A rubber locking device for a bicycle seat bag is composed of a rubber strip which is fastened to the top of the seat bag by a clamp board, two hook bases correspondingly provided at two sides of the seat bag for fastening to the two ends of the rubber strip. To save time, the coredump is allowed to occur contemporaneously with the takeover of the failed filer’s regular, active file service disks by the partner so that the takeover need not await completion of the coredump to begin. The present invention then uses a blue light emitting diode chip that emits light having a wavelength between of 400\u02dc500 nm to emit blue light and uses the blue light emitting diode chip to excite a green phosphor to emit green light having a wavelength of between 490\u02dc560 nm. Plants of the new variety develop well following budding and following the rooting of cuttings. The invention allows controlling a communications network, communications network resources, communications network services and services provided over the communications network significantly faster than prior art implementations.
