To reduce the resource competition among workflow instances, three method are given: heuristic rule based method, locking strategy and ant-generation blend algorithm based method. 针对工作流实例之间存在的资源竞争问题,给出了基于规则的调度、基于封锁的调度与蚂蚁-遗传混合算法的调度方案。
We also present an optimization scheme called Partition Coalition which is based on the server solution and which can substantially reduce the blocking time due to resource locking. 同时也设想了一种基于服务器方案的分区联合优化方案,它在实质上能够减少资源锁定一起的阻塞时间。
Because web transactions have distinct features, such as long-lived, autonomous and interactive, the traditional transaction mechanisms of resource locking and rollback are proved to be inappropriate. Web事务具备长时间运行、强自治性、交互性的特点,因此经典的事务处理技术如资源锁定、自动回滚等都不适用于Web事务。
Read the data with TCP/ IP protocol in real time and synchronise the resource with multithreading coding method to avoid the thread locking when the tracking is ceased. 3. 使用TCP/IP协议实现数据的实时读取,为了防止停止追踪时出现的线程锁死的现象,使用多线程编程方法同步资源。
