课程名称：Oracle Weblogic 12c 管理员完全指南 课程概述： 本课程专注于Oracle WebLogic Server，这是一个可扩展的企业级Java EE应用服务器。WebLogic Server的基础设施支持各种分布式应用程序的部署，是基于服务导向架构（SOA）构建应用程序的理想基础。SOA是一种设计方法，旨在最大化应用服务的重用。 WebLogic Server完整实施了Java EE 5.0规范，为创建可以访问多种服务（如数据库、消息服务和外部企业系统连接）的分布式Java应用程序提供了一整套标准API。最终用户通过Web浏览器客户端或Java客户端访问这些应用程序。它还支持Spring框架，这是一种Java应用程序的编程模型，为Java EE模型的某些方面提供了替代方案。 WebLogic Server集群通过将工作负载分配到多个WebLogic Server实例中，为应用程序提供可扩展性和可靠性。根据处理的工作量，传入请求可以路由到集群中的某个WebLogic Server实例。在硬件故障或其他故障的情况下，会话状态可供其他集群节点使用，以便恢复故障节点的工作。 工作管理器根据您定义的规则和实际运行时间性能统计信息优先处理工作。这些信息用于优化应用程序的性能。WebLogic Server持久性存储是一个内置的高性能存储解决方案，适用于需要持久性的WebLogic Server子系统和服务，例如，可以存储持久的JMS消息或通过存储转发功能临时存储消息。持久性存储支持持久化到基于文件的存储或JDBC支持的数据库。 企业级部署工具简化了应用程序从开发阶段到生产环境的部署和迁移。生产再部署功能使企业能够在不干扰旧版本的工作进展的情况下，部署新版本的应用程序。
Oracle WebLogic Server is a scalable, enterprise-ready Java Platform, Enterprise Edition (Java EE) application server.The WebLogic Server infrastructure supports the deployment of many types of distributed applications and is an ideal foundation for building applications based on Service-Oriented Architectures (SOA).SOA is a design methodology aimed at maximizing the reuse of application servicesThe WebLogic Server complete implementation of the Java EE 5.0 specification provides a standard set of APIs for creating distributed Java applications that can access a wide variety of services, such as databases, messaging services, and connections to external enterprise systems.End-user clients access these applications using Web browser clients or Java clients. It also supports the Spring Framework, a programming model for Java applications which provides an alternative to aspects of the Java EE modelWebLogic Server clusters provide scalability and reliability for your applications by distributing the workload among multiple instances of WebLogic Server. Incoming requests can be routed to a WebLogic Server instance in the cluster based on the volume of work being processed. In case of hardware or other failures, the session state is available to other cluster nodes that can resume the work of the failed node.Work Managers prioritize work based on rules you define and by monitoring actual run time performance statistics. This information is then used to optimize the performance of your application.WebLogic Server persistent store is a built-in, high-performance storage solution for WebLogic Server subsystems and services that require persistence. For example, it can store persistent JMS messages or temporarily store messages sent using the Store-and-Forward feature. The persistent store supports persistence to a file-based store or to a JDBC-enabled database.Enterprise-ready deployment tools facilitate deployment and migration of applications from the development phase to a production environment.Production redeployment enables enterprises to deploy a new version of their application without interrupting work in progress on the older version.
