create public database link my_link connect to home_office identified by home using 'j2ee';
Link is created successfully. and i was able to connect to the database. Now when i remove my tnsnames entry for that DB on my work station, the Link doesn't work.
So my question is

i just dont understand this thing. can anyone shed some light on where iam getting it wrong. really appreciate it.
