  • Blog Post: Why and When to use transactions?

    Many people ask - do I need transactions? Why do I need them? When to use them? The answer is simple: use them all the time, unless you have a very good reason not to (for instance, don't use atomic transactions for "long running activities" between businesses). The default should always be yes. You...

  • Blog Post: Transaction.Current and Ambient Transactions

    Ambient transactions are defined as transactions that live in the current thread or object context that anybody interested can query for their existence and use them to do work as part of them. Their existence means that the user wants to do a series of actions in a transacted "all or nothing" way. They...
  • Blog Post: XA Transactions in Windows XP SP2

    Service Pack 2 adds to Windows XP the same level of security as in Windows Server 2003 for XA transactions (transactions that are used with XA-compliant resource managers like Oracle, IBM DB/2 etc).

  • Blog Post: Using distributed transactions in .Net 1.x without deriving from ServicedComponent

    The most used feature of System.EnterpriseServices or COM+ is the distributed transaction support.

  • Blog Post: What is MSDTC and why do I need to care about it?

    I've been talking for a while about MSDTC and transactions without explaining them. I know many of you reading this blog already know the terms, but some of the developers just entering the enterprise space don't know if they should care or not about these subjects. MSDTC is an acronym for Microsoft...

  • Blog Post: Isolation Levels

    MSDTC , COM+ or EnterpriseServices are allowing you to specify an isolation level for transactions so that you can increase concurrency to improve performance and scalability. But, the value you set for the isolation level is used by MSDTC only to pass it to the resource manager(s), more like a hint...

    When you install Windows Server 2003, most of the services will be off by default, including MSDTC network access.
