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.

Enhancement to Exporting MQ Objects into Individual Files

March 11, 2021 Roger Lacroix
s

Yesterday, I wrote a blog item regarding Exporting MQ Objects into Individual Files. I forgot that the dmpmqcfg program can output the MQ Object information as 1 line rather than spanning multiple lines. Hence, if we let dmpmqcfg do that work then we can simplify the Rexx script to only output the various MQ objects […]

Ok. Here’s a really weird one reported yesterday by a customer. If you are using a MacBook Pro with an external monitor (or 2) via Display Link and you try and run a Java GUI application, it will crash because the JVM thinks that it is running on a headless computer (no graphics driver). Therefore, […]

Exporting MQ Objects into Individual Files

I posted this item on mqseries.net and I thought I should do a write up here. Back in the early 2000s, I was a consultant at a customer site and they wanted the nightly dumps of the MQ objects (not messages), 1 line per object and then check those files into a source code repository. […]

Morag Hughson of MQGem has a new blog posting called IBM Knowledge Center – LATEST! regarding a new feature in the IBM Knowledge Center.
