THE COMPLETE GUIDE
ActiveMQ is popular. But how does ActiveMQ work? And how can you make it work even better?
Consider this your guide to how ActiveMQ works.
We’ll cover everything you need to know about ActiveMQ. This includes an overview of message brokers, guides to ActiveMQ monitoring, tips for ActiveMQ high availability, and so much more.

ActiveMQ works by sending messages between disparate applications.
ActiveMQ is a popular open source messaging service written in Java. It’s a type of message-oriented middleware, made up of Apache ActiveMQ brokers and application clients, called producers and consumers. ActiveMQ isn’t the only open source message broker.
There are other open source message brokers, including RabbitMQ and Kafka. There are pros and cons to all of these. ActiveMQ is known for being a mature and well-adopted platform with 1,000s of companies already using it. ActiveMQ is also the most feature-rich open source message broker available.

ActiveMQ is a deceptively complex piece of software. Here are some tips to help you get the most out of using ActiveMQ.
ActiveMQ creates queues on-demand by default. Destinations are created in the broker any time a client asks to utilize that destination, regardless of whether it already existed. There are some issues with this which can even lead to downtime. Disabling the dynamic ActiveMQ queue can help you avoid the risks.
High availability (HA) is important for ActiveMQ. It’s critical that your brokers stay up and running at all times.
In order to ensure HA, you’ll need to configure your brokers for failover. If you’re configuring for failover with JDBC persistence, you’ll want to use connection pooling with c3p0 to optimize throughput to your persistence journal.
ActiveMQ creates small, short-lived objects inside the JVM. This can lead to memory fragmentation and other compaction issues. So, you’ll really want to be mindful of Java’s garbage collection when administering ActiveMQ. G1GC is the best current garbage collector option for ActiveMQ.
Monitoring is critical to ensure that ActiveMQ stays healthy. There are tools you can use with ActiveMQ to monitor resource usage, queue depths, and other message behavior. To extend that monitoring further, ActiveMQ comes with a robust set of JMX metrics which can be accessed using a range of common monitoring utilities and platforms.
The performance of ActiveMQ can vary greatly depending on the data throughput needs of your business, the size of your data payloads, and more. That’s why it’s important to improve performance through regular troubleshooting and performance tuning. Running performance tests and keeping an eye on metrics can help.

Open source middleware like ActiveMQ needs to be backed by support.
That’s because ActiveMQ bridges the gap between different applications, providing a messaging service. If ActiveMQ isn’t set up correctly — or if it fails — it could be catastrophic to your business, cascading problems down to all areas of the infrastructure.
But if you enlist support for ActiveMQ, you can get the best of both worlds:
It’s important to find a vendor who has expertise in ActiveMQ — and can support your full stack of open source tools. OpenLogic has experts skilled in ActiveMQ, who understand the interoperability between applications. Our experts can help you set up ActiveMQ correctly. And they can help you resolve issues and make sure your open source stack runs smoothly.
