1 Introduction and Roadmap

This document describes creating JMX clients that monitor and modify WebLogic Server resources. To integrate third-party management systems with the WebLogic Server management system, WebLogic Server provides standards-based interfaces that are fully compliant with the Java Management Extensions (JMX) specification. Software vendors can use these interfaces to monitor WebLogic Server MBeans, to change the configuration of a WebLogic Server domain, and to monitor the distribution (activation) of those changes to all server instances in the domain. While JMX clients can perform all WebLogic Server management functions without using Oracle's proprietary classes, Oracle recommends that remote JMX clients use WebLogic Server protocols (such as T3) to connect to WebLogic Server instances.

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