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.

Service Level Management


We saw in earlier sections that using target subsystem and monitoring subsystem we can monitor any resource in a datacenter. We can see the availability of any IT resource by looking at the history of status metrics. In the traditional approach, the history of status metric is good enough to measure system performance.

In most of the datacenters today, IT systems performance is measured by Service Level Agreements (SLA). SLA includes the performance indicators to be used, thresholds for the performance indicators, and expected availability of the IT resource in terms of the performance indicators. For example, one sample SLA for a Linux host includes CPU usage and IO rate as performance indicator; it also includes acceptable thresholds for CPU and IO rate. This SLA measures the availability of Linux servers in terms of CPU usage and IO rate.

Enterprise Manager provides support for defining and monitoring service level agreements. It provides necessary backend...
