Reviewing recovery-management under real-time requirements in distributed systems

Abstract

Dependencies between computations may lead to unpredictable behaviour of the commit/abort protocols possibly contradicting given real-time requirements. Moreover, it is even possible that the protocols do not terminate. By using redundant dependency storing and by restricting concurrency without isolating computations from each other efficient commit/abort protocols can be provided. Obviously, there exists an alternative to the isolation of computations in distributed real-time systems which allows more concurrency between computations.<>
