Earlier in the year I wrote an article talking about the hot topics in WebSphere MQ (WMQ). I thought now would be a good time to take another look and see what has changed. I found a lot of the things that were hot then are still hot now. So in this article, I am not going to talk much about the items included in the last article. Instead, I will list 5 new items that I did not include in my list the last time. In case you missed the first article you should go back and take a look at that because many of those items are still hot topics... [More]

Well, well. You have installed WebSphere MQ onto your system.  Now, you need to determine whether you installed the client or server.  It could be that you need to determine this after you installed it 2 years ago and you just don’t remember.  Better yet, you need to ensure that you have the proper number of licenses for every WebSphere MQ server installed.
