API exits

 

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. The insertion is automatic; the queue manager drives the exit code at the registered points.

This chapter explains why you might want to use API exits, then describes what administration tasks are involved in enabling them. The sections are:

• Why use API exits

• How you use API exits

• What happens when an API exit runs?

• Configuring API exits

We give a brief introduction to writing API exits in How to write an API exit. For detailed information about writing API exits, aimed at application programmers, see the WebSphere MQ Application Programming Guide.

• Why use API exits
  

• How you use API exits
  

• What happens when an API exit runs?
  

• Configuring API exits
