About this book

Audience

This book describes how to use Active Messaging to capture transactions (data changes) in an Enterprise Edition or Cluster Edition Adaptive Server® Enterprise database and deliver them as events to external applications in real time. These data changes—or events—are delivered to applications through a Java Messaging Service message bus such as EAServer Java Messaging Service (JMS), Tibco Enterprise Message System (EMS) or IBM WebSphere MQ.

Accessibility features

This document is available in an HTML version that is specialized for accessibility. You can navigate the HTML with an adaptive technology such as a screen reader, or view it with a screen enlarger.

Adaptive Server HTML documentation has been tested for compliance with U.S. government Section 508 Accessibility requirements. Documents that comply with Section 508 generally also meet non-U.S. accessibility guidelines, such as the World Wide Web Consortium (W3C) guidelines for Web sites.

NoteYou might need to configure your accessibility tool for optimal use. Some screen readers pronounce text based on its case; for example, they pronounce ALL UPPERCASE TEXT as initials, and MixedCase Text as words. You might find it helpful to configure your tool to announce syntax conventions. Consult the documentation for your tool.
