In Summary, there are two types of transactions:
Atomic transactions, which take short time to execute (typically seconds). These transactions satisfy all ACID attributes, and thus need to acquire data locks on resource managers such as SQL Server. If all operations within a transaction scope succeed, then the transactions is committed automatically, else if any operation fails the entire transaction is rolled back. This is done via a transaction manager such as DTC.
Integrated systems have to deal with tough challenges when it comes to secure messaging. If system A is sending a message to system B, this requires the implementation of important security measures. These can be summarized by:
Secure messaging is achieved using public and private keys. These are numerical values that are mathematically linked. An organization generates these keys, it keeps the private key as its own secret, and distributes the public key to any organization that wants to do exchange secure messages. Because these keys are mathematically linked, data encrypted with the public key can only be decrypted by the private key.
I’m in the midst of a BizTalk project where we’re load testing our solution. Our receive adapters are WCF-based and therefore tuning WCF is a critical aspect of the overall solution performance. I have gone through the same tuning times before in every WCF project. But I always was lazy documenting the information and ended up looking up the bits and pieces time and time again to refresh my memory. Now I decided to document this information in a post for myself and others.
However, I will not simply write the keys to adjust and leave it there. I will explain the reason we adjust these keys and what they really mean. So bear with me and follow along.
This post is for two sets of readers: those who are new to Microsoft Business Rule Engine and are looking for a direct hands-on approach rather than going though the theory and architecture behind BRE (links for that at the Additional Resources section), and those who are familiar (but not experts) with the topic in general, and are looking to understand, in a practical manner, how to program with BRE and leverage some of its powerful offerings.

When designing a BizTalk solution that involves WCF (which is most of the times), you need to carefully consider the exception handling mechanism. This requires understanding for both BizTalk Exception handling as well as WCF (and SOAF) faults.
This post explains the mechanisms to implement exception handling when you have a BizTalk process that both calls WCF services and when the process itself is exposed as a WCF service. Continue reading
A BizTalk message is any binary stream of data. It can be an XML Document, flat-file, .NET serialized class, or any other binary stream of data such as zip or pdf.
A BizTalk Message is represented by two different objects, depending on which part of BizTalk its being processed.
