Database link throws ORA-04052 ORA-00604 ORA-12170

 Hi!

When trying deploy an mapping, the database link get this error:

Code: [Select all] [Show/ hide]

ORA-06550: PACKAGE BODY, line 0, column 0:
ORA-04052: error occurred when looking up remote object db1.someC@db1@LOC_db
ORA-00604: error occurred at recursive SQL level 1
ORA-12170: TNS:Connect timeout occurred

			

I can use tnsping towards the db. I can use

Code: [Select all] [Show/ hide]

select * from v$instance@db1@loc_db

			

Any ideas?
Regards
H
