select * from table_name@mydblink.us.acme.com;

Hi
There are 3 types of links i.e., Private, Public and Gloabl.
To create a privaye database link, u need to have create databas link privilege, check by issuing the following st:
Select privilege from role_sys_privs where privilege in ('CREATE DATABASE LINK','CREATE PUBLIC DATABASE LINK');
If I remember well there should be a script for this, by default. Anyhow, after that, issue as
CREATE DATABASE LINK EMPLOYEE.GAZELLE.COM; (this creates a private link using the global database name to the remote EMPLOYEE database) and uses the connected username/password, that is if u r connected as siva/ram, the link establishes a connection to the remote database as siva/ram.
Hope it makes some sense and also check the tnsnames.ora, listener.ora files.
Thank you
Siva Ram
