ORA-02019: Verbindungsbeschreibung für Fern-Datenbank nicht gefunden

Englisch ORA-04052 Error

ORA-04052: error occurred when looking up remote object PUBLIC.UITL_PA@ORA-PRODUCTION
Cause: An error has occurred when trying to look up a remote object.
ORA-00604: error occurred at recursive SQL level 1
ORA-02019: connection description for remote database not found

Mostly this error occurs on invalid TNS Service name or the service name might be missing from the tnsnames.ora
When using a DB-LINK take care of your clean TNS Names!
For example:
create public synonym UTIL_PA for UTIL_PA@ORA-PRODUCTION;
is not the same as:
create public synonym UTIL_PA for UTIL_PA@ORA-PRODUCTION.WORLD;

So watch your tnsnames when using packages via db-links.
When using following tnsnames.ora example:
(Host =
(Port = 1521)

then u have to use @ORA-PRODUCTION.WORLD for the db-link statements!
That's it. It's simple but stupid ...
