Abstract: The text analysed the question of traditionary Unix on realtime application and discussed the Unix realtime characteristic and dispatch stratagem. Adopted principle is append a database which has a realtime function of base on traditionary Unix. It also expatiated the dispatch stratagem of realtime I/O, memory manage, course attemper, clock and timer etc.
