Java/PCF Program to Create an IBM MQ SVRCONN Channel

May 18, 2022 Roger Lacroix

A couple of weeks ago, I posted a Java/PCF Program to Create an IBM MQ Queue. So, today I thought I would create a Java/PCF program to create an IBM MQ SVRCONN channel If you are used to creating an IBM MQ channel using runmqsc command then the following simple Java/PCF program will create a […]

Java/PCF Program to Delete an IBM MQ Queue

May 5, 2022 Roger Lacroix

A couple of days ago, I posted a Java/PCF program that would create a IBM MQ queue. So, if you require creating a queue via Java/PCF then you probably will need to delete a queue via Java/PCF. If you are used to deleting an IBM MQ queue using runmqsc command then the following simple Java/PCF […]

Java/PCF Program to Create an IBM MQ Queue

May 3, 2022 Roger Lacroix

The other day, someone on StackOverflow asked about creating an IBM MQ queue from JMS. I know it is possible to send PCF commands as a JMS message to the Command Server but it seems overly complex when you can simply do it from Java/PCF (non-JMS). If you are used to creating an IBM MQ […]

Updated SimpleLogger Class

December 22, 2021 Roger Lacroix

The other day, someone emailed me and asked if I could add code to externalize the default values used by the SimpleLogger Class. I thought about it and figured it would be reasonably straight forward. Hence, here are the JVM Environment variables that the SimpleLogger Class supports: SimpleLogger.LogFileName – any valid file name SimpleLogger.LogDirectory – […]

My SimpleLogger can be a Replacement for Log4J

December 16, 2021 Roger Lacroix

In this blog post, don’t get me wrong, I think Log4J is a great product and I am not trying to discourage anyone from using it. I have used Log4J v1.x on hundreds of projects for customers and myself. It has always worked exactly as expected. I have never used Log4J v2.x, so I cannot/will […]

Log4J Vulnerability And Capitalware Products

December 11, 2021 Roger Lacroix

For those who have not heard, there is a new vulnerability in Log4J v2.x. Here is a link to the Log4J v2.x vulnerability: https://unit42.paloaltonetworks.com/apache-log4j-vulnerability-cve-2021-44228/ The Log4J v2.x vulnerability is related to the ‘lookups’ feature that was introduced in version 2. Lookups provide a way to add values to the log4j configuration at arbitrary places. They […]

And Now for Something Completely Different.

November 9, 2021 Roger Lacroix

I love that line from Monty Python which is from the film of the same name. Last week, someone emailed me about running MQ Visual Edit on Microsoft Surface Pro X. For those who don’t know, the Surface Pro X comes with a Microsoft SQ1 or SQ2 ARM processor. Yes, ARM CPU and not an […]
