A few months ago, I received a number of complaints from Mule customers about strange freezes that they couldn’t trace to any cause.  When I investigated, I noticed something – all of these customers were using ActiveMQ.

I dug a little deeper, and found that the freezes were being caused by a flaw in the way that ActiveMQ behaves when its message queue becomes full.  Mule wasn’t freezing – it was waiting for ActiveMQ!

Using Mule MQ, which uses a return status to handle full queue situations, I was able to write up a quick alternative configuration that solved the problem, routing messages to a dead.letter queue for re-use if the default queue became full.

Are you looking for a  JMS messaging solution that can be deployed and supported with Mule ESB, or as a standalone messaging platform?  Are you looking for better performance, stability, management and scalability than ActiveMQ but without the complexity or cost of WebSphere MQ or TIBCO EMS?

On Wednesday May 26, Ken Yagen, VP of Engineering, and Mateo Almenta Reca, Sr. Product Manager, will host a webinar about Mule MQ, featuring a live demonstration of Mule MQ’s powerful and intuitive administration console, including:

• Setting up a JMS cluster in 5-minutes
• Inspecting in-flight JMS messages for troubleshooting
• Fine tuning Mule MQ to meet your performance requirements

Date: May 26th, 2010
Time: 10am PT / 1pm ET
Duration: 45-minutes

We have received a great early response so far to our recent release of Mule MQ, MuleSoft’s new JMS messaging server.  The response is not unexpected, since the Mule ESB user base has been requesting that we provide a JMS server which has been tested and is supported along with Mule ESB.  Hundreds of organizations have downloaded Mule MQ for evaluation and we have been hearing great feedback from the Mule community.

Some people have been very interested in the performance of Mule MQ, and they have asked us to provide more details about the tests we have run to validate performance. It’s clear that performance is one of the most important criteria for selecting a JMS messaging product, so our product team spent a great deal of time benchmarking Mule MQ against the most popular JMS products currently available.

One of the projects we selected for comparison was Apache ActiveMQ (most product vendors prohibit publishing benchmark data). ActiveMQ is the leading open source JMS technology, and is popular with the Mule community. For that reason, we wanted to understand how Mule MQ would compare ActiveMQ under some common scenarios.

A few things that we considered as we designed our tests:

MuleSoft just announced availability of Mule MQ.

Seriously! Do we really need another messaging server in this already crowded market? Then again, do we really need Google Nexus One and Motorola Droid when Apple’s iPhone supposedly already has almost everything one could ask for? The answer lies in the user’s need for reliability, performance, interoperability, and ease of use – in short, the answer is YES. (more…)
