My name is Roger Lacroix and I am a die hard programmer. I have been programming since the 80s. My favorite programming languages are Java, C and Rexx. I have worked in the Airline, Retail but I have spent most of my time doing middleware work in the financial services industry. In 1994, I was introduced to IBM MQ (aka WebSphere MQ & MQSeries) and I thought it was the next best thing since man created fire. This blog will be about IBM MQ, Java, C, Rexx and any other interesting items that I can think of. I hope you enjoy it.

Talk about spending several days chasing my tail. šŸ™ I have a customer who build a brand new Windows 2016 Server and install IBM MQ v9.1 then applied Fix Pack 2. So, they were at MQ v9.1.0.2. Next, they installed MQAUSX and applied their generic definitions to it. So far, so good. But when they […]

Architecture of the exit library does not match the process’s architecture which is ’64’ bit. MQAUSX is just an example, as it could happen with […]
