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.

A general rule is that your password should be at least 11 characters and use numbers, along with upper and lowercase letters. That combination will take hackers 41 years to crack. Here’s […]

Last week, a customer emailed an interesting request. They have 2 AIX hub servers running WebSphere MQ V6.0 and they want to determine what applications are using the 2 MQ hub servers, so that they can upgrade to a newer release of MQ. That made me clean my glasses because MQ v6 went out of […]

MQ Request/Reply Scenario with Async Getter Thread

July 8, 2021 Roger Lacroix
s

Ok. Continuing on with the previous blog posting here, the StackOverflow user says that s/he wants the getter component to be run in a separate thread. To me, the request does not really make a lot of sense. If the user wants to do a Get with CorrelId then they should be coding for synchronous […]

Capitalware Product Advisory – MQ Auditor

June 25, 2021 Roger Lacroix
s

A bug was discovered in Capitalware’s MQ Auditor related to PCF response message for the PCF MQCMD_INQUIRE_Q_NAMES command. The PCF response message to the MQCMD_INQUIRE_Q_NAMES command has 2 parts: list of queues and list of queue types. To format the queue types (i.e. local, alias, etc.), the code used a 1024 byte static array. The […]
