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.

Well, there went 2 days of my life I won’t get back. 🙂 About 2 weeks ago, when I booted up my SLES 64-bit Linux server, it complained about issues with the hard drive. So, I ran “fsck” to fix the file system issues. There was only a couple of problems then everything was fine. […]

Google is a great search engine. When I search for “ftime linux”, the first search hit will be the man page for ftime which is exactly what I wanted. But sometimes I just want the whole manual in PDF format so that I can simply read about functions and scroll through it while I’m trying […]

More RSS Sidebar MQ Content on my Blog

March 7, 2019 Roger Lacroix

You may have noticed for a couple of weeks that the “IBM MQ” content sidebar was not showing anything. That is because IBM again changed the link. IBM doesn’t publish the information and they love to change it every so often, so for me it is like a game of whack-a-mole. Someone sent me the […]

Weird Problem related to a Channel Security Exit

I posted the following weird channel security exit problem on the MQSeries ListServer. I received a lot of emails (both public and private) offering help to the problem. Thanks. It was not an SELinux issue nor was it a corrupt shared library issue. It was an issue related to permissions for a mount point. Here […]

He said that the MQ Knowledge Center recommends for distributed queue managers a value of 1 for a channel’s SHARECNV. Of […]

Someone on StackOverflow asked “How to compile a C program without knowing the include files”. JasonE gave a really good answer, so I thought I would repeat it here: To compile and link 64-bit MQ applications on Linux, follow the instructions here To compile and link 32-bit MQ applications on Linux, follow the instructions here […]
