Charan: Hey Rohit I am getting the error “The published message could not be routed because no subscribers were found.” as shown below. Do you have any idea how I can get rid of it?
Rohit: As this error is stating that “the subscribing orchestration or send port has not been enlisted, or if some of the message properties necessary for subscription evaluation have not been promoted.” Let
What a placethe Gold Coast!!!
Any chance to get back there and this year is looking to be a fantastic 2 day pre-conference
In the training there’ll be no MS speak!! I promise “We’re all in” (washing mouth
out with soap).
First things first – everyone you speak to will pronounce ’Azure’
differently (I once had 3 martial arts instructors all speak their own flavour of
’Korean’ to me).
Now here in Australia we’re standardising (our English-Australian) to Azurey!
Azurey is our official term, which fits alongside ’Timmy’, ’Barbie’ and ’Daveo’
but not Shazza.
What I want to explore with you are all the different options and components that
you could utilise. Having been through several cloud based solutions and building
a cloud based solution over the last 2 years.
So we can use a combination of the available technologies to alleviate some of the
in-house problems (e.g. firewall settings, h/w order and provisioning, server space)
while still maintaining *very* good ownership over it.
One thing is clear right now – with this new landscape the focus has returned to the Developer to
be mindful of what resources they use and HOW they use them.
The price of your solution starts right now from the ground up with the Developer!
(Previously we’ve had limitless memory, disk, cpu, connections, sockets,
select * from customers – developers rarely care)
So the cost model – What do you get charged for?
(short answer – nearly everything)
If you can design a solution with:
1) no use for SQL Azure –as it currently costs a bomb to host a DB.
You could use – SQLCE locally or Azure Storage (Table, Queue, blob) which is cheap
2) limit your Service Bus Connections – both client and server count as a
connection. The connections are averaged out over a day/month and are sampled
every 5 mins, but you certainly don’t want to rack up 100s of connections. A cheaper
alternative is to expose a WCF Endpoint (via a worker role) and have a process communicate
with the Servicebus endpoint handling the requests. This counts for 2 connections
(1 client, 1 server) and is well within the 5 pack.
3) Only data out is charged – not in.
4) Compute VM sizes limit bandwith – across all your compute VMs
e.g. small, there is bandwidth limitations that is enforced whether you have 1 or
10 VMs. Be mindful of that.
5) We can ’monitor’ our cloud machines and even get back perf counters on
each – just to give you that feel good feeling.
Well anyway I must go tweak some F# (best thing I’ve seen in a long whileanother
Here’s the official story @ TechEd – hope to see you there folks!
How “the Cloud” can help you integrate – Microsoft for Developers
With the excitement of technology moving towards “the Cloud” come and learn exactly
what this means to your business and how your development projects can leverage the
Windows Azure Platform without re-architecting your environment. Should you invest
in private cloud, move your application to the public cloud, choose a hybrid approach
or keep the application on-premise?
This two-day development workshop led by renowned Integration Experts provides delegates
with an early opportunity to gain insight and hands-on experience with the Windows
Azure Platform including Windows Azure AppFabric, SQL Azure, Windows Server AppFabric
and BizTalk AppFabric Connect.
This developer workshop focuses on maximising your existing integration technology
investment for an on-premise solution, including architectural design considerations,
real world tips and techniques and hands-on experience with using the integration
tools available today.
Delivered through workshop style presentations and hands-on lab exercises, this technology
focused pre conference training will assist with designing and developing your company
roadmap to the Cloud.

OK, think fast! Name three features of BizTalk that you really love. Now name three that “need some work”. If you have been around BizTalk for more than a few weeks your answers to both of these questions included: “You mean I am limited to three?”, and the two lists likely have some overlap.
If you are reading this, you are interested in knowing what the future of BizTalk is, as am I. It seems that every time Microsoft releases a new technology such as the .NET framework 3.0 (with WF and WCF), Oslo, Dublin, Azure, AppFabric, whatever, the eminent demise of BizTalk is debated. These rumblings have been rolling around once again.
BizTalk isn’t perfect but warts and all it is, in my humble opinion, the best integration option out there. Most of what we know as BizTalk Server today has remained unchanged since BizTalk 2004. Sure there have been some improvements to the interface, and some performance tweaks, and some features have been added, (WCF and EDI support most notably) but the core processing engine has remained untouched.
In no small part I think this is because with an installed base of well over 10,000* customers worldwide Microsoft realizes that the transition to the next BIG version of BizTalk can’t look like the process of upgrading from BizTalk 2002 to 2004. That transition for those of you lucky enough to miss it was more of a wholesale rewrite then a simply upgrade.
