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.
This book helps you configure and use active messaging in Adaptive Server database applications.
Chapter 1, “Introduction,” discusses messaging concepts, models, and formats.
Chapter 2, “Understanding Active Messaging,” is an overview of Active Messaging that is specific to Adaptive Server.
Chapter 3, “SQL Reference,” documents the SQL stored procedures, functions, and global variables for managing and administering real-time messaging, and the general format of option strings.
Chapter 4, “Samples,” provides code samples that illustrate messaging functionality.

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.
You 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.

Each Sybase installation that has purchased a support contract has one or more designated people who are authorized to contact Sybase Technical Support. If you cannot resolve a problem using the manuals or online help, please have the designated person contact Sybase Technical Support or the Sybase subsidiary in your area.
