If you do distributed transactions across the network, you know about Allow Inbound and Allow Outbound security settings for DTC (available by running dcomcnfg or by opening Component Services). The help describes these settings as: Allow Inbound...

Clemens Vasters gives a great introduction to Microsoft Azure .Net Service Bus and its 4 feature areas: Naming, Registry, Connectivity, and Eventing. Find it at http://vasters.com/clemensv/PermaLink,guid,92d78bee-2cfd-4a29-95ab-c5abb9b905e7.aspx

I use remote desktop daily. The Atbroker.exe application error followed by black screen seemed to be gone for a while. Now it is back. The only solution that I know of and which works most of the times is "CTRL-ALT-END" (the equivalent of “CTRL-ALT-DEL...

Transactions are great when everyone plays in. You group a set of activities together under a transaction and you start executing them. If anything bad happens along the way or something doesn't go as planned, invoke rollback and all is taking care of...

To access the MSDTC and COM+ configuration tool in Windows Vista, also known as Component Services MMC, you have the following options: 1. Run “dcomcnfg” 2. Or run: %SystemRoot%\System32\comexp.msc 3. Or if you prefer, you can add a shortcut...

The design guidelines for exception handling are quite clear on avoiding “catch all” and/or avoiding catching exceptions you can’t handle. But there are cases when you really need to know if the try block completed successfully or not, and possibly take...

I like using the command prompt for a lot of things and working with long (or very long) path names is something that is common these days. Fortunately, you can customize cmd by using "prompt". Do a “prompt /?” in a command window to see all the options...

The Bug I call it a bug. Initially I was persuaded to believe it was a feature; later I was "convinced" that it is now a matter of app compat and it can't be changed anymore. Let’s look at the following code: SqlConnection connection1 ...

If you read the documentation for TransactionScope , you will find: "If no exception occurs within the transaction scope […], then the transaction in which the scope participates is allowed to proceed. If an exception does occur within the transaction...

Great news! The new updates added to System.Data and SQL Server 2008 finally allow multiple Open/Close connections to the same SQL Server without promoting the transaction to MSDTC. This was by far the most requested feature for the System.Transactions...

In .Net 3.5 I can write a transactional code block as follows: transacted(()=> { using (SqlConnection connection = new SqlConnection(connectionString)) { connection.Open(); SqlCommand command1 = new SqlCommand(commandString1, connection...

System.Transactions transactions are bounded to the appdomain. Which means that if you make in-appdomain calls from inside a TransactionScope, those calls will share the transaction. This also means that if you need to make a call outside the current...

TIP is getting deprecated - see the note at http://msdn2.microsoft.com/en-us/library/ms679484(VS.85).aspx If the native OleTx protocol used by MSDTC and System.Transactions is not friendly enough for your firewall, you should consider the WS-AtomicTransactions...

These days I'm in Romania with a tour at 3 universities (in Bucharest, Cluj and Iasi) talking about Windows Communication Foundation, distributed systems and web services. Adi Oltean is also talking about storage technologies in Windows. So far the...

In the "Orcas" March 2007 CTP for Visual Studio and .Net , Windows Communication Foundation brings support for OASIS specifications WS-AtomicTransaction 1.1 and WS-Coordination 1.1 . WCF will have side-by-side support with the 1.0 versions of these specs...

Supporting transactions is part of your component contract. If you shipped a component yesterday that exposed MyComp.DoWork to the public, and today you want to add transactional support to your component, you shouldn't use the same method MyComp.DoWork...

If you are providing support for promotable transactions for your resource manager using PSPE then you need to remember to "support" Phase 0. In general, a resource manager doesn't need to do anything special about Phase 0; this phase will be handled...

We already know the benefits of promotable transactions. They are all about performance, being very fast and lightweight. But then you get into situations where you know for sure that you are going to talk to a second resource manager, so you know...

I'm getting way too much spam these days. I wanted to keep the comments open for ever so I can get your feedback at any time you wanted to send it to me. Unfortunately spam is consuming my time so I decided to limit the lifetime for comments to 90 days...

In a previous post ( http://blogs.msdn.com/florinlazar/archive/2006/01/29/518956.aspx ) I talked about Phase0 and some useful things it allows you to do. Although not referred as Phase0, phase 0 features are available in .Net System.Transactions in two...

I'm really happy to announce that our own forum, dedicated to transactions in Windows and .Net is now live at http://forums.microsoft.com/MSDN/ShowForum.aspx?ForumID=388&SiteID=1 The RSS feed for the forum is http://forums.microsoft.com/MSDN/rss...

In an effort to have a common place for all the transactions technologies we provide (and we started to have a good number of technologies that continues to grow), we have put together a webpage on Microsoft.com dedicated to transactions. The address...

The most known technique of implementing distributed transaction is the "two-phase commit" (2PC). Here is a quick summary of how this technique works: - Active phase: After the transaction is created and before the "commit" message is issued by the creator...
