Concurrency Control Monitor for Nested Transactions based on Autonomous Agents
Transaction processing monitors featuring nested transactions are in the core model for mission-critical applications. In this paper, an atomic commit protocol for nested transactions over mobile devices combined with a concurrency control mechanism is introduced. The monitor features a flexible and goal persistent technique dealing with the loss of communication – a latent risk in mobile envir...
متن کاملA Concurrency Control Scheme for Nested Transactions
Locking rules for concurrency control in nested transaction model, in which parent/child parallelism, sibling parallelism, and arbitrary commitment-dependence relationship between transactions are allowed, are presented. The locking rules are based on the lock transformation scheme that never allows the commit deadlock to occur, which could happen by permitting parent/child parallelism. In addi...
متن کاملA concurrency control protocol for nested transactions
Nested transactions[6, 5] provide fine grain atomicity, efficient recovery control, and structural modularity. In distributed environments, they provide a natural and semantically clean way of modelin g computations . However, the characteristics of nested transactions are sufficiently different from those o f traditional single-level transactions that concurrency control for nested transaction...
متن کاملA Theory of Timestamp-Based Concurrency Control for Nested Transactions
We present a rigorous framework for analyzing timestampbased concurrency control and recovery algorithms for nested transactions. We define a local correctness property, local static atomic@, that affords useful modularity. We show that local static atomicity of each object is sufficient to ensure global serializability. We present generalizations of algorithms due to Reed and Herlihy, and show...
متن کاملConcurrency Control Protocol for Nested Transactions in Real-Time Databases
In this paper we consider real-time concurrency control for the nested transaction model. We analyze problems that have pure optimistic and pessimistic approaches. As the solution we propose a hybrid concurrency control algorithm which acts as an optimistic for transactions from different transaction trees and as pessimistic inside a single transaction tree.
