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.

Customer Requested Updates to MQMR

January 22, 2019 Roger Lacroix
s

MQ Message Replication (MQMR) is an MQ API Exit. An MQ API Exit is configured to run within the queue manager’s address space (or the application’s address space if the application connects in bindings mode to the queue manager). I designed MQMR to be extremely light-weight when replicating messages to target queues. MQMR determines if […]
