IBM WebSphere MQ的C#工具类以及源码（net）_.NET_编程开发_程序员俱乐部

简单的介绍一下MQ常用的对象

Queue Manager

队列管理器

主要负责管理队列、通道等，类似与Oracle中的Oracle实例的概念，在一台服务器中可以定义多个Queue Manager。

Queue

队列

是存放Message的对象，是我们主要操作的对象。类似与Oracle中的表的概念。

Message

消息

实际放入Queue中的消息，该消息可以存储字符串、Stream等对象。

Channel

通道

是我们的应用以及两个Queue Manager操作的链接对象

Process

过程

Queue的分类：

Local Queue

本地队列

主要存储消息的对象

Remote Queue

远程队列

和另外一个Queue Manager通讯的队列

Mode Queue

模板队列

建立一个队列模板，通过这个模板可以建立与模板相同属性的动态队列。

Dynamic Queue

动态对了（临时队列）

可以在程序中创建和删除的临时队列
