JMS and Java Client Mode Performance Issues for MQ Get API Calls
I’ve wasted far, far too much of my time inspecting what is going on with the auto-resizing of the get buffer for the internal JMQI and MQI components for MQ classes for JMS, MQ classes for Java and MQ classes for .NET. A strange entry in one of the MQ Auditor audit files got my […]

Pub/Sub Java/JMS MQ MQGet API Issue
Not surprisingly, when I tested: Subscribing to a topic with JMS Subscribing to a topic with Java (non-JMS) They both showed that the internal JMQI routine was starting with a MQGet buffer size of 4KB and auto-adjusting the size of the buffer as needed (all behind the scenes). Hence, when I used MQ Auditor, I […]

Tuning Java Programs for Optimum MQ Get API Calls Performance
You should really read this blog posting first. The results of some of the test scenarios below, simply do not make any sense. I would like to think there is some sort of logic behind it but it is probably lack of testing by IBM that introduced some bugs in the code or should I […]

Tuning JMS Programs for Optimum MQ Get API Calls Performance
On Wednesday, I decided to do some testing of some simple (1) MQ for JMS, (2) MQ for Java and (3) procedure language (i.e. amqsbcg) programs to show that using the JVM environment variable of com.ibm.mq.jmqi.defaultMaxMsgSize with an appropriate size could make a JMS application 10 to 15% faster because there would not be any […]
