MSMQ from the plumber's mate

To really get into the right mind-set for discussing MSMQ's limits I think we should first read the words of that great man Douglas Adams : "Space is big - really big - you just won't believe how vastly, hugely mind-bogglingly big it is. You may...

This is sort of defeating the main point of using MSMQ - that is, being able to send a message without worrying if the destination is available or not - but there may be a good business reason for wanting to. Just because a machine is on-line does...

For some reason I missed the article appearing on the MSMQ product group's blog a couple of weeks ago discussing using LINQ and system.messaging together: Combining LINQ with System.Messaging Patrick Toolis of the MSMQ test team has written...

If you are doing some testing and want to enable journal messages so you can track what's going on, make sure you know what sort of journaling you've picked because there are two types: Source journaling Target journaling Positive Source...

Just noticed that "Queue" in French means a variety of things : A queue of people (as you'd guess) The tail of an animal (such as a dog) Slang for a man's sexual organ which puts a number of support cases I have worked on with French customers...

[[Updated 6th October 2008 to add KB198893]] Just a quick post about one of the main gotchas. A common misunderstanding can be over which MSMQ service is doing the work. On a simple 2-node MSMQ cluster there will be three instances of MSMQ: ...

Nine times out of ten this will not be the correct question. Whoever is asking REALLY means "How do I send MSMQ messages between forests?" MSMQ will happily send messages between domains in the same forest. All you need is a Global Catalogue (GC) in...

There are a number of areas that affect MSMQ performance (memory, CPU, network) but for this post I'll just concentrate on disk throughput. MSMQ uses a lot of disk I/O when you are requesting transactional or recoverable messaging. Not only do the...

I'm now the proud owner of a working Windows Server 2008 installation (I know, I know, I should have got into the beta but I've been busy..) so I thought I'd have a quick look at what's different in Computer Management. You'll be happy to know that little...

[[This post applies to traditional MSMQ messaging rather than sending MSMQ messages over HTTP. With the latter you just create a mapping file and you're good to go.]] The scenario is that one of your MSMQ servers has had a hardware failure and is down...

I've been looking through the online Resource Kit to read up on the MaxUnackedPacket registry value and found some really unhelpful documentation for it so I thought I should explain what's really going on in case people try to use the ResKit's information...

Windows Server 2008 comes with an option to install just the bare components necessary, something customers have been asking for for many years. I quote from MSDN : "Server Core is a minimal server installation option for computers running on...

Had a support problem recently which took a while to crack and thought I'd share. The customer had a Trigger on a queue that would peek (but not receive) the message. At the end of the day all the messages would be manually purged ready for the next...

Everything starts here at the MSDN Library - documentation, concepts, tutorials, primers, guideliness, best practices, troubleshooting, glossary and so on. Don't miss the samples under the "Samples (.NET Framework Technologies)" branch. Michele Leroux...

Soon you'll be able to run MSMQ 4.0 on both server AND workstation. So to review, for those who haven't been looking at MSMQ 4.0 since Vista came out over a year ago, here's " what's new ": Transactional Remote Receive This is the biggy - pull...

Just a quick post to bring together some MSDN webcasts that you may want to have a look at if you're interested in using MSMQ or WCF (and maybe both). MSDN Webcast: Using Asynchronous Patterns with Web Services "Asynchronous communication patterns...

Back in November , I mentioned that the Hands-On Lab would be available at the end of 2007. Well, it's only a month late :-) So if you are intersted in " SOA'izing MSMQ with WCF (and Why It's Worth It) " Microsoft Message Queuing’s (MSMQ) integration...
