Special subqueues Each Azure Service Bus queue has several subqueues. There’s no possibility to create your own custom subqueue like you can in MSMQ. Also, there’s no journal like we have in MSMQ to keep all received messages (if turned on). There are no outgoing nor 3 system MSMQ queues. Let’s see what we do have. […]

Topics and subscriptions – Azure Service Bus for MSMQ users, Part 2
Topics and their subscriptions represent publish-subscribe (pub-sub) messaging pattern. If you’re coming from MSMQ, that’s a new concept. What’s the difference to plain old queue? Simplest scenario for a queue (and arguably most common one) is – single sender and single receiver: Of course, we could have multiple senders, but that doesn’t create problems unless we want to […]
Introduction to Azure Service Bus for MSMQ users, Part 1
This series of blog posts is intended for those who already have some MSMQ experience and would like to know more about Azure Service Bus.

QueueProxy on MSMQ cluster
Managing clustered MSMQ was always tricky, since it runs as a separate instance, i.e. more or less like a separate “virtual” computer with MSMQ installed. When you try to manage it from QueueExplorer you’ll see that there are some limitations since it’s done in remote mode, either from one of cluster nodes or from some other […]
MSMQ Heartbeat checks with QueueMonitor
Here’s how wikipedia describes heartbeats in computing: In computer science, a heartbeat is a periodic signal generated by hardware or software to indicate normal operation or to synchronize other parts of a computer system. How can we apply heartbeats to MSMQ? We can start with simple heartbeat checks – QueueMonitor sends message to a queue, […]

QueueMonitor since version 1.5.9 can be installed on a Windows Server cluster as clustered application. Main addition to v1.5.9 release was ability to put QueueMonitor’s data folder on shared Cluster storage. That way there will be single shared task database used by both nodes.

QueueExplorer 4 is finally available for Beta testing. It’s been a long wait but not without a reason. It was overhauled to support multiple queueing systems, and for start we added support for ActiveMQ. There are lot of improvements for MSMQ users as well.

Automatically resend expired MSMQ dead letter messages using QueueMonitor
There were few inquires recently on what to do with messages which were moved by MSMQ to dead letter queue because they reached “Time to be received” timeout. When is Time to be received property useful? Sometimes messages are of temporary value and are not important unless they are processed immediately. For instance if we use queue […]
