
NAME TYPE VALUE
local_listener string ALIASLISTENER
- check tnsnames.ora file in the same location listener.ora file.
$ cat tnsnames.ora
ALIASLISTENER=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost )(PORT = 1522))
- About create new service
SQL> show parameter service_names
NAME TYPE VALUE
service_names string db
SQL> exec DBMS_SERVICE.CREATE_SERVICE('xyz','xyz');
PL/SQL procedure successfully completed.
SQL> exec DBMS_SERVICE.START_SERVICE('xyz');
PL/SQL procedure successfully completed.
SQL> show parameter service_names
NAME TYPE VALUE
service_names string xyz
