Introducing API exits

 

Not supported on WebSphere MQ for z/OS.

API exits let you write code that changes the behavior of WebSphere MQ API calls, such as MQPUT and MQGET, and then insert that code immediately before or immediately after those calls. Once you have written an exit program and identified it to WebSphere MQ, the queue manager automatically invokes your exit code at the registered points.

This chapter tells you how to write API exits, and how to set up WebSphere MQ to enable them. This section explains how you might use them and introduces the tasks involved. This chapter also contains the following major sections:

• Compiling API exits

• Reference information

• Why use API exits
  

• How you use API exits
  

• What happens when an API exit runs?