The changes that are needed to bring integration into the current decade will be dramatic and will necessarily take some time; maybe even into the next decade if the timeline hinted at by Tony Meleg is anywhere near accurate. In a presentation given at the 2011 Microsoft Worldwide Partner Conference July , 2011, Tony outlined the roadmap for the next few versions of BizTalk and how that is going to play with technologies such as WF, WCF and AppFabric. http://digitalwpc.com/Videos/AllVideos/Permalink/e821e9f8-e379-45b0-8879-12fe271c86be#fbid=VRTVG4xyzMQ
In the presentation Tony identified some customer requests that they are hoping to address over the next few iterations of BizTalk and in the interim with Microsoft’s newest favorite buzzword “AppFabric”. I’ll discuss some of his requests later but for now on to…
My BizTalk Asks
Your list may vary from mine, and I am not going to limit myself to three “needs some improvement” features, but here goes, in no particular order:
Easier control over message box persistence: Since BizTalk always persists every message; it isn’t designed for super-low latency scenarios. Many people have asked for an easy switch to turn off persistence when it isn’t needed, and this happens more often than you might believe. Some competing products have taken a different approach, that is they don’t persist any messages, thus their throughput is much improved. In these systems when persistence is turned on, (frequently requiring additional servers and licenses) their performance positively tanks. This request is not a “simple-fix” since BizTalk at its very core is a publish/subscribe (hub and spoke if you prefer) engine.
Dynamic orchestration filtering: As BizTalk developers we are very aware changing the subscription for an orchestration isn’t a configuration change so much as a coding change. This typically requires versioning considerations, retesting, redeployment, etc. Although a well thought out orchestration design can reduce the frequency of these changes, when changes are necessary the process can be painful. Having a more loosely coupled holistic approach to the end-to-end design, including exposing the orchestration filter as configuration (much as send ports already are) would assist greatly in this area. This has been a long-term request of experienced BizTalk developers.
Support for mirrored databases: Many BizTalk administrators that we work with have asked why mirroring is not supported for the BizTalk databases. This is really more of an issue for the SQL team since that is where the issue originates. SQL server does not support mirroring of transactional databases (though clustering is of course supported). Since most of BizTalk’s core databases communicate with each other transactionally this is a big change and not one that can be implemented by the BizTalk team alone.
ESB like capabilities easier to implement: This is really two requests in one. First it seems that the ESB way of dealing with exceptions really should just become the default. Expecting operations personnel to troubleshoot problems using only the Group Hub and event logs seems rather arcane when compared to the slick web based interface available with the ESB management portal. Second for those companies that desire itinerary processing abilities as available in ESB I’d like a switch that turns that on. Of all the items in the list this one (seemingly) would be the easiest to implement, and may be coming to BizTalk sooner than some of the others.
Ability to change the host used by dynamic send ports: This is a sub-request related to the preceding one. Since the ESB toolkit so heavily leverages dynamic send ports, the ability to change what host they are running on would be really nice. While we are on the topic, how about the ability to dynamically change the pipeline and/or map used by a dynamic port. This feature is effectively offered using the ESB toolkit, but how about making it easier if I don’t want the “whole itinerary thing?”
Callback support for WCF adapters: I’d like to be able to have a client initiate a process via a web service call and then have the process call the client back when it completes. This is certainly supported in WCF itself but at present neither BizTalk’s WCF adapters nor AppFabric supports callbacks.
Microsoft’s BizTalk Asks
In his presentation Tony identified several additional Asks that Microsoft has identified. I don’t doubt that some customers have asked for these features but some of them are going to be big for Microsoft as well.
Low Latency: (already discussed above).
More Flexible Messaging: Tony ignored this point in the presentation so I’m going to say I have addressed it in my Asks above.
Alignment to Windows Workflow: This means different things to different people. Tony identified it as “replace the orchestration engine with the WF engine”. I myself don’t really care whether we call it an orchestration or a workflow what I want is scalability and robustness which at least (so far) we don’t really have in WF. Would it make sense to do this? Sure, having a single engine to maintain makes a lot more sense than two very similar engines but this will not be a trivial change, (Tony identified it as “heart surgery”!)
Put BizTalk on Azure: This seems to have become Microsoft’s solution to almost everything, and who can blame them? Instead of selling you software that you pay for and install once, how much better to sell you software as a service where you get the latest and greatest functionality instantaneously (plus for you) and Microsoft gets to charge you over and over again for it, (plus for Microsoft). That’s what we call a win-win situation? Considering the issues that all cloud providers have experienced over that last few months I think it is going to be a while until companies are going to be fully comfortable outsourcing something as mission critical as integration.
