The object name representing your database manager instance (or your database) in the directory. The concatenation of this value and the dir_path_name value yields a global name that uniquely identifies the database manager instance or database in the namespace governed by the directory services specified in the dir_type parameter.
This parameter is only meaningful if the dir_path_name parameter is specified.
The total length of the configuration parameters dir_path_name and dir_obj_name must be less than 255 characters.
