Abstract
A method and system for achieving time-awareness in the highly available, fault-tolerant execution of components in a distributed computing system, without requiring the writer of these components to explicitly write code (such as entity beans or database transactions) to make component state persistent. It is achieved by converting the intrinsically non-deterministic behavior of the distributed system to a deterministic behavior, thus enabling state recovery to be achieved by advantageously efficient checkpoint-replay techniques. The system is deterministic by repeating the execution of the receiving component by processing the messages in the same order as their associated timestamps and time-aware by allowing adjustment of message execution based on time.
