Redbooks on IBM MQ

July 24, 2020 Roger Lacroix

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 […]

Simple Monitoring of the Current Queue Depth

June 4, 2020 Roger Lacroix

On StackOverflow, someone asked a question about determining when a queue’s current depth is the same as maximum depth. They were trying to do it from a script. While this is probably possible (I’m not a sed and/or awk guy), it seemed to me that they are trying to squeeze a fully blown up balloon […]

IBM MQ, Java and MQ MI and/or MQ HA

April 8, 2020 Roger Lacroix

Sometimes you come across things that make you just scratch your head and say who the hell wrote this @#$% code. I’m not trying to say that I’m the world’s greatest programmer but some of the shit that the MQ/Java team writes just makes my head spin. They need to share what they’re smoking! IBM’s […]

Java’s Missing Byte Array Class

February 19, 2020 Roger Lacroix

After 25 years, it is still surprising that Java doesn’t have a proper byte array class. There can be many reasons that the data a Java program needs to work with is in a byte array. It could be the contents of a file or MQTT message or IBM MQ message, etc. Since there is […]

Request & Reply JMS/MQRFH2 Messaging Scenario

January 31, 2020 Roger Lacroix

Sometimes people over think a problem and write a complicated solution when really the solution is no different than any other Request/Reply scenario (use case). On StackOverflow, someone asked a question about sending a reply JMS/MQRFH2 message using the RFH2 header and folder values from the original request message. The code will copy the RFH2 […]
