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.

How plug-ins work


We learnt in Chapter 1,Enterprise Manager Grid Control, about targets, target metadata, and target collection file. Target is an entity managed by the Enterprise Manager Grid Control. For each target type there is a target metadata file that defines the properties for the target, the metrics that need to be collected for a target and the mechanism to collect those metrics. For each target type there is a collection file that defines at what frequency metrics should be collected and at what frequency metrics should be persisted. You may want to revisit Chapter 3, Enterprise Manager Key Concepts and Subsystems, before we continue with this chapter. Once you have familiarized yourself about the purpose of these entities, let's use them to see how plug-ins work.

Plug-in artefacts

There are two types of artefacts for a plug-in:

  1. 1. Mandatory artefacts: Target metadata and Target collection are the mandatory artefacts; with these artefacts all of the monitoring metrics can be collected...
