Mirroring :: Email Deadlock Information When A Deadlock Occurs
Nov 10, 2015
Is there a way to send out an email woth deadlock information (victim query, winner query, process id's and resources on which the deadlock occurred) as soon as a deadlock occurs in a database or at instance level?I currently has trace flag 1222 turned on. And also created an alert that send me an email whenever a deadlock occurs. but it just says that a deadlock occurred and I log into sql server error log and review the information.

Hi,
I am facing this problem with SQL Server 2000 as well as with SQL Server 2005. I want to get notified when a deadlock occurs. This is what I have done.
I have setup an SQL Server Agent alert for the error number 1205. The alert is enabled and in response to the alert I am invoking a job and also tried email and net send etc.
Now I simulated deadlock situation by using two connections and received the 1205 error. However when I go back to the alert and see it does not invoke the job nor send message nor email. I find the number of occurrances of the alert as 0 which means that the alert never occurred. Why am I not able to trap the 1205 error message and get a notification?
I understand that I can enable trace flag 1204 and trace flag 3605 to get the deadlock event and the complete description logged to the sql server error log. But my question is why am I not able to use the 1205 event in the sql server agent alert. Even if I enable 1204 and 3605 I am only able to get the information of the deadlock in the error log but the alert is not getting triggered.
I am able to get all other alerts except the alert for 1205 and in general for any severity 13 alerts they are not getting triggered.
Any help is appreciated. I got this problem with sql server 2000 sp4 and sql server 2005 sp1.
Regards,
Ravi

I cannot even easily find out what process blockswhat. Does anyone have any experience with these. ANy and all help willbe appreaciated.

I have enabled 1222 and 1204 trace and restarted sql server. then i have replicated deadlock in my local.
This is the error came in sql
Msg 1205, Level 13, State 45, Line 1
Transaction (Process ID 51) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
Then i opened ERRORLOG file , there is no information about deadlocks .
Where can found deadlock information and file path. is there any extra options required to enable trace?

We have (running SQL 2012 Std) and have enabled trace flag 1204 and 1222 for capturing deadlock through extended events. I have enabled deadlock notification through email .But it only send deadlock event occurred notification from the sql server error log . I was wondering if its possible to email the deadlock details they get generated in extended events via DB mail.

