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.

MQ Auditor’s new Audit Queue Off Load Application

May 10, 2012 Roger Lacroix
s

I am always looking to tune Capitalware’s applications . After reviewing MQ Auditor, it occurred to me that I could save 8-12 ms (milliseconds) per audit record that MQ Auditor writes to the audit files. Now, 8-12 ms per audit record may not sound like a lot but if your queue manager is processing a […]
