Creating and using a service using DBMS_SERVICE

Question

Good day all,
System Spec:
Oracle Database 10g 10.2.0.4.0
Red Hat Enterprise Linux Server release 5.3 (Tikanga) 2.6.18 194.11.4.el5 (64-bit)
I'm trying to create a service that an application will use to connect to a single instance called ORADB1.
I've done the following:
EXECUTE DBMS_SERVICE.CREATE_SERVICE('TEST1', 'TEST1')
ALTER SYSTEM SET SERVICE_NAMES=ORADB1, TEST1 SCOPE=BOTH
Connection descriptor (in tnsnames.ora) is: TEST1=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host.mycorp.com)(PORT=1527))(CONNECT_DATA=(SERVICE_NAME=TEST1)))
EXECUTE DBMS_SERVICE.START_SERVICE('TEST1','ORADB1')
tnsping gives me the following result:
TNS Ping Utility for Solaris: Version 10.2.0.4.0 - Production on 26-NOV-2010 11:38:04
Copyright (c) 1997, 2007, Oracle. All rights reserved.
Used parameter files:
/home/user1/network/admin/sqlnet.ora
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host.mycorp.com)(PORT=1527))(CONNECT_DATA=(SERVICE_NAME=TEST1)))
OK (0 msec)
When I try to connect to the service (via TOAD 10.0.0.41) I get: "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"
The DBA has bounced the database and still no joy.
I've got a feeling I'm missing something simple. Can anybody please help me to get this service working ?

Answer 1

You are creating the service twice once with SERVICE_NAMES parameter and once with DBMS_SERVICE.
You just need to set SERVICE_NAMES parameter and update tnsnames.ora:
SQL> alter system set service_names='TESTXE,XE' ;
System altered.and
C:\>tnsping TESTXE

SQL> select name from v$database;

SQL> exitThis works because in my environment XE is using default listener configuration (port 1521 and TCP/IP).
You may need to set instance parameter LOCAL_LISTENER for your listener configuration: http://download.oracle.com/docs/cd/B19306_01/network.102/b14212/listenercfg.htm#sthref1032
