入口数据队列有一个数据队列头段结构,包括一个待处理分组区。
The ingress data queue has a data queue head structure, including a packets-to-be-processed field.
在这种情况下,可以认为信封相当于消息头,而地址相当于队列名。
In our circumstance the envelope can be considered equivalent to the message header, while the address is the queue name.
消息头保持纯文本格式,以便队列管理器能够正确路由它。
The message header remains in plain text so that the queue manager can route it properly.
在这种情况下,WebSpheremq添加死信头结构(MQDLH)到消息中,并将其放到死信(未传递消息)队列上。
In this case, WebSphere MQ adds a dead-letter header structure (MQDLH) to the message, and puts it on the dead-letter (undelivered-message) queue.
如果该头信息为true,那就通过一个名为SuccessfulOrderQueue的内存队列将该消息路由给第三个(也是最终的)服务,该服务会处理订单成功创建的消息。
If this header is true, we then route, via an in-memory queue named SuccessfulOrderQueue, the message to a third and final service dedicated to handle successful order creation messages.
在这种情况下,WebSphereMQ添加分布式头结构(MQDH)到消息中,并将其放在相关的传输队列中。
In this case, WebSphere MQ adds a distribution header structure (MQDH) to the message, and puts it on the relevant transmission queue.
传输头包括目标队列名称(RemoteQName)和队列管理器名称(RemoteQMgrName),即寻址信息。
The transmission header contains the name of the destination queue (RemoteQName) and queue manager (RemoteQMgrName), that is, the addressing information.
当消息位于远程队列时,WebSphereMQ 在将消息置于传输队列之前向其添加传输头结构(MQXQH)。
When a message is put on a remote queue, WebSphere MQ adds a transmission header structure (MQXQH) to the message before placing it on the transmission queue.
将一条数据移出队列的操作包括将头指针指向的条目取出,将一条数据移出队列的操作包括将头指针指向的条目取出,同时调整头指针使之指向排在被移出条目之后的位置。
Removing an entry from the queue involves extracting the entry pointed to by the head pointer and then adjusting the head pointer to point toward the entry that followed the removed entry.
Timestamp属性被使用了,一个消息队列的时间头将被设置为这个属性,而不是消息创建的时间。
Timestamp property is used, a queued message's Date: header is set to this property, not the message creation time.
