how to reference database link without domain name?

Hi, it is the first time I have this kind of problem, I created a new 10g instance yesterday, in one of the schema I need to reference tables in another instance - TEST2, so I created a db link:

create database link ODW.REGRESS.RDBMS.DEV.US.ORACLE.COM
connect to testdb identified by testdb
using 'TEST2';

I swear I can reference the table without domain name in 10g before, like this:

select * from tab1@odw

but not this time, it seems that I have to use the full name:

select * from tab1@ODW.REGRESS.RDBMS.DEV.US.ORACLE.COM

and it seems that if I wan to use tab1@odw, I have to create another db link:

create database link ODW
connect to testdb identified by testdb
using 'TEST2';

anyone has the same problem before?

didnt you see what you called the dblink? you called it as name, then get surprised when you have to reference it by that name

Are you connecting to a server at Oracle? Do you work there? If not, what is the purpose of using a bogus domain name?
