Problem in accessing DBlink

Question

Hi,
I have two database running on my local machine..
I logged in one of the database and create DBlink for another database as
Create DATABASE LINK <dbname>
when I tried to access that another database as
select *from <tname>@<dbname>
it giving the error
ERROR at line 1:
ORA-02019: connection description for remote database not found

Answer 1

CREATE DATABASE LINK dblinkname CONNECT TO dblinkschema IDENTIFIED BY dblinkpassword USING 'netservicename';
From the above example, the dblinkname is the database link I am creating. dblinkschema is the schema I want to connect to (if I want specific schema). netservicename is the entry in my TNSNAMES.ora for the target database (which could be the full dbname or anything else I called it)
So I need the dblinkname in my SQL instead of the netservicename:
e.g select * from test_table@dblinkname;
