sorry didn't see your reply until today.  Yes, you need to create the link and fill in your db name, username and password
Note, the db name (tns alias) is in quotes, the linkname, username and password are not

create database link DBLINK_TO_B
connect to YOUR_B_USER
identifed by YOUR_B_PASSWORD
using 'YOUR_B_DATABASE';
