Overview of this book

Today's IT environment is very complex, encompassing a myriad of technologies and middleware platforms. Many organizations have large and heterogeneous middleware platforms that power their enterprise applications and it is often a real challenge for administrators to meet agreed service levels and minimize downtime. Oracle Enterprise Manager allows administrators to manage the complete lifecycle of an entire application infrastructure for middleware and SOA applications. This book will help you kick-start the setup of Oracle Enterprise Manager Grid Control and master all aspects of middleware management supported by Oracle Enterprise Manager. This book, written by senior members of the Oracle team serves as the only hands on guide to provisioning middleware and implementing proactive monitoring to maximize application performance and compliance using Oracle Enterprise Manager. The book starts with an introduction to the challenges faced by middleware administrators in their everyday life, and how Oracle Enterprise Manager helps solve those challenges. This book will help you manage your middleware infrastructure and applications effectively and efficiently using Oracle Enterprise Manager. By following the practical examples in this book you will learn to proactively monitor your production middleware applications running on Oracle Application Server, Oracle WebLogic Server, Oracle SOA suite (such as Oracle BPEL Process manager), Oracle Server Bus, and Oracle Coherence. You will also learn different aspects to proactive monitoring and alert notifications, service level and incident management, diagnostics for production applications, lifecycle automation using out-of-the-box deployment procedures, and patching mechanisms. This book also helps you to master best practices for managing your middleware and SOA applications for optimal service performance and reduced down time.

Chapter 10. Managing Coherence Cluster

Oracle Coherence is an in-memory caching solution that enables organizations to predictably scale mission-critical applications. Oracle Coherence comes with several editions or flavors. You can either use Coherence as a caching solution within your enterprise applications as a shared library, or as an external data grid solution providing distributed data management capabilities. The Coherence product does not come with a management console providing a visibility gap to the Coherence cluster. Effectively, managing your Oracle Coherence environment is critical to maximizing application availability and ensuring a high Quality of Service (QoS). In this chapter, we will learn:

  • What an Oracle Coherence cluster is

  • How to discover a Coherence cluster

  • Monitoring and management of a Coherence cluster

  • Provisioning of a Coherence cluster and nodes
