摘　　要：铁路客票系统使用数据库传输中间件DBCS和连接交易管理中间件CTMS,实现生产数据的分时传输、售退票请求等异地数据库之间的数据存取。DBCS实现车站、地区中心、铁道部三级系统之间存根、席位、运能、营销统计等生产数据的传输,保证各级数据的准确性、完整性。CTMS主要用于售票事务管理和用户连接转发、负载均衡和流量控制、安全管理、用户名和口令校验、并对客户端发出的命令进行过滤,拒绝执行其中的某些命令。在中间件基础上研制出的消息中间件产品JWMQ可以提供网络节点间的可靠传输,支持远程监控和配置,支持文件传输和断点续传。JWMQ系统实现可视化网络通断和核心进程生存情况监控,支持对称密钥加密传输,支持传输的多种优先级管理策略和高效稳定的流控制。By means of Database Communication Middleware System (DBCS) and Connection & Transaction Management Middleware System (CTMS), the Chinese Railway Ticketing System realizes its time-sharing transmission of the productive data and some data access operations such as ticket sale/refund request in (distributed) database system. DBCS achieves the transfer of productive data such as counterfoil,seat (information),transportation capacity & marketing statistics, ensuring the correctness and integrity among (station),center bureau and ministry of railway. CTMS is used to accomplish the management of ticket sale transaction & user request forwarding; load balance and flow control; security management; validation of user name & password,filtration of requests from client and refuse to execute some of them. In addition,based on the above two middleware systems, we developed our MOM product-JWMQ, which could provide reliable data transmission between different network nodes, fulfill remote monitoring & configuration as well as transfer or re-transfer a file from the break point. JWMQ can also visualize the network status and the life-circle of kernel process for surveillance, upholding multi-priority management strategy and supporting an efficient & stable stream control.