Hello everyone,Can you please help me on the following problem that i have.I am using the microsoft web stress tools to simulate 100 concurrent users for one min, and the database will go into a deadlock for large part of the 100 concurrent users.Please help...i've been stuck for many days already. Thanks...Error 5: Transaction (Process ID 497) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction..Here is my code.My connection string:<connectionStrings><add name="Connection_String" connectionString="Data Source=123.123.123.123;Initial Catalog=DBName;MultipleActiveResultSets=true;User ID=uname;Password=upass;connection timeout=60" providerName="System.Data.SqlClient"/> </connectionStrings>My web apps will call the below function. And the deadlock always occurs at the update statement (error 5). I believe it's probably the select statement above locked up the row. I've put in (UPDLOCK) for the select statement, and it still didn't work.private void UpdateLogTables(string Station_ID, string ContentFileName, string FileSize, string IP){ContentFileName = Regex.Replace(ContentFileName, "'", "''");string AdFileName = "";string AdFileNameClause = "";string DownloadCount = "";string TotalFileSize = "";string DownloadDate = "";string currentDate = "";string tempDate = "";string MyString = "";SqlConnection MyConnection = new SqlConnection(System.Configuration.ConfigurationMa nager.ConnectionStrings["Connection_String"].ConnectionString);SqlCommand myCommand = null;SqlDataReader myReader = null;try{MyConnection.Open();MyString = "SELECT AdFileName FROM tblContentRef WHERE Station_ID = '" + Station_ID + "' AND ContentFileName = '" + ContentFileName + "'";myCommand = new SqlCommand(MyString, MyConnection);myCommand.CommandTimeout = 60;myReader = myCommand.ExecuteReader();if (myReader.Read()) {AdFileName = myReader["AdFileName"].ToString();} }catch (Exception e){Response.Write("Error 2: " + e.Message + ".<br><br>Please email abc@abc.com.<br><br>Thank you.");} finally{if (myReader != null){myReader.Close();}}if (AdFileName != ""){AdFileName = "'" + AdFileName.Replace("'", "''") + "'";AdFileNameClause = "AdFileName = " + AdFileName;}else{AdFileName = "NULL";AdFileNameClause = "AdFileName IS NULL";}InsertDetailsLogTable(Station_ID, ContentFileName, AdFileName, FileSize, IP, MyConnection);SqlDataReader myReader2 = null;SqlCommand myCommand2 = null;bool Readable = false;try{MyString = "SELECT DownloadCount, TotalFileSize, DownloadDate FROM tblSummaryLog (UPDLOCK) WHERE Station_ID = '" + Station_ID + "' AND ContentFileName = '" + ContentFileName + "' AND " + AdFileNameClause + " ORDER BY DownloadDate DESC";myCommand2 = new SqlCommand(MyString, MyConnection);myCommand2.CommandTimeout = 60;myReader2 = myCommand2.ExecuteReader();if (myReader2.Read()){DownloadCount = myReader2["DownloadCount"].ToString();TotalFileSize = myReader2["TotalFileSize"].ToString();DownloadDate = myReader2["DownloadDate"].ToString();currentDate = DateTime.Now.ToString("M/d/yyyy");string[] inDate = DownloadDate.Split(new char[] { ' ' });tempDate = inDate[0];Readable = true;}if (myReader2 != null){myReader2.Close();} if (Readable){if (tempDate == currentDate){DownloadCount = Convert.ToString(Convert.ToInt32(DownloadCount) + 1);TotalFileSize = Convert.ToString(Convert.ToInt32(TotalFileSize) + Convert.ToInt32(FileSize));UpdateSummaryLogTable(DownloadCount, TotalFileSize, Station_ID, ContentFileName, AdFileNameClause, DownloadDate, MyConnection);}else{InsertSummaryLogTable(Station_ID, ContentFileName, AdFileName, FileSize, MyConnection);}}else{InsertSummaryLogTable(Station_ID, ContentFileName, AdFileName, FileSize, MyConnection);} }catch (Exception e){Response.Write("Error 3: " + e.Message + ".<br><br>Please email abc@abc.com.<br><br>Thank you.");}finally{ if (MyConnection != null){ MyConnection.Close();} }}private void InsertDetailsLogTable(string Station_ID, string ContentFileName, string AdFileName, string FileSize, string IP, SqlConnection MyConnection){string MyString = @"INSERT INTO tblDetailsLog ( Station_ID, ContentFileName, AdFileName, FileSize, IP, DateTime ) VALUES ( '" + Station_ID + "', '" + ContentFileName + "', " + AdFileName + ", '" + FileSize + "', '" + IP + "', getdate() )";try{ SqlCommand MyCmd = new SqlCommand(MyString, MyConnection);MyCmd.CommandTimeout = 60;MyCmd.ExecuteNonQuery();

In a high traffic environment, deadlocks eventually occur as number of data processes increase. How can deadlocks be avoided, minimized and resolved. Please kindly provide scenario examples and samples of T-SQL code. Thanks much.

SQL 7.0
Hi All
Iam trying to bcp a table(residing on my prod server to my local machine from command prompt) .Actually the table iam trying to bcp has heavy updates and selects, from users (70 users).
The users complain that system becomes slow.Is it got anything to do with my trying to bcp the mentioned table(table has 170,000 records).Also whenever i try to bcp this table, only after being chosen as the deadlock victim by Sql server,for 3 or 4 times that iam able to bcp the table.
Any help regarding this will be very much appreciated
TIA

I am unable to control the granularity of locks in our queries.
We are running queries through MTS and are getting deadlocks.
The batch includes two inserts and one select query - all are hitting on
only one table. This table has a unique clustered and a unique nonclustered index as well
as a primary key.
Within the batch, I have given a table hint to set transaction isolation level
to READCOMMITTED, ROWLOCK for the insert statements, like this
INSERT INTO ib_price with (READCOMMITTED,ROWLOCK)........
and the same for the Select statement.
SELECT retail_price, price_status_id FROM ib_price with (READCOMMITTED,ROWLOCK)
When I run sp_lock on the spid, I get output indicating that
SS7 is placing a IX lock on the table. I'm pretty sure this is
a big contributor to the deadlock.
I get the deadlock when I try to run more than one client with similar insert parameters.
How can I control the granularity to just rowlocks?
All help is appreciated.
Thanks
Brett

Hi,
I am getting deadlock running a stored procedure from two machines. Looking at the error log (generated using trace flag 1204 and 3605), it seems the deadlock is on a key. But what I fail to understand is how come sql server granted exclusive lock on the key to both connections. The grant list shows that lock with Mode X is granted to both connection.

