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

March 1, 2019 Roger Lacroix

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 […]

Best Practices for an IBM MQ Channel’s SHARECNV Parameter

March 1, 2019 Roger Lacroix

I was chatting with Josh the other day and he asked me if I knew that IBM now does not recommend uses the default value of 10 for a channel’s SHARECNV (shared conversation) value. He said that the MQ Knowledge Center recommends for distributed queue managers a value of 1 for a channel’s SHARECNV. Of […]

RIP: MQ Technical Conference

February 19, 2019 Roger Lacroix

Capitalware Inc. is a small software company specializing in IBM MQ. Capitalware used to be a vendor at IBM’s Transaction and Messaging Technical Conferences (T&M Conference). IBM merged several conferences including the T&M Conference into Impact 2007. I went as a vendor to Impact 2007 but found that most attendees were not involved in MQ. […]

How to Compile and Link MQ Programs on Linux

February 13, 2019 Roger Lacroix

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 […]

IBM MQ macOS toolkit for developers

February 7, 2019 Roger Lacroix

IBM releases IBM MQ macOS toolkit for developers. I’m shocked and wildly surprised that IBM did this. https://developer.ibm.com/messaging/2019/02/05/ibm-mq-macos-toolkit-for-developers/ This toolkit provides the ability to develop and interact directly with MQ from your Mac, for developers using the language interfaces; such as C, C++, COBOL, GoLang, and Node.js; which are built on the platform-native C library […]

Customer Requested Updates to MQMR

January 22, 2019 Roger Lacroix

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 […]

Customer Requested Updates to MQCCI

January 7, 2019 Roger Lacroix

In December, I had a call with a potential customer regarding MQ Channel Connection Inspector (MQCCI). Their security concerns were similar to what I posted several months ago in “So You Secured MQ But How Do You Know It Is Secure?“. During the discussion, they brought up a couple of interesting comments: How to correlate […]
