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.

Monitoring


Enterprise Manager performs round-the-clock monitoring of targets by collecting the performance data. Unmanned monitoring is one of the key features of Enterprise Manager Grid Control. Monitoring subsystem is a crucial piece in unmanned monitoring of targets. Let's learn about monitoring subsystem.

We will now see the major building blocks of the monitoring subsystem in greater detail.

Fetchlets

A managed resource can expose performance indicators through various interfaces like JMX, SNMP, and so on. For example, WebLogic Server performance indicators are exposed through a JMX interface. Enterprise Manager provides executables that can access performance data from most of the standard interfaces. These executables are called fetchlets. There is one fetchlet for each data access mechanism. Some useful fetchlets are SNMP, JMX, and URLXML fetchlets, which can be used to access data from SNMP interface; JMX interface, and URL interfaces respectively.
