SQL Server :: Deadlocked Transaction On Lock Resources
Sep 24, 2010I develop an application using LINQ to SQL. Recently I deploy the application on server and starts performance testing using WAPT for 100 users. Unfortunately, 90 requests are failed while placing an order and only 10 are passed. I analyse and found that for every failed request I got an error "System Exception: Transaction (Process Id 68) was Deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction."

Oct 21, 2010I have a deadlock problem that occurs every 5 minutes on SQL update. I get the following error randomly - means qurey failed one time every 200 calls. I'm using transaction scope to manage transaction.
code:
using(TransactionScope scope =
new
TransactionScope())
{
SELECT ... FROM TABLE1
UPDATE TABLE1 SET [F1] = @F1, [F2] = @F2, [F3] = @F3, [F4] = @F4, [F5] = @F5 WHERE UId = @UId
scope.Complete();
}
error:

SQL Server :: Error "Transaction (Process ID) Was Deadlocked On Lock Resources With Another Process And Has Been Chosen"
Jul 23, 2010I have a stored procedure which fetches data after joining 8-9 tables and inserts that into a temp table. It was running fine till now, but now when the amount of data fetched have exceeded 20000, the SP is breaking. I have debugged the sp and found that this main query is failing after returning arround 15000-16000 records.
The error message says Transaction (Process ID) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction. I know what is deadlock, but when i checked with SP_LOCK stored proc i only found that my process is running on database only. So how is this getting deadlocked when there are no other processes running simultaneously on server.
Transaction Deadlocked On Lock Communication Buffer Resources With Another Process

What I find is that I will keep getting these error message as posted in the subject... It will work for some but others I get this message. Thoughts on how to avoid that, or is that just something I'll need to work around with timing?

View 3 RepliesFlush 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

How To Lock Down & Secure Files Stored On Server In .NET
Apr 23, 2010How do I go about securing files that are stored on the server? We have an ASP.NET app which generates PDFs. These are not stored in the wwwroot folder but in another folder i.e. C:inetpubdata. This provides more security but maybe not enough. The ASP.NET/IIS process will need write access to this folder so it generate the PDFs there.
Once the pdf is generated, it can be viewed using an ASP.NET form called viewpdf.aspx with the file to be viewed add to the query string like so viewpdf.aspx?FILE=mynewfile.pdf. This is loaded from a gridview.
The full path to C:inetpubdata is resolved and loaded in the Page_load event of the viewer page. Now I'm wondering how to secure this. Anybody could just view the file. Not by entering in the URL, as it won't been seen by IIS (its not in wwwroot), but could change the querystring in the viewpdf page.
How do I stop anybody hacking this?

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?

I need to have a server log that will help to determine the number of items entered into the db and where those items are entered, without having query each table. It should be able to give me the average monthly volume of items input in SQL.
Can this be done using Sql Triggers or any other alternative?
I have to make sure that if I use trigger as the alternative I should have only one table to be updated with all the details of the Updates/Inserts being inserted into the Trigger table after the insertion into the original table.
Below given are some of the create table statements that I have for which I need to have a server log of the updates & inserts.
