Flush Separate Castle ActiveRecord Transaction And Refresh Object In Another Transaction
Jun 15, 2010I've got all of my ASP.NET requests wrapped in a Session and a Transaction that gets commited only at the very end of the request. At some point during execution of the request, I would like to insert an object and make it visible to other potential threads - i.e. split the insertion into a new transaction, commit that transaction, and move on. The reason is that the request in question hits an API that then chain hits another one of my pages (near-synchronously) to let me know that it processed, and thus double submits a transaction record, because the original request had not yet finished, and thus not committed the transaction record.
So I've tried wrapping the insertion code with a new SessionScope, TransactionScope(TransactionMode.New), combination of both, flushing everything manually, etc. However, when I call Refresh on the object I'm still getting the old object state. Here's some code sample for what I'm seeing:
Post outsidePost = Post.Find(id); // status of this post is Status.Old
using (TransactionScope transaction = new TransactionScope(TransactionMode.New))
{
Post p = Post.Find(id);
p.Status = Status.New; // new status set here
p.Update();
SessionScope.Current.Flush();
transaction.Flush();
transaction.VoteCommit();
}
outsidePost.Refresh();
// refresh doesn't get the new status, status is still Status.Old

Dec 9, 2010I was thinking of formatting it like this
TYYYYMMDDNNNNNNNNNNX

Where
T is type
YYYY is year

N is sequencial number
X is check digit
The problem is, how do I generate the sequencial number? since my primary key is not an auto increment integer value, if it was i would use that, but its not.
EDIT can I have the sequencial number resets itself after 1 day (24hours).

NHibernate Transaction Management In .NET MVC ?
Apr 5, 2010I am writing a simple ASP.NET MVC using session per request and transaction per request patterns (custom HttpModule).It seems to work properly, but.. the performance is terrible (a simple page loads ~7 seconds). For every http request, graphical resources incuding (all images on the site) a transaction is created and that seems to delay the loading times (without the transactions loading times per one image are ~1-10 ms with transactions they are over 1 second).What is the proper way to manage transactions in ASP.NET MVC + NH stack?
When i've put all transactions into my repository methods, for some obscure reasons I got 'implicit transactions' warning in NHProf (the SQL statements were executed outside transaction, even that in code session.Save()/Update()/etc methods were invoked within transaction 'using' scope and before transaction.Commit() call) BTW are implicit transactions really bad?
ADO.NET :: Transaction Is Not Working Using SqlTransaction Class?
Sep 23, 2010Here is my code:
[Code]....
The problem is that the transaction is not working.For instance,now the code is correct so both sql statements are getting executed.However,yesterday the 'update' statement was incorrect but I could not realise that IT WAS NOT ALRIGHT, because the function was not throwing myTrans.Rollback().I had put a breakpoint and there was no rollback.Apparently, now the sql statements,above,are ok,so there is no issue at the moment,however if there was an error,still the function would execute as if the sql statements were successful.
I know that I can use a Stored procedure and finish with it.But i want to see it how the Transaction works using SQLtransaction class.
DataSource Controls :: Transaction Is Not Getting Rollback?
Mar 15, 2010I have written several queries under one single transaction. When any of the query throws an error then the whole transaction should rollback. However, in some rare cases say 2% cases even after the error the next transaction is getting comitted.
note that all transaction processes (opening, committing and rollback) is done through .net.

SQL Server :: Any Alternatives Of Using Transaction Scope
Jan 24, 2011I have a multiple database operation, Have three tables (MSsql) and need to delete one row in each table in one operation, one after another. (Three functions, three rows of code). Everything is working as it should be, recently I was advised to use a transaction scope, which should guarantee the safety of deletion from all 3 tables together.
Here is my new code:
[Code]....
Locally all worked just fine, the transaction scope worked well, but when I have uploaded my application to my hosting server, I got an error of: The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025).I talked with the host support, they tried to do something, then I got this error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).
After a 2 days, They have contacted me, they said it is not possible to disable some restriction, that will allow an access to this operation, because I'm using shared hosting, and I need to upgrade my plan to VPS. VPS is a very expensive for me, and I can't afford it, What I'm looking is a some similar way of doing the same operation as transaction scope do, that may work at my hosting, At least I would like to try something else. Is there any additional way for the transaction scope?

View 1 RepliesHow To Make A Bulk Transaction Entirely Asynchronous
Aug 13, 2010i'm dealing with an ASP.NET 4.0 Web Forms Application in which the DAL is built with a combination of LINQ-SQL and classic ADO.NET (for auditing transactions, and bulk updates).
I have an admin page on the site which performs an update on a bunch of records (could be thousands), and not to mention there is T-SQL triggers in place on those records. Needless to say, its a killer of an update.
So of course, the page is timing out. The update transaction is performing with the following code:
db.ExecuteCommand("UPDATE [tblFoo] SET [IsFoo] = 0 WHERE [Bar] = {0}", bar.Id);
So it's a classic ADO.NET bulk update.
What i've tried to do is make the call to this method asynchronous, by firing off a thread on the button click on the form:
[code]...
The method OnMyAsyncMethod simply executes the above ADO.NET call.
This solved the UI problem, being the page now posts back and refreshes immediately. But then around 30 seconds lateri see that wonderful little flashing light on my Visual Studio toolbar - "an unhandled exception has occured, would you like to attach to process, etc".
So of course, now the actual call in the DAL is timing out.
Am i doing this wrong - is there a way i can perform the update transaction (db.ExecuteCommand) totally asynchrously?
Hopefully you see what im trying to do - i just need to fire off a killer of a T-SQL transaction. The only thing i need back from the call is the number of rows updated.
ADO.NET :: Transaction (Process ID 51) Deadlocked On Lock

WCF / ASMX :: Multiple Web Methods In One Transaction?
Aug 20, 2010it may sound a bit newbish question.We have a web service that comunicates with the database and exposes web methods that enables the application to access the database. Each method does only one operation (Insert, Update or Delete). What I need to do is create a transaction that will be consisted of multiple calls to the database, meaning multiple calls of more then one web methods. Can I do that? (I read that if the web method does not throw exception - or ContextUtil.SetAbort() is not called - the transaction will be commited automatically when the web method finishes executing, which I don't want to happen because I want to call another web method in the same transaction, and then manually commit the transaction)
