008D999A Object <...> is not a valid DEC DATATRIEVE source.

    Explanation:

    You attempted to ready a CDD$DATABASE object that refers to a
    Oracle CODASYL DBMS database. This is not a valid DEC DATATRIEVE
    source.

    User Action:

    You must use the DEC DATATRIEVE DEFINE DATABASE command to
    specify which subschema of the Oracle CODASYL DBMS database is
    to be used. Once the DEC DATATRIEVE database has been defined,
    you can ready the database directly or you can define domains
    using the DEC DATATRIEVE database.
