Chapter 6. Introducing the Message Queue Interface

This chapter introduces the features of the Message Queue Interface (MQI).

The remaining chapters in this part of the book describe how to use these features. Detailed descriptions of the calls, structures, data types, return codes, and constants are given in the WebSphere MQ Application Programming Reference.

The MQI is introduced under these headings:

Note
The Application Messaging Interface (AMI) provides a simpler and higher-level programming interface than the MQI. Although it has some limitations compared with the MQI, its function should be sufficient for the majority of users. The AMI supports both point-to-point and publish/subscribe messaging models, and includes support for both WebSphere MQ Integrator Version 1 and WebSphere MQ Integrator Version 2. The AMI eliminates the need for application programmers to understand all of the options and functions available in the MQI. The Application Messaging Interface for C, C++, and Java runs on the following operating systems or environments: OS/400, AIX, HP-UX, Solaris, Microsoft Windows, and z/OS. The Application Messaging Interface for COBOL runs on the z/OS operating system. Further information about the AMI is outside the scope of this book. For full details, refer to WebSphere MQ Application Messaging Interface.
