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.

Dropping LZ1 support from MQ Message Compression

I have been doing a lot of a testing of various messages types (i.e. Fixed-width, CSV, XML, JSON, PDF, PNG, JPG, etc.). I’ll post the results in the next blog posting. I have decided to drop support for LZ1 compression algorithm from MQ Message Compression (MQMC) for the following reasons: LZ1 has the slowest compression […]

Microsoft Screwed Me Again

On Tuesday, Windows 10 Pro said that my current release of Windows 10 (I believe it was 1904) was going out of support and I needed to upgrade to release 2004. Against my better judgment, I allowed it to proceed when I went to bed Tuesday night then the problems started on Wednesday (yesterday). What […]

How to (Properly) Setup ASUS AiMesh

One thing always leads to another! In my house (and home office), I had an ASUS RT-AC68U router (on main floor) and a Tenda W150M router (in basement). Once in a while, someone would complain that the ‘internet is not working’ or ‘internet sucks’! Sometimes it would be as simple as being on the wrong […]

Capitalware is ready for beta testers for a new solution called: MQ Message Compression (MQMC). MQMC is an MQ API Exit. Question: Would you trade a little CPU time to drastically reduce the disk I/O time? I have written a long blog posting on the internals of queue manager logging (with help from Chris Frank) […]

Compression, What’s It Good For?

September 4, 2020 Roger Lacroix
s

Well, to answer my own question, you want Netflix, Hulu, etc. to use compression when you stream movies or TV shows. Or compress files to free up disk space. There are a variety of reasons to use compression. I’ve been doing a lot of testing using large files and it got me thinking about the […]

Enhancement to MQMR

September 2, 2020 Roger Lacroix
s

Capitalware has an MQ solution called MQ Message Replication (MQMR). MQ Message Replication will clone messages being written (via MQPUT or MQPUT1 API calls) to an application’s output queue and MQMR will write the exact same messages to ‘n’ target queues (‘n’ can be up to 100). When MQMR replicates a message both the message […]

Earlier this year, IBM shutdown its IBM PDP (Power Development Platform), originally called IBM VLP (Virtual Loaner Program), and replaced it with IBM CECC (Client Experience Centers Cloud). IBM does loves their acronyms! I appreciate IBM supplying virtual VMs for developers to use to port their applications to AIX, IBM i and Linux on POWER, […]

I have created a new section on Capitalware’s IBM MQ Documentation Library page called Redbooks on IBM MQ. I searched the internet and IBM’s Redbook site and found 20 redbooks on the subject of IBM MQ (formally WebSphere MQ, MQSeries). I have listed them in chronologically order. Note: Some of them may be old but […]