Service Virtualization/Discovery/Tooling: As services become more ubiquitous there is a definite need to enable automatic discovery and integration with these services. Whether the provider and/or consumers are BizTalk this need exists. UDDI held the initial promise for a part of this, while for other parts Microsoft hasn’t really offered a solution. This is one of those things that the BizTalk team likely won’t own, but they have a tight dependency on the eventual solution, whatever it may be.
And I’m going to lump Tony’s last two bullets together: Align Business Rules, and Invest in BAM, improve tooling and make them work across the Microsoft stack: As any of my former students can attest to, I am a huge proponent of using these two features of BizTalk. They are each easy enough to implement if you are using orchestrations, but their abilities go so far beyond that, and I don’t think Microsoft has done a good enough job selling them. For a long time I have seen these as two pieces that could certainly be spun off to stand alone and simply be used by BizTalk as they could be by any other .NET component. As much as I’d hate to see them go, I welcome all developers to use them, so long as we still can!
Any one of these features on its own could; if really fixed to my satisfaction, be quite an effort. Taken as a collection they are going to be very challenging and will necessarily take a long time. The cadence that has been identified is that the changes will come first to the AppFabric space and will be evolutionary, two to three releases per year. I see AppFabric as an incubator where some features will live, some will die, and where change will be frequent. If you are not comfortable with living on the bleeding edge I’d stay clear for now.
BizTalk will continue to be developed and new releases will come every couple of years. The best and the brightest of the AppFabric changes will be integrated a few at a time. If you remember WSE 1.0, 2.0, 3.0 which finally morphed into WCF, the cycle will be similar with AppFabric being the WSE releases and BizTalk being the WCF release.
When I look at BizTalk as a 10 year old product, and considering that the evolution to the eventual BizTalk replacement at least as Tony sees it is being 10 years, I’m feeling pretty good about my decision to stick with BizTalk Server, but I’m also going to keep a weather eye on WF, WCF, and all the AppFabric(s).
For anyone that read this whole thing and watched Tony’s presentation here is my concept of a cloudy thing! Asperatus is a new and upcoming type of cloud. Maybe this should be the code name for the BizTalk in the cloud. It has to be better than v-next right?
*The latest published numbers for customers is from the BizTalk 2009 release and at that time the number was 10,500. With the previous years’ rates of growth this is likely approaching 12,000, but we can only speculate since Microsoft has not released more recent numbers.
I recently started work on upgrading a BizTalk 2006 R2 application to BizTalk 2010. I upgraded the solution to VS 2010, deployed the application to my local BizTalk and verified everything was working.
The next step was to start work on automating the build and deployment process. A perfect opportunity to leverage the TFS and MSBuild […]

After starting off strong for the first part of 2011 with a major site upgrade to BizTalkGurus.com, blogging more frequently, and sending out new editions of The BizTalker, I have really dropped the ball for the past 6 months.
But let me explain. In the past 6 months my life has changed. We had our first baby on 2-9-11. His name is Westin. While a new baby in itself takes a lot of work Westin is very special. A few weeks after birth we noticed Westin just was not eating enough to put on any weight and that is when things started to get more complex.
To summarize what my past 6 months have been like: 29 nights in the hospital (5 separate stays), 11 days in the ICU, 3 MRI’s, 2 surgeries, 12 different doctors covering almost every part of the body, so many x-rays and ultrasounds I have lost count, and countless doctor appointments with as many as 8 in a week. Then Westin was finally diagnosed with a rare genetic disorder called Costello Syndrome. They estimate less than 300 people in the world have this disorder. You can read more about Westin and his life with Costello Syndrome on his blog.
That said, we are hoping the hard part of not knowing what is wrong and not knowing what to expect is over so I am starting to get back into the swing of things. I’ve been back to work for a few months now, traveling again, and life is starting to look a little more normal. I have some upcoming blog posts and even new sample code almost ready and also have some more free BizTalk related books to give away.
Be on the lookout for more to come from me in the near future.
Last week on 4th of August we announced the availability of BizTalk 360 version 2.1. The core update for this release is the alerting/notification capability. Apart from that there are few key issues resolved like clustered host instances handling and ability to start and stop at application level.
Videos seems to be the choice of learning in this modern world. So, we released 6 brand new videos explaining various concepts of Alerting/Notification capabilities.
You can Watch the videos here. We kept the videos as short as possible, in the interest of your time (between 1 and 3 mins).
BizTalk 360 Live Demo
We are also presenting a live demo of BizTalk 360 on 17th August, 3PM GMT. We believe this will give you an opportunity to know all about BizTalk 360 in less than a hour.
