第 1部分介绍集群的知识、集群节点的职责，以及应用服务器集群中节点的管理。
This installment, the first part of the series, introduces you to clustering, the responsibility of the cluster nodes, and managing the nodes in an application server cluster.
将应用服务器或应用服务器集群作为总线成员添加时，将自动在所涉及的总线成员上定义一系列资源。
Adding an application server, or cluster of application servers, as a member of a bus automatically defines a number of resources on the bus member in question.
垂直集群：在同一主机上运行应用服务器的多个节点或实例。
Vertical clustering: Running multiple nodes or instances of an application server on the same host.
通过这种方式，负载均衡的集群的效率就可以得到保持，所有应用服务器都能够连接到任意数据库以完成它们所支持的用户会话。
In this way the load balanced cluster efficiency can be maintained with all application servers being able to connect to any database for the user sessions they are supporting.
水平集群：在不同的主机上运行应用服务器的多个节点或实例。
Horizontal clustering: Running multiple nodes or instances of an application server on different hosts.
对集群的管理，以及对某个或者某些节点上应用服务器工作负载均衡的管理，都通过部署管理器来完成。
The management of clusters and the management of workload balancing of the application servers across one or several nodes are accomplished via the deployment manager.
现在，部署管理员已经知道可用的节点，于是可以创建应用服务器并将其添加到集群中。
Now that the deployment manager is aware of the available nodes, application servers can be created and added to the cluster.
注册了所有节点之后，该脚本继续为每个节点创建一个应用服务器，并将其添加到集群。
Once all the nodes have been registered, the script will continue to create an application server for each node and add it to the cluster.
客户机请求跨越集群进行路由，因此将在所有应用服务器进程之间分配工作负载。
The client requests are routed across the cluster, thereby distributing the work load among all the application server processes that are members.
把应用服务器进行集群化的主要原因是提升它的性能和可用性。
The main reasons for clustering an application server are to increase its performance and stability.
与应用服务器中的集群有关的另一个领域是缓存。
Another area related to clustering in an application server is caching.
以下场景帮助更进一步描述如何在集群应用服务器环境中配置并使用客户端优化。
The following scenario is intended to help further describe how to configure and work with client optimization in clustered application server environments.
在展开作用域选择下拉列表后，列表中会展示所有可用的节点、集群、以及应用服务器实例。
After you choose to show the scope selection drop-down list, the list shows all the available nodes, clusters, and the application server instances.
应用服务器(或集群)是总线的成员。
为了使这些目的地实际可用，可指定一个消息传递基础结构可以运行的应用服务器进程(或进程集群)。
To make those destinations physically available, you can designate an application server process (or cluster of processes) where the messaging infrastructure can run.
另外，也可以用在对吞吐量非常重要的J2EE集群应用服务器的环境中。
In addition, it can also be used in environments where extreme throughput is crucial by deploying it on a J2EE clustered application server.
大多数路由器组件在向集群成员(应用服务器)转发请求时都可以维护相应的亲缘性。
Most router components can maintain the appropriate affinities while forwarding requests to the cluster members (application servers).
然而，本例用于支持集群环境而不是单个应用服务器节点。
However, in this case it is extended to support a cluster environment instead of an environment with a single application server node.
在集群成员上完成了所有的更改后，使用WebSphere管理控制台停止后再启动应用服务器。
Once all changes have been made on the cluster members, stop and start the application servers using the WebSphere administration console.
对于每个应用服务器(非集群)，请转到消息传递引擎入站传输面板并禁用InboundBasicMessaging传输。
For each application server (not cluster), go to the messaging engine inbound transport panel and disable the InboundBasicMessaging transport.
OpenESB是JBI的一个开源实现，当其运行在GlassFish应用服务器上时，它包含了一个使用了集群jbi实例的同构拓扑选项。
OpenESB, an open source implementation of JBI, includes a homogeneous topology option using clustered JBI instances when run in a GlassFish Application Server.
Shoal是GlassFish (v 2及后续版本)和JonAS应用服务器的集群引擎。
Shoal is the clustering engine for GlassFish (v2 and later versions) and JonAS application servers.
WebSphereApplicationServer集群机制允许将整个应用服务器(包括ejb容器、EJB、web容器、Web模块和Servlet)作为一个集群进行复制。
The WebSphere application server clustering mechanism allows a complete application server (including EJB container, EJBs, Web containers, Web modules, and servlets) to be copied as a cluster.
两台应用服务器(加入集群)。
