        The DbEnv::get_slice_count() method
        returns the number of slices configured for the environment.
        The number of slices is configured using the 
        set_slice_count DB_CONFIG parameter.
     
         The DbEnv::get_slice_count() method may
         only be called after the environment has been opened.

                exception that encapsulates a non-zero error value on
