Getting Started with the Java Dynamic Management Kit 4.0

Preface

The Java Dynamic Management^TM Kit provides a set of Java classes and tools for developing management solutions. This product conforms to the specification of the Java Management extensions (JMX) which define a three-level architecture: resource instrumentation, dynamic agents and remote management applications. Such an architecture is applicable to network management, remote system maintenance, application maintenance and service provisioning.

The Getting Started with the Java Dynamic Management Kit 4.0 Guide presents the architecture of the Java Dynamic Management Kit, introducing the key concepts of the product and the development process.

Who Should Use This Book

This book is aimed at anyone seeking an introduction to the concepts and components of the Java Dynamic Management Kit.

Familiarity with Java programming and the JavaBeans^TM component model is assumed.

This book is not intended to be an exhaustive reference: management tutorials intended to demonstrate each of the management levels and how they interact are covered in Java Dynamic Management Kit 4.0 Tutorials, and the complete Javadoc API definitions are provided in the product documentation package.

Before You Read This Book

In order to build and run the sample programs in these tutorials, or use the tool commands, you must have a complete installation of the Java Dynamic Management on your machine. Please refer to the Java Dynamic Management Kit 4.0 Installation Guide and Release Notes document for instructions on how to install the product components and configure your environment.

After familiarizing yourself with the concepts of the Java Dynamic Management Kit, you should familiarize yourself with the tools provided with the Java Dynamic Management Kit and learn how to instrument new or existing resources for management. The following books are part of the product documentation set:

Java Dynamic Management Kit 4.0 Tools Reference
Java Dynamic Management Kit 4.0 Tutorials

These books are available on-line after you have installed the documentation package of the Java Dynamic Management. The on-line documentation also includes the Javadoc API for the Java packages and classes, including those of the Java Management extensions. Using any web browser, open the home-page corresponding to your platform:

Operating Environment	Home-Page Location
Solaris	`installDir/SUNWjdmk/jdmk4.0/JDKversion/index.html`
Windows NT	`installDir\SUNWjdmk\jdmk4.0\JDKversion\index.html`

In these file names, installDir refers to the base directory of your Java Dynamic Management installation. The JDKversion is that of the Java Development Kit which you use and which you selected during installation; it can be either 1.1 or 1.2. This convention is used throughout this book whenever referring to files or directories which are part of the installation. In a default installation procedure, installDir is:

/opt on the Solaris platform
C:\Program Files on the Windows NT platform
