IBM: ‘Mac users are happier and more productive’

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 […]
