1 Introduction and Roadmap

This document describes how to use the Java Management Extensions (JMX) to how to reduce the cost of operating and maintaining your applications by building management facilities into your applications. The simplest facility is message logging, which reports events within your applications as they occur and writes messages to a file or other repository. Depending on the criticality of your application, the complexity of the production environment, and the types of monitoring systems your organization uses in its operations center, your needs might be better served by building richer management facilities based on Java Management Extensions (JMX). JMX enables a generic management system to monitor your application; raise notifications when the application needs attention; and change the configuration or run-time state of your application to remedy problems.

The following sections describe the contents and organization of this guide—Developing Manageable Applications Using JMX for Oracle WebLogic Server.

Document Scope and Audience

This document is a resource for software developers who develop management services for Java EE applications. It also contains information that is useful for business analysts and system architects who are evaluating WebLogic Server or considering the use of JMX for a particular application.

It is assumed that the reader is familiar with Java EE and general application management concepts.

The information in this document is relevant during the design and development phases of a software project. This document does not address production phase administration, monitoring, or performance tuning topics. For links to WebLogic Server documentation and resources related to these topics, see Related Documentation.

This document emphasizes a hands-on approach to developing a limited but useful set of JMX management services. For information on applying JMX to a broader set of management problems, refer to the JMX specification or other documents listed in Related Documentation.
