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 |
