摘要
为实现语义可串行性调度而提出的基于两段锁协议的并发控制算法无法保证所得到的历史具有可恢复 性,为解决该算法的可用性问题,利用并发控制和恢复的统一模型给出一种基于两段锁协议的并发控制算法。
The history, which is produced by the concurrency control algorithm based on two phase locking protocol to implement a sematic serializibility schedule, cannot be ensured to be recoverable. To solve the usability problem, with the unifying model of concurrency control and recovery, a concurrency control algorithm based on two phase locking protocol is given.
