Research of AC-Based OCC-FV： The Concurrency Control Protocol For Embedded Real-time Database System
摘要
Abstract
Alternative and compensation are two basic Characteristics of the real-time transaction, also are body of the concurrence control. At the same time, new problems are brought. AC-Based OCC-FV associates alternative and compensation with optimistic concurrency control OCC-FV. For each transaction in accepted queue, An alternative which cause no conflict can be chosen to join the ready queue as soon as possible. This is just a kind of ideal circumstance. If the conflict can not be avoided, a suitable alternative not only be chosen to join the concurrent control, although conflicts take place, the system always can also be kept in a safe state. And the optimistic concurrent control OCC-FV extending with compensation is adopted to resolve the conflicts, keeping system from catastrophe.关键词
