当一个EJB组件想访问数据库、消息队列服务器或者其它一些事务性资源时,它需要到资源管理器的连接(通常是使用JNDI)。
When an EJB component wants to access a database, a message queue server, or some other transactional resource, it acquires a connection to the resource manager (usually by using JNDI).
而且,J2EE规范只认可三种类型的事务性资源 ―JDBC数据库、JMS消息队列服务器和“其它通过JCA访问的事务性服务”。
Moreover, the J2EE specification only recognizes three types of transactional resources -- JDBC databases, JMS message queue servers, and "other transactional services accessed through JCA."
资源管理器存储应用程序状态,常常是数据库,但也可能是消息队列服务器(在J2EE 应用程序中,它们将是 JMS提供者)或其他事务性资源。
The RMs store the application state and are most often databases, but could also be message queue servers (in a J2EE application, these would be JMS providers) or other transactional resources.
在我们这个项目中,邮局就是消息服务器,邮政人员是队列管理器。
In our project, the post office is the message server and the postmaster is the queue manager.
在本文中,我分析了J2EE环境中服务器端资源(例如数据库、消息队列、目录和企业系统)的连接合用。
In this article, I examine connection pooling in a J2EE environment for server-side resources such as databases, message queues, directories, and enterprise systems.
使用MQ服务器的应用程序可以发送去往设备队列管理器的消息。
Applications using the MQ server can send messages that are destined for device queue managers.
运行时服务器将与操作关联的相关数据作为操作有效负载从中间对象传递到出站JMS消息队列。
The run time server passes the relevant data associated with the action from the intermediate object as an action payload to the outbound JMS message queue.
运行时服务器从JMS队列检索消息,并使用事件有效负载中包含的值填充适当的中间对象。
The run time server retrieves the message from the JMS queue and populates the appropriate intermediate objects with the values contained in the event payload.
服务器向笔记本中的本地队列管理器发送回复消息。
The server sends a reply message to the local queue manager on the laptop.
使用通道压缩有助于提高在应用服务器和队列管理器之间传输消息的速度。
The use of channel compression can help increase the speed at which messages are transferred between an application server and a queue manager.
应用程序包含消息驱动的企业bean (MDB),后者与相同应用服务器中定义的jms队列相连。
The application will contain a message-driven enterprise bean (MDB) connected to a JMS queue defined within the same application server.
jrules-bres-mdb-WAS6.jar必须被部署到应用程序服务器,这样在消息到达请求队列时,就可以调用它包括的 JRules MDB。
The jrules-bres-mdb-WAS6.jar must be deployed to the application server so that the included JRules MDB can be called when a message arrives on the request queue.
消息存储在队列里,MQ服务器允许您将消息加入到队列以及从队列中取走消息。
Messages are stored in queues, and MQ servers allow you to enqueue messages onto queues, and dequeue messages from them.
网关队列管理器方便了设备队列管理器和MQ服务器之间的消息交换。
A gateway queue manager facilitates the exchange of messages between device queue managers and MQ servers.
尽管一次查询请求可能不会返回队列中的所有消息,但是如果一直从队列中获取消息,最终会取样所有服务器,您就会得到所有消息。
Even though a particular request may not return all messages in the queue, if you keep retrieving from the queue it will end up sampling all of the servers and you'll get all your messages.
对于从MQ服务器到设备队列管理器的消息,网关提供存储转发设备来为当前未联机的设备保存消息。
For messages going from MQ servers to device queue managers, the gateway provides a store-and-forward facility holding messages for devices that are not currently online.
同样,要发送给客户机应用程序的消息被保存在服务器端消息队列中,当设备恢复在线状态时,将这些消息发送给客户机应用程序。
Similarly, messages destined for client applications are held in server-side message queues and then sent to the client applications when the device is back online.
单独节点上的队列管理器:最后一个选项是在不同物理服务器上的队列管理器之间划分流量,其中每个队列管理器为不同类型的消息做了优化。
Queue managers on separate nodes: the ultimate option is to split the traffic between queue managers on different physical servers, where each is tuned for a different type of message.
在消息传递中间件中,通过使用一个名为消息代理(或队列管理程序)的服务器组件以消息的形式在系统间传递数据来实现连接。
In messaging middleware, connectivity is achieved by passing data between systems through a server component known as a message broker (or a queue manager) in the form of messages.
而另一个JMS客户机(订阅者)则可以访问这个队列,并从该服务器获取这条消息。
Another JMS client (subscriber) can access the queue and retrieve the message from the server.
对于从设备队列管理器到MQ服务器的消息,网关提供了一个穿透设备,它将消息从compact mqe格式转换成mq格式。
For messages going from device queue managers to MQ servers, the gateway provides a passthrough facility, transforming messages from the compact MQe format to the MQ format.
将在OpenJMS服务器中为应用程序公开的每个Web服务打开单个队列,并为此队列创建一个消息侦听器(此操作将在应用程序启动时进行一次)。
It opens a single queue for each web service exposed by the application and creates a message listener for this queue (this is done once at the time of startup of application) all in OpenJMS server.
在代码执行时,消息会传递给WebSphereMQ服务器的队列。
The message will be delivered to the WebSphere MQ server's queue on the execution of the code.
公钥证书用于消息的身份验证,也就是向“消息队列”服务器验证消息的发送方(客户端)。
Public key certificates are used for message authentication, which verifies the sender of a message (the client) to a message Queuing server.
本地客户端与服务器的通讯是通过直接的函数调用和消息队列,因为他们在同一个进程中。
The LocalClient communicates with the (local) server through direct function calls and message queues, since it is in the same process.
消息队列服务的服务器,版本2.0。
