I created database link between 2 instances and the message says database link created..but I could not describe or select any tables from the remote database..

here is my commands

drop database link aaa;

create public  database LINK aaa CONNECT TO scott IDENTIFIED BY tiger USING 'mydb' ;

select * from table1@mydb

ORA -12154 TNS could not resolve service name .. but the same db is in tnsnames.ora and it works when  I do sqlplus..
sqlplus scott/tiger@mydb

Can you guys figure out what is wrong here..
