Locking Based Concurrency Control for Integrated Real-Time Database Systems
نویسندگان
چکیده
In many database applications, incoming transactions are a mixed load of conventional (non real-time) and real-time (typically soft and rm) transactions. In this environment, transactions can even be changed dynamically from non real-time to soft or rm, or from soft to rm deadline transactions according to their execution paths. In this paper we show how lock based approach can handle these situation better than Optimistic Concurrency Control and how we can extend Alternative Version Concurrency Control (AVCC Hon95]) to handle the mixed load ef-ciently for integrated real-time databases systems .

Concurrency Control in Real - Time Database Systems : Optimistic Scheme vs . Two - Phase Locking
The two-phase locking approach widely used for concurrency control in database systems have some inherent disadvantages such as deadlock and unpredictable blocking time. These appear to be serious problems with respect to real-time transaction processing , since in a real-time environment transactions need to meet their time constraints as well as their consistency requirements. Integrated with...
متن کاملExperimental Evaluation of Real-Time Optimistic Concurrency Control Schemes
Due to its potential for a high degree of parallelism, optimistic concurrency control is expected to perform better than two-phase locking when integrated with priority-driven CPU scheduling in real-time database systems. In this paper, we examine the overall effects and the impact of the overheads involved in implementing real-time optimistic concurrency control. Using a locking mechanism to e...
متن کاملOptimistic Secure Real-Time Concurrency Control Using Multiple Data Version
In many real time applications, security is an important requirement, since the system maintains sensitive information to be shared by multiple users with different security levels. A secure real-time database system must satisfy not only logical data consistency but also the timing constraints and security requirements associated with transactions. Even though an optimistic concurrency control...
متن کاملOn using similarity for concurrency control in real-time database systems
Most of the proposed concurrency control protocols for real-time database systems (RTDBS) are based on serializability theorem. Owing to the unique characteristics of real-time database applications and the importance of satisfying the timing constraint of the transactions, serializable concurrency control protocols are not suitable for RTDBS for most cases. In this paper, another notion of cor...
متن کاملConcurrency Control in Real-Time Databases by Dynamic Adjustment of Serialization Order
Time-critical scheduling in real-time database systems has two components: real-time transaction scheduling, which is related to task scheduling in realtime operating systems, and concurrency control, which can be considered as operation level scheduling. Most current research in this area only focuses on the transaction scheduling aspact while the concurrency control part remains untouched. In...
