Middleware Management with Oracle Enterprise Manager Grid Control 10g R5

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.

You can monitor the entire Coherence cluster as a single target. The Coherence cluster homepage provides important aspects of the Coherence cluster. You can monitor availability and performance of the cluster from this page, as shown in the following screenshot:

The publisher and receiver success rate provides the health of the network and looks at how the nodes are communicating with each other. If the Publisher and Receiver Success Rates are significantly down, you have to worry about the health of the cluster because the nodes are not effectively communicating with each other.

It provides the number of nodes, objects, hosts, the CPU and memory usage and status of the services. For a caching service such as Distributed Cache, you should not see the status as ENDANGERED. Also, you will get an alert if any of the service status is ENDANGERED. It will appear in the Cluster homepage along with other metric alerts. You can use a notification mechanism such as...
