Have any changes been made since the last successful run?

 

When you are considering changes that might recently have been made, think about the WebSphere MQ system, and also about the other programs it interfaces with, the hardware, and any new applications. Consider also the possibility that a new application that you are not aware of might have been run on the system.

• Have you changed, added, or deleted any queue definitions?

• Have you changed or added any channel definitions? Changes might have been made to either WebSphere MQ channel definitions or any underlying communications definitions required by your application.

• Do your applications deal with return codes that they might get as a result of any changes you have made?

• Have you changed any component of the operating system that could affect the operation of WebSphere MQ? For example, have you modified the Windows Registry.
