Základní info
In this course, you learn the job of an administrator of Java Message Service (JMS), which enables loosely coupled, reliable, asynchronous communication among Java applications. You explore WebLogic Server, which includes an enterprise-grade JMS implementation based on an administrative framework that is both powerful and flexible.Learn how to:Configure JMS servers and destinationsConfigure JMS high availabilityMigrate messages from a failed serverMonitor and tune JMS performanceTroubleshoot JMS problemsBenefits to YouThis course teaches you how to increase the performance and scalability of your organization’s applications and services using Oracle WebLogic Server -- the world's #1 application server. You learn how to simplify deployment and significantly improve time-to-market. When you complete this course, you'll have the skills to configure, manage, and monitor WebLogic Server JMS resources according to proven best practices.High Availability and MigrationExpert Oracle University instructors teach you how to configure your Oracle WebLogic Server environment to provide load balancing and failover for JMS resources. You'll be able to identify when to use configured and dynamic clusters for JMS. In addition, you'll learn how to move JMS resources across servers in your cluster in response to a server failure or during scheduled server maintenance.Tuning and TroubleshootingUse a variety of tools to investigate, identify, and fix common JMS problems.
