transactionscope

When i create a TransactionScope object as followed: using (TransactionScope ts = new TransactionScope()) { // Do stuff... } What is the default transaction timeout of the given ts object? According to David Browne it is 1 minute TransactionScope’s default constructor defaults the isolation level to Serializable and the timeout to 1 minute using new TransactionScope() Considered Harmful 来源： https://stackoverflow.com/questions/20224748/what-is-transactionscope-default-timeout-value

Just curious if anyone else has got this particular error and know how to solve it? The scenario is as follow... We have an ASP.NET web application using Enterprise Library running on Windows Server 2008 IIS farm connecting to a SQL Server 2008 cluster back end. MSDTC is turned on. DB connections are pooled. My suspicion is that somewhere along the line there is a failed MSDTC transaction, the connection got returned to the pool and the next query on a different page is picking up the misbehaving connection and got this particular error. Funny thing is we got this error on a query that has no

I'm occasionaly getting this exception on our production server: System.ArgumentNullException: Value cannot be null. at System.Threading.Monitor.Enter(Object obj) at System.Data.ProviderBase.DbConnectionPool.TransactedConnectionPool.TransactionEnded(Transaction transaction, DbConnectionInternal transactedObject) at System.Data.SqlClient.SqlDelegatedTransaction.SinglePhaseCommit(SinglePhaseEnlistment enlistment) at System.Transactions.TransactionStateDelegatedCommitting.EnterState(InternalTransaction tx) at System.Transactions.CommittableTransaction.Commit() at System.Transactions

Forgive me I am not good at EF6. If I make some mistake . Please help me to correct it. Thanks. Firstly I want to implement the business logic in my service layer like below. public class userService { void createWithCommit(User user) { MyEntityContext db= new MyEntityContext (); ... db.Users.add(user);//Add a new user entity .... Work w = new Work(); ... db.Works.add(w);//Add a new work entity db.savechanges();//commit the changes which will insert 2 new record . one is user . another is work. } } But in some service class I want to call multiple others service method in one transaction like

We are having a few problems understanding how best to use NHibernate. We typically have a relatively large number of quite small (in terms of number of tables) SQL Server databases rather than one database with a lot of objects. We are looking at various options for handling multiple session factories and probably have this under control. However we are not sure how we would wrap all calls in a single transaction. Using hand-rolled data access you would just wrap it all in a TransactionScope but we are a little reluctant to do this with NHibernate as it seems to like to handle all its own

I'm looking for a solution to a design problem. This will take a bit of explaining. I would post code, but that woul make this even longer. I have a custom generic collection I use to hold Business Objects as needed. For easy of reference, call the business objects BO and the generic collection GC . Inside GC I have a private collection of those business objects that have been flagged for deletion. Call this private collection PDC . I can have an arbitrary number of GC's, each with their own PDC, at any one time, plus other BOs that aren't in any collection. When I save changes I loop over all

I've been trying to use TransactionScope with a DB2 database (using DB2 .Net provider v 9.0.0.2 and c# 2.0) which SHOULD be supported according to IBM. I have tried all the advice i could find on the IBM forums (such as here ) to no avail. I have enabled XA transactions on my XP Sp2 machine, tried also from a Win 2003 Server machine but i consistently get the infamous error: ERROR [58005] [IBM][DB2/NT] SQL0998N Error occurred during transaction or heuristic processing. Reason Code = "16". Subcode = "2-80004005". SQLSTATE=58005 The windows event log says: The XA Transaction Manager attempted to
