I was reading today a great blog entry by the immensely knowledgeable Richard Seroter about debatching inbound messages from biztalk wcf-sql adapter and was inspired to write some of my own musings on this great new adapter. Today will be transaction scopes.   The WCF SQL adapter allows you to choose to use the "Ambient" transaction or a different one when communicating with the Message Box. This means the adapter can enlist its communication with the Message Box (i.e. submission to BizTalk) in the same DTC as the read from the SQL database where the receive is happening. The great feature with that is if you go "ambient" and you have no subscriptions set up in BizTalk the records stay in the source database instead of being pulled and simply suspended in BizTalk (the other option). This can be a life saver because a source system may think the records have gone... (more)

Why UDDI Is Important

I am writing for cio.com again and thought I'd go back down the SOA track. This will be in parallel to my BizTalk specific posts here, but there will be a lot of overlap. The UDDI series I am just starting will mostly be based on the UDDI v3 that is part of BizTalk Server 2009. The first of the cio.com articles can be found here: http://advice.cio.com/dan_rosanova/why_uddi_is_important Future articles will elaborate on the points presented in the article above. ... (more)

Zen in Orchestration Design

I have been writing a lot for my upcoming BizTalk book and after locking myself away in my office I often turn to The Modern Japanese Garden to relax. Besides being a refreshing reminder why digital books will never have the place in my life that physical books do (the images are amazing), the book helps me relax my mind and focus my thoughts. I've always appreciated Japanese design aesthetic, but it was not until learning more about Japanese gardening in particular I began to appreciate why. A quote from the book above reads: "As in sumi painting, we should remove, not add, and... (more)

What’s in a Namespace

SOA & WOA Magazine on Ulitzer Although XML has been around for quite some time many developers still don't know too much about it. Not needing to know too much about it is one of XML's strengths, but cursory knowledge is rapidly becoming mandatory for all developers. This post will discuss some of the details of namespaces in XML. In XML a namespace is just that, a space (or area) identified by a name. When we look at a namespace such as http://novaenterprisesystems.com/schemas/purchaseorder we are not actually identifying a location on the web. Granted it does look like a URL an... (more)

Going Global – BizTalk in Global Deployments

I was recently approached by a client about what options they had for configuring BizTalk across their global enterprise. They really wanted to avoid idle servers and spread their processing load over their global enterprise as much as possible. They also wanted to have failover capabilities in case they lost their primary datacenter. I thought a lot about this and had some ideas, but it was immediately clear to me that ultimately SQL Server is the critical point of failure in a BizTalk deployment. I've used a few approaches in the past to address this, such as the typical Log S... (more)
