Research on Database Synchronization Technology Based on Message Queue and XML 基于消息队列和XML的数据同步技术研究
When the initialization of controlling program is finished, the synchronization operates I / O request information queue and begins with parallel scheduling according to current situation. 控制程序初始化完成后,进入同步控制阶段,同步控制阶段操作I/O请求信息队列,并根据当前条件启动并行调度阶段的不同步骤。
Let's first demonstrate the successful managed synchronization of messages from a source to a target Queue Manager. 让我们首先演示源QueueManager和目标QueueManager之间的成功的受控制的消息同步。
Synchronization recovery is an important technique combined with the queue mechanism in Lite / 2 to optimize the communication costs. 此外,Lite/2将同步失败恢复和队列技术相结合来优化事务性同步过程的总通信代价。
Two types of communication nodes are designed, one is bus-Ethernet network interface card which has clock synchronization and protocol conversion functions, and the other is train gateway node which provides simple routing and queue scheduling functions. 最后,本文使用ARM系列微处理器和嵌入式操作系统设计了两类列车以太网通信节点:一类是具有时钟同步及协议转换功能的总线-以太网网卡,另一类是具有路由和队列调度功能的车辆网关。
