I have an Oracle database on my network which I am able to connect to with Oracle SQL Developer, using hostname, port, username, password and the SID.
I need to connect another application (Quantum Gis), however it uses the Service Name instead of the SID.
Is there any way for me to determine the SERVICE_NAME of the database when I am connected in SQL Developer via the SID?
I do not have access to the server and have no local tnsnames.ora or similar.
This question is related to
oracle
TO FIND ORACLE_SID USE $. oraenv
Check the service name of a database by
sql> show parameter service;
Connect to the server as "system" using SID. Execute this query:
select value from v$parameter where name like '%service_name%';
It worked for me.
With SQL Developer you should also find it without writing any query. Right click on your Connection/Propriety.
You should see the name on the left under something like "connection details" and should look like "Connectionname@servicename", or on the right, under the connection's details.

select sys_context('userenv','service_name') from dual;
It can be executed with a regular user account, no need for sysdba rights
Found here, no DBA : Checking oracle sid and database name
select * from global_name;
Connect to the database with the "system" user, and execute the following command:
show parameter service_name
