Solution for Oracle Error ORA-02082

ORA-02082: a loopback database link must have a connection qualifier

What triggered the Error:

attempt to create a database link with the same name as the current database.

What should we do to fix it:

a loopback database link needs a trailing qualifier, e.g. MYDB.DEV.US.ORACLE.COM@INST1 - the '@INST1' is the qualifier
