![]() For example, it can store persistent Java Message Server (JMS) messages or temporarily store messages sent using the store-and-forward (SAF) feature.įor information about the Oracle WebLogic Server persistent store, see "Using the WebLogic Persistent Store" in Oracle Fusion Middleware Configuring Server Environments for Oracle WebLogic Server. The persistent store is a built-in, high-performance storage solution for Oracle WebLogic Server subsystems and services that require persistence. Network channels facilitate the effective use of network resources by segregating network traffic into channels based on the type of traffic.įor information about network channels, see "Configuring Network Resources" in Oracle Fusion Middleware Configuring Server Environments for Oracle WebLogic Server. Overload protection gives Oracle WebLogic Server the ability to detect, avoid, and recover from overload conditions.įor information about overload protection, see "Avoiding and Managing Overload" in Oracle Fusion Middleware Configuring Server Environments for Oracle WebLogic Server. Work Managers may be applied globally to a Oracle WebLogic Server domain or to a specific application or component.įor information about Work Managers, see "Using Work Managers to Optimize Scheduled Work" in Oracle Fusion Middleware Configuring Server Environments for Oracle WebLogic Server. This information is then used to optimize the performance of your application. Work Managers prioritize work based on rules you define and by monitoring actual run time performance statistics. 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.įor information about Oracle WebLogic Server clusters, see Oracle Fusion Middleware Using Clusters for Oracle WebLogic Server. Incoming requests can be routed to a Oracle WebLogic Server instance in the cluster based on the volume of work being processed. Oracle WebLogic Server clusters provide scalability and reliability for your applications by distributing the workload among multiple instances of Oracle WebLogic Server. Oracle WebLogic Server includes the following features to support high availability: Extensive security features protect access to services, keep enterprise data secure, and prevent malicious attacks. You can also configure Oracle WebLogic Server to monitor and tune application throughput automatically, without human intervention. New diagnostic tools allow system administrators to monitor and tune the performance of deployed applications and the Oracle WebLogic Server environment itself. These features allow enterprises to configure clusters of Oracle WebLogic Server instances to distribute load and provide extra capacity in case of hardware or other failures. In addition to the Java EE implementation, Oracle WebLogic Server enables enterprises to deploy business-critical applications in a robust, secure, highly available, manageable, and scalable environment. Oracle WebLogic Server also supports the Spring Framework, a programming model for Java applications which provides an alternative to aspects of the Java EE model. End-user clients access these applications using Web browser clients or Java clients. ![]() Oracle WebLogic Server is a complete implementation of the Sun Microsystems Java EE 5.0 specification, which 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. ![]() The Java EE Platform differs from the standard edition of Java in that it adds libraries which provide functionality to deploy fault-tolerant, distributed, multi-tier Java software, based largely on modular components running on an application server. ![]() Java EE is a widely used platform for server programming in the Java programming language. The Oracle WebLogic Server infrastructure supports the deployment of many types of distributed applications and is an ideal foundation for building applications based on SOA ( Figure 3-2). Oracle WebLogic Server is a scalable, enterprise-ready Java Platform, Enterprise Edition (Java EE) application server.
