I wanted to know whether DevTest supports WebSphere MQ 9 as there is no WebSphere MQ File Requirements are given for WebSphere MQ version 9 in documentation.
If yes, does the file requirements remain same as WebSphere version 8?
At present, the answer is "no". However, MQ 9 is currently being actively tested in anticipation of future support.
Engineering has stated "it'll probably work". However, until it can be thoroughly evaluated, it's not, yet, officially supported.
