database invoked by filename, the CDD will not be updated

  Explanation:  (In  RDO  or  Rdb$INTERPRET)  You  issued  a  data
  definition statement after invoking by file name.

  User Action:  This is a warning.  You can roll back  and  invoke
  the  database  by  specifying  the path name.  This ensures that
  data definitions are updated both in the data dictionary and  in
  the database itself.
