A Planning-Based Approach to Failure Recovery in Distributed Systems
Thesis directed by Professor Alexander L. Wolf
Automated failure recovery in distributed systems poses a tough challenge because
of myriad requirements and dependencies among its components. Moreover, failure
scenarios are usually unpredictable so they cannot easily be foreseen. Therefore,
it is not practical to enumerate all possible failure scenarios and a way to recover a
distributed system for each of them. Due to this reason, present failure recovery techniques
are highly manual and have considerable downtime associated with them. In this
dissertation, we have developed a planning-based approach to automated failure recovery
in distributed component-based systems. This approach automates failure recovery
through continuous monitoring of the system. Therefore, an exact system state is always
available with a failure monitor. When a failure is detected the monitor performs
various checks to ensure that it is not a false positive or false negative. A…
