A full or relative data dictionary path name specifying the
    source of the shareable relation definition. If you use a
    relative path name, the current default directory must include
    all the path name segments that precede the relative path name.

    You must invoke the database by path name if you plan to copy
    a shareable relation definition from the dictionary. You
    must specify a CDO path name and refer to a relation that was
    created with CDO. The relation definition that you copy from
    the dictionary must be a simple definition, that is, one that
    contains no nested records, no repeating groups (arrays),
    and no variants. Also, the data types of the individual field
    definitions that make up the dictionary record being copied must
    be compatible with supported Oracle Rdb data types.
