| ERROR | cannot get external object definitions from string |
| 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 servers 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. |
