ORA-28520: error initializing heterogeneous data dictionary translations
Cause: ORACLE was unable to retrieve data dictionary translations for the non-Oracle system instance, probably because the underlying data dictionary table does not exist or is formed incorrectly
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. If the connected agent, identified by FDS_CLASS_NAME, requires a custom installation script for the ORACLE server, verify that the script has been run. If both scripts were executed and the error persists, contact the customer support representative of the agent vendor
