Posted on November 28, 2021 by António Trindade

This should prob­a­bly be my first blog post about MQ, but I con­fess: I was too excit­ed to start writ­ing. Late­ly I’ve had lit­tle time to post new stuff. This is prob­a­bly just an excuse to write some­thing again. In the … Con­tin­ue read­ing →

Posted on August 17, 2019 by António Trindade

It is fre­quent­ly neglect­ed. It is almost always over­looked. It is the ugly duck­ling of dis­trib­uted appli­ca­tion design. Yes, I am talk­ing about Infor­ma­tion Secu­ri­ty. Secu­ri­ty should be a com­pul­so­ry require­ment of any appli­ca­tion. IBM MQ has exten­sive secu­ri­ty options … Con­tin­ue read­ing →

IBM MQ basics: remote queues and channels

Posted on April 14, 2019 by António Trindade

In the first install­ment of the IBM MQ Basics, avail­able here, I showed you basic queue cre­ation and usage. If IBM MQ would only allow local queues to be cre­at­ed and used, it would be less use­ful. One of the strengths … Con­tin­ue read­ing →

Posted on December 27, 2018 by António Trindade

I’ll start this blog with a piece of soft­ware I’ve been learn­ing in the past few months: IBM MQ.  Mes­sage queu­ing is a dis­trib­uted inter-process com­mu­ni­ca­tion method based on mes­sage pass­ing.
