In active real-time database systems, transaction concurrency control gets more difficult for integrating time constraint with active mechanism.

主动实时数据库因结合了时间限制与主动机制而使系统事务的并发控制变得更为复杂。

This paper proposes a hybrid optimistic real-time transaction concurrency control method based on high priority two phase locking scheme (HORTCC-SHP2PL).

提出了一种基于高优先级两段锁的混合乐观实时事务并发控制协议(HORTCC - SHP2PL)。

In addition to transaction locking, this approach is needed to control the concurrency of applications on a higher level.

除了事务锁定之外，这种方式可以在更高的级别上控制应用程序的并发性。
