Use the API-crossing exit

 

We can use the API-crossing exit to:

• Operate additional security checks by examining the contents of each message before and after each MQI call

• Replace the queue name supplied in the message with another queue name

• Cancel the call and either issue a return code of 0 to simulate a successful call, or another value to indicate that the call was not performed

• Monitor the use of MQI calls in an application

• Gather statistics

• Modify input parameters on specific calls

• Modify the results of specific calls

• Defining the exit program
  

• How the exit is invoked
  

• Communicating with the exit program
