This book, the Message Queue Technical Overview, provides an introduction to the technology, concepts, architecture, capabilities, and features of the Message Queue messaging service.
As such, this book provides the foundation for other books within the Message Queue documentation set, and should be read first.
This preface consists of the following sections:
This guide is meant for application developers, administrators, and other parties who plan to use the Message Queue product or who wish to understand the technology, concepts, architecture, capabilities, and features of the product. In the context of Message Queue:
An application developer is responsible for writing Message Queue client applications that use the Message Queue service to exchange messages with other client applications.
An administrator is responsible for setting up and managing a Message Queue messaging service.
This book does not assume any knowledge of messaging systems or the Java Message Service (JMS) specification, which is implemented by the Message Queue service.
There are no prerequisites to this book. You should read this book to gain an understanding of basic Message Queue concepts and technology before reading the Message Queue developer and administration guides.
This guide is designed to be read from beginning to end; each chapter builds on information contained in earlier chapters. The following table briefly describes the contents of each chapter.
Table P-1 Book Contents
This section describes the following conventions used in Message Queue documentation:
The following table describes the typographic conventions that are used in this book.
Table P-2 Typographic Conventions
The following table explains symbols that might be used in this book.
Table P-3 Symbol Conventions
The following table shows the conventions used in Message Queue documentation for the default UNIX system prompt and superuser prompt for the C shell, Bourne shell, Korn shell, and for the Windows operating system.
Table P-4 Shell Prompt Conventions
Message Queue documentation makes use of three directory variables; two of which represent environment variables needed by Message Queue. (How you set the environment variables varies from platform to platform.)
The following table describes the directory variables that might be found in this book and how they are used. Some of these variables refer to the directory mqInstallHome, which is the directory where Message Queue is installed to when using the installer or unzipped to when using a zip-based distribution.
Note - In this book, directory variables are shown without platform-specific environment variable notation or syntax (such as $IMQ_HOME on UNIX). Non-platform-specific path names use UNIX directory separator (/) notation.
Table P-5 Directory Variable Conventions

Table P-6 Message Queue Documentation Set
The Message Queue message service conforms to the Java Message Service (JMS) application programming interface, described in the Java Message Service Specification. This document can be found at the URL
JMS and Message Queue API documentation in JavaDoc format is included in Message Queue installations at IMQ_HOME/javadoc/index.html. This documentation can be viewed in any HTML browser. It includes standard JMS API documentation as well as Message Queue–specific APIs.
Message Queue provides a number of example client applications to assist developers.
Example Java client applications are included in Message Queue installations at IMQ_HOME/examples. See the README files located in this directory and its subdirectories for descriptive information about the example applications.
Example C client applications are included in Message Queue installations at IMQ_HOME/examples/C. See the README files located in this directory and its subdirectories for descriptive information about the example applications.
Example Java Management Extensions (JMX) client applications are included in Message Queue installations at IMQ_HOME/examples/jmx. See the README files located in this directory and its subdirectories for descriptive information about the example applications.
Online help is available for the Message Queue command line utilities; for details, see Chapter 16, Command Line Reference, in Oracle GlassFish Server Message Queue 4.5 Administration Guide for details. The Message Queue graphical user interface (GUI) administration tool, the Administration Console, also includes a context-sensitive help facility; see the section “Administration Console Online Help” in Chapter 2, Quick-Start Tutorial, in Oracle GlassFish Server Message Queue 4.5 Administration Guide.
