Copying Messages Like a Pro with IBM MQ

Hi there MQ admin! I‘m thrilled to see you taking time to level up on maximizing IBM‘s robust messaging platform. As channels of communication get increasingly complex, you play a crucial role in piping data between systems to power digital business. This article will equip you with expert techniques to seamlessly copy messages between queues. Read on!

Why Message Queues Matter More Than Ever

First, let‘s get grounded in why message movement presents high stakes these days:

As seen above in the explosion of messaging adoption, applications simply cannot handle the diversity of workloads in a coupled fashion anymore. Enterprises urgently need asynchronous decoupling.

This allows flexible scaling, reduces bottlenecks, and enables resilience across domains:

However integrations multiply, the fundamental building block remains reliable message delivery.

Common Pain Points Admins Face

Juggling the dynamic demands of messaging infrastructure brings no shortage of battle scars! Based on surveys of admins worldwide, these three challenges topped the list:

  • Downtime – Even brief outages cause catastrophic business disruption
  • Security – Increased attack surface from interconnections
  • Agility – Change management overhead to alter existing flows

Let‘s conquer them together!

Preparing Your MQ Environment

Before marching ahead with message copying quests, let‘s quickly validate key prerequisites:

Queues – Create required queues upfront:

DEFINE QLOCAL(‘MY.SOURCE.QUEUE‘)  
DEFINE QLOCAL(‘MY.TARGET.QUEUE‘)

Verify with display commands:

DISPLAY QSTATUS(MY.SOURCE.QUEUE) 
- 5 MESSAGES AVAILABLE

Feel free to tweak parameters to your use case!

With that foundation set, you now have messages ready for transport…

dmpmqmsg – Quick Copy Shell Wizardry

Our journey commences with the simplest route – using built-in tooling that requires no new software or recompiling code! Let‘s run through example using dmpmqmsg:

dmpmqmsg Flow

This utility handles all the heavy lifting of establishing queue manager connections, getting messages from source, and putting to target destination.

Invoke with:

dmpmqmsg -m QM1 -i MY.SOURCE.QUEUE -o MY.TARGET.QUEUE

Review parameters:
