A Survey of Concurrency Control Algorithms in the Operating Systems
Concurrency control is one of the important problems in operation systems. Various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. This paper presents a survey of the current methods for controlling...

متن کاملThe Performance of Concurrency Control Algorithms for Database Management Systems
This paper describes a study of the performance of centralized concurrency control algorithms. An algorithm-independent simulation framework was developed in order to support comparative studies of various concurrency control algorithms. We describe this framework in detail and present performance results which were obtained for what we believe to be a representative cross-section of the many p...
متن کاملPerformance of Concurrency Control Algorithms for Real-Time Database Systems
In this paper, we investigate the key components of a reasonable model of real-time database systems (RTDBSs), including the policy for dealing with tardy transactions, the availability of resources in the system, and the use of pre-knowledge about transaction processing requirement. We employ a fairly complete model of an RTDBS for studying the relative performance of locking and optimistic co...
متن کاملNew Concurrency Control Algorithms for Accessing and Compacting B-Trees
This paper initially presents a brief but fairly exhaustive survey of solutions to the concurrency control problem for B-trees. We then propose a new solution, which is characterized by the use of variable-length indices, the employment of a single lock type for the usual access operations and preemptive splits as well as delayed catenations and subdivisions. We also introduce a new compaction ...
