服務整合
此頁面提供尋找服務整合相關資訊的起始點。
服務整合提供非同步傳訊服務。在非同步傳訊中,生產端應用程式不會將訊息直接傳送至消費端應用程式。它們反而會將訊息傳送至目的地。消費端應用程式會從這些目的地接收訊息。生產端應用程式可以傳送訊息,而且不需等到消費端應用程式收到訊息,即可繼續處理。必要的話,目的地會儲存訊息,直到消費端應用程式已準備好接收它們為止。

Service integration technologies
Service integration is a set of technologies that provides asynchronous messaging services. Use this topic to learn about the technologies on which WebSphere® Application Server service integration applications are developed and implemented.Service integration buses
A service integration bus is a group of one or more application servers or server clusters in a WebSphere Application Server cell that cooperate to provide asynchronous messaging services. 匯流排中的應用程式伺服器或伺服器叢集,稱為匯流排成員。 In the simplest case, a service integration bus consists of a single bus member, which is one application server.Bus members
The members of a service integration bus can be application servers, server clusters, or IBM MQ servers. Bus members that are application servers or server clusters contain messaging engines, which are the application server components that provide asynchronous messaging services. Bus members that are IBM MQ servers provide a direct client connection between a service integration bus and queues on a IBM MQ queue manager.Support for JMS 2.0 features in WebSphere Application Server version 9.0
JMS 2.0 introduces many new functions that enhance ease of use, simplicity, and asynchronous support of JMS applications. JMS 2.0 is part of the Java EE 7 platform and can be used in Java EE web or EJB applications (along with J2SE environment).Messaging engines
每個服務整合伺服器或叢集匯流排成員,都包含一個稱為傳訊引擎的元件,用來處理傳訊功能的傳送和接收要求,以及管理目的地。Bus destinations
Service integration has the following types of bus destinations each with a different purpose: queue, topic space, foreign, and alias.Message stores
Message stores are important in the operation of messaging engines. To host queue-type destinations, a messaging engine includes a message store where, if necessary, it can hold messages until consuming applications are ready to receive them, or preserve messages in case the messaging engine fails. Each messaging engine has one and only one message store. This can either be a file store or a data store.Service integration security
Messaging security ensures that service integration bus users are authenticated, resources are protected by security checks, and messages are secured when they are in transit. Use these topics to learn how to secure the service integration bus and protect messages that are sent and received.High availability and workload sharing
Use these topics to learn about high availability and workload sharing.Mediations
A mediation is a Java™ program that extends the messaging capabilities of WebSphere Application Server. Mediations can be used to simplify connecting systems, services, applications, or components that use messaging.Service integration configurations
A service integration configuration can range from a single host running two connected applications to a globally-dispersed set of hundreds or thousands of communicating applications running over the bus.Service integration notification events
You can monitor your service integration environment by using notification events.Message reliability levels - JMS delivery mode and service integration quality of service
Messages have a quality of service attribute that you can use to specify how reliable message delivery will be. JMS applications send messages with a JMS delivery mode (persistent or nonpersistent), then service integration uses JMS connection factory settings to map the JMS delivery mode to a service integration message reliability setting. Additional settings on bus destinations (including foreign destinations and alias destinations) can override this message reliability.Dynamic reloading of configuration files
Updates to configuration information are dynamically passed to the server if you use dynamic reloading of configuration files. These updates are available to a messaging engine even if it is not started.Service integration backup
You should back up your service integration setup on a regular basis so that it can be restored in the event of an unrecoverable failure.
