Hi,

I have a question in creating database link and accessing data from other database. I created a link

create database link dblink connect to scott identified by tiger
using 'test';

and when tried to access the data

select count(*) from emp@dblink

it gives me
ORA-12154: TNS:could not resolve service name

but, when i connect the same user with like this
sqlplus scott/tiger@test it works fine.


Can anyone tell me what the problem is?

Thanks,
Srilatha

You did not mention that , both databases are in the same computer or not.

If your databases are in two different computers this error can occur due to tnames.ora/sqlnet.ora configuration.
