There are 2 databases, A and B on 2 machines in production.
We need to export/import these two databases on one single machine.
Production database A has a database link to B.
I would like to create the database link on test system in the database A so that it will point to database B on this same machine. I hope to avoid reports at importing by doing this and to make PL/SQL using the database link working on the test system.
Is possible to create a database link to the localhost database?
