Abstract: For the speciality of distributed real-time system and the program that is written by distrbuted real-time language DRTC++ based on the on the distributed os kernel DRTK, this paper introduces the design and theorem of DRTDebug, exposes the approach of adjusting the indeterminacy and initiates the model of information collection of real-time execution of distributed system. The model is easy and useful, and can be used in debugging of distributed real-time program directly.
