Global Consistent State Maintaining Algorithm in the Strategy of Debugging Real Time Distributed System at Events-Level

摘要

In debugging real time distributed system, the problem of maintaining global consistent state makes the setting breakpoints and single step in traditional debugging unavailable. Based on the events-model distributed debugging technical, this paper proposes a debugging strategy using breakpoint and single step in events-level. Different from the traditional debugging in statements-level, the events-level strategy is focus on the interactive and cooperative behavior of real time distributed system. Meanwhile, this paper proposes an algorithm to guarantee that the state of the system is global consistency each time when the system pauses.
