tuxedo协议脚本编写技术指南

第第PAGE10TUXEDOTUXEDO协 编写技术指前文档目本文档描述了TUXEDO协议的基础知识和编写方法，旨在让阅读者能在短时间内快速掌握简单的TUXEDO协议的编写方法。为以后同类型协议脚的开发提供参考适用范围与对本文档不对Loadrunner基础开发方法和TUXEDO中间件基础知识做过多描述，初学者需要掌握基本的C语言知识。对于涉及本文中一些更次的技术性问题，请参术语及参ATMI,Application-to-TransactionMonitorInterface即“应用事务监视接口”，是TUXEDO系统的编程接口。他实现了X/Open组织定义的分布式事务处理（DTP）模型，为应用程序提供命名、通信、队列、事务和缓冲区管理等基础服务。消息队是一些空间，或者是内存（IPC消息队列或在硬盘上。TUXEDO协议介TUXEDO简XEDO中都可以使用XEDO作为一款型中间件其主要功能用于管理分布于不同计算机上的数据的一致性保障系统处理能力的效率以及均衡负载等目前的银行邮政XEDO连接协议。TUXEDOTUXEDO协 编写技术指TUXEDO协议通讯方式介①向System/T发出查询请求，以找到Server消息队列的地址②根据找到的地址将请求发送到Server的消息队列中 Server处理请求，并将结果返回给的消息队列/△订阅与发布TUXEDO协议Buffer类型介
