问题 I have been working on a winform app with Oracle 10g database which is using TransactionScope and wanted to modify the maxTimeOut value specified in machine.config file, my machine.config file is in the following location (I am using .net 4 for this app) C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config Originally there was not anything specified for maxTimeOut in it, therefore it defaults to 10 minutes. In order to change it I have added the maxTimeout="00:00:10" value as seen below:

问题 I have hosted my Webapp on server 1 and my database on server 2 But i m getting following error "Communication with the underlying transaction manager has failed." I googled and found a post which mentioned that it is the issue of DTC(Distributed Transaction) I enabled DTC on server2(DB server) and made an exception of it in Firewall. But still same error.

问题 are there any alternative to transactionScope which does not need to enable DTC?? In the transaction I need to make two operations: Create one user (using membership - sql membership provider) Do one insert operation. 回答1: TransactionScope uses the LTM - Lightweight Transaction Manager in .Net.

For MS SQL Server 2008 and

问题 When using ado.net, and creating multiple connections to a MS SQL Server database within a single transaction (using System.Transactions.TransactionScope), does System.Transactions elevate the transaction from the lightweight transaction manager to the distributed transaction coordinator (kernel transaction coordinator on Vista), even if the connection strings are the same for all of the connection objects? The documentation is somewhat ambiguous on this specific situation. It says the
