Oracle : Ошибка ORA-28515

"cannot get external object definitions from %s"
*Cause: ORACLE was unable to retrieve definitions of distributed external
procedures or remote libraries registered for the non-Oracle system
instance, probably because the underlying data dictionary table
does not exist or is malformed.
*Action: Verify that the ORACLE server's Heterogeneous Services
data dictionary was installed correctly. If the Heterogeneous
Services data dictionary is not installed, execute the CATHS.SQL
script in the $ORACLE_HOME/rdbms/admin directory.
