这与客户端应用程序形成鲜明对比，其中连接的一端是消息通道代理，另一端是应用程序代码。
Contrast this with a client application where one side of the connection is a message channel agent and the other is application code.
消息可由队列管理器、消息通道、消息通道代理程序(mca)和应用程序放到死信队列上。
Messages can be put on the dead-letter queue by queue managers, message channel agents (MCAs), and applications.
用于将队列管理器连接到另一个队列管理器的通道称为MCA 通道，因为它们使用消息通道代理。
The channels that connect queue managers to one another are known as MCA channels because they use a message channel agent.
这些更改由队列管理器、消息通道代理程序或其他WebSphereMQ基础设施自动完成，且对应用程序透明。
The changes are made automatically by queue managers, message channel agents, or other WebSphere MQ infrastructures, and are transparent to applications.
其原因在于通道代理会保留消息描述符的内容，它会设置所有字段以匹配来自发送队列管理器的消息。
The reason for this is that the channel agent will preserve the contents of the message descriptor by setting all the fields to match the message from the sending queue manager.
异步消息传递系统通常依赖于消息总线或消息代理公开用于接收消息生成方所发布的消息的队列或事件通道。
An asynchronous messaging system typically relies on a message bus or broker to expose queues or event channels that receive messages published by message producers.
