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 WebLogic Server


You can monitor both the availability and performance of WebLogic Server Domains from Enterprise Manager. You can view both real time and historical metrics of your WebLogic Server Domains. As we discussed earlier, WebLogic Server has three distinct entities such as WebLogic Server Domain, cluster and managed server. Each of these are modeled as separate targets in Enterprise Manager. Thus each domain, managed server and cluster has separate homepages, status, and so on.

Availability and state

You can monitor the status of WebLogic Server. WebLogic Server has several states such as RUNNING, ADMIN, SHUTDOWN, STARTING, and so on. However, an Enterprise Manager target can have only two statuses either UP or DOWN. In a production monitoring purpose it makes sense because your applications are unavailable when the WebLogic Server is in a state other than RUNNING. Enterprise Manager shows the status as UP only when the state of the WebLogic Server is RUNNING and...
