memmem() Function for a C Program

March 17, 2020 Roger Lacroix

Last week, I needed a function for a C program that would search a string not null terminated for a string not null terminated. Hence, I could not use strstr() function because it requires the strings to be null terminated. So, I checked my trusty C Runtime Library Reference and found nothing that matched. Now […]

JMS/MQRFH2 Message Properties in “other” Folder

January 17, 2020 Roger Lacroix

On StackOverflow, someone asked about having an “other” folder (not “usr”) with an MQRFH2 (aka JMS) message. That day, I played around with a MQ/Java program that created various folders in an MQRFH2 message. i.e. When I ran a MQ/JMS program to retrieve the messages, the MQ/JMS programs simply ignore all folders outside of ‘mcd’, […]

MQ Internals Explained (a little bit)

December 10, 2019 Roger Lacroix

IBM likes to market IBM MQ (aka WebSphere MQ, MQSeries) as a simple and complete solution for business’s messaging needs. Going with the KISS approach is wise (very wise in some cases). IBM talks about the 2 different messaging models that IBM MQ supports: Point-to-Point (P2P) and Publish/Subscribe (Pub/Sub). IBM will: show you how to […]

AMQ7234 Question from the MQ ListServer

November 20, 2019 Roger Lacroix

Doug posted a question on MQ List Server regarding the MQ error message AMQ7234. His question was: My shop has always struggled with large number of messages just being left on the queue. Sometimes to be processed later, sometimes because the application does not know what to do with them, but they cannot be removed. […]

Oh Error Messages, Why Can’t You Say What You Mean?

June 11, 2019 Roger Lacroix

Talk about spending several days chasing my tail. 🙁 I have a customer who build a brand new Windows 2016 Server and install IBM MQ v9.1 then applied Fix Pack 2. So, they were at MQ v9.1.0.2. Next, they installed MQAUSX and applied their generic definitions to it. So far, so good. But when they […]
