Introduction and Roadmap
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 and 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 BEA's proprietary classes, BEA recommends that remote JMX clients use WebLogic Server protocols (such as T3) to connect to WebLogic Server instances.
This document describes creating JMX clients that monitor and modify WebLogic Server resources.

Document Scope and Audience
This document is a resource for software vendors who develop JMX-compatible management systems. 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 J2EE and general application management concepts. 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.
Guide to this Document
- This chapter, Introduction and Roadmap, introduces the organization of this guide.
