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.

A general rule is that your password should be at least 11 characters and use numbers, along with upper and lowercase letters. That combination will take hackers 41 years to crack. Here’s […]

MQ Request/Reply Scenario with Async Getter Thread

July 8, 2021 Roger Lacroix
s

Ok. Continuing on with the previous blog posting here, the StackOverflow user says that s/he wants the getter component to be run in a separate thread. To me, the request does not really make a lot of sense. If the user wants to do a Get with CorrelId then they should be coding for synchronous […]
