Re: database link doesn't work!!!

Hi, Sybrand, thanks for your reply.

Still I am not sure how to solve the problem. I have two database in different servers, saying a and b. Now I create a database link in a:

create database link mylink

      connect to user1 identified by user1 using 'b';

After that, I try to do 'select ... from tab1_at_mylink', Then ora-12154 error prompted.
So should I add service name b in the tnsnames.ora of a? Please help!!
