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.

JMS/MQRFH2 Message Properties in “other” Folder

January 17, 2020 Roger Lacroix
s

On StackOverflow, someone asked about having an “other” folder (not “usr”) with an MQRFH2 (aka JMS) message. That day, I played around with a MQ/Java program that created various folders in an MQRFH2 message. i.e. When I ran a MQ/JMS program to retrieve the messages, the MQ/JMS programs simply ignore all folders outside of ‘mcd’, […]

IBM likes to market IBM MQ (aka WebSphere MQ, MQSeries) as a simple and complete solution for business’s messaging needs. Going with the KISS approach is wise (very wise in some cases). IBM talks about the 2 different messaging models that IBM MQ supports: Point-to-Point (P2P) and Publish/Subscribe (Pub/Sub). IBM will: show you how to […]

MQME Issue with ExcludeQueue keyword on an MQPUT1 API Call

December 9, 2019 Roger Lacroix
s

Late last week, a customer discovered an obscure issue in MQ Message Encryption (MQME) with the ExcludeQueue keyword on an MQPUT1 API call. I have since fixed it but here is what I mean by obscure: – If the user has wild-carded their protected queue setup i.e. ‘TEST.*’ – And then set the ExcludeQueue keyword […]

I use IBM’s Remote Development Program (RDP) to host my z/OS and Linux for System z LPARs. I installed the latest release of wc3270 of the x3270 project on my new Windows 10 PC and copied my settings from my old Windows 7 PC. Hence, I should be good to go but no. I have […]