Can anyone help me resolve deadlock with following text
Parallel Query worker thread Involved in deadlock.
I am particularly interested in resolving details of above mentioned line,as I started getting dead lock
more frequently now and when I look
into query involved blocking and victim
I see nothing that can cause deadlock
they are update insert and select statement which were fine for long and all of sudden started giving problem.
Thanks in advance,
for any knowledge share

Hi,
When many users run some stored procedures I 've got some deadlocks. How to avoid that?
We run large stored procedures code which are using sometime the same table.
What is the best way for using the transaction isolation level, fillfactor indexes, procedure cache configuration ...etc to avoid that.
In addition, I am using MTS and sometimes the Tempdb is also locked, is it a Microsoft bug (again) ?

Hi
Sorry for bombading the forum with all these questions, but i am relatively new to sql 2000.
I am getting dead lock on the following procedure.
important background information
1. this is a multi user web-based call centre application
2. this procedure loads up a new contact based on priority
I see no reason how a dead lock could occur.
does any one have any idea. could it be something else that is locking up resource used by this procedure?
CREATE PROCEDURE topcat.getNewContactInfo
(
@contact_id int
)
AS
BEGIN
begin transaction
declare @id int
set @id = (SELECT TOP 1 _id FROM class_contact WHERE (status IS NULL OR status='New Contact' OR status = 'No Connect' OR status='callback') AND (checked_in IS NULL OR checked_in <> 1) AND (callback_date >= (getdate() + 1) OR callback_date IS NULL ) ORDER BY priority DESC)
UPDATE class_contact SET checked_in = 1 WHERE _id = @id
SELECT TOP 1 * FROM class_contact
WHERE _id = @id
commit
END
GO
wat i dont' get is that, this procedure only has one update statement, this is the only statement that could possibly hold a lock on another resource (i think) , i can't see how a dead lock can happen in this case since this procedure doesn't hold up 2 resources at a time.

Using SQL Server 2000 SP3a, I run the following in 2 query analizerwindows on the Northwind database, the second one always gets thedeadlock Msg 1205:Window 1:declare @cnt intselect @cnt = 5while @cnt > 0beginbegin transactionselect * from orders (updlock) where employeeid = 1update orders set employeeid = 1 where employeeid = 1waitfor delay '00:00:03'commitselect @cnt = @cnt -1endWindow 2:declare @cnt intselect @cnt = 5while @cnt > 0beginbegin transactionselect * from orders (updlock) where employeeid = 1 and customerid ='ERNSH'waitfor delay '00:00:02'commitselect @cnt = @cnt -1endThe query in the first window gets 123 rows and places update locks onthem, then updates them and commits. The query in the second windowgets a subset (about 5) of the results that window 1 gets also tryingto place update locks on the same rows. Shouldn't the query in window 2just wait for the transaction in window 1 to finish? why would itdeadlock?you can also get rid of the delay in the second window and it willdeadlock faster.thanks in advance.Eugene

I have a table that every 30 minutes needs to be repopulated fromanother table that is recreated from scratch just before.What I did was this:CREATE PROCEDURE BatchUpdProducts ASbegin transactiondelete productsinsert into productsselect * from productsTempcommit transactionGOThis takes about 30 seconds to run. I tried it doing it with a cursor,row by row, but it took like 30 minutes to run instead. The problemis with the fast approach is, once in a while I get a deadlock errorin different areas trying to access the products table. Using SQLServer 2000 by the way.Any ideas?

I have set up an alert to detect when Page Deadlocks rise above 0. Overnight I have DTS packages populating SQL Server and various other jobs (Cognos Cube Builds etc.). My alert detected a Deadlock during the night but all of my processes completed fine. My problem/misunderstanding is that my alert is still popping up every 5 mins saying there is a Deadlock yet there is nothing running or no-one accessing SQL server and I cannot see any trace of the Deadlock in the Current Activity. Is this normal or is it a bug?

I have (amongst many) an overnight SQL stored procedure that occasionally takes over an hour to run compared to its usual 2 minutes. It does the same each night, as does everything around it. (N.B. The job truncates and reinserts data into a table.)
I'm just wondering if a user request during the day that reads the table perhaps leave the PID open and thus a lock open with it. Then, perhaps my SQL job comes along and waits for the lock to release before it performs the truncate.
Couple of questions:
1. Could this happen?
2. If so, is there a log anywhere to suggest that a deadlock situation arose and PID x was the loser?
Thx in advance.

Hi guys;
i use a transaction that takes a long time to execute.(Different updates on different tables)
I want to use in my transaction a TABLOCKX after each update in order to Lock the table within the Transaction (Until the transaction will finish).
This will normaly force another transaction using the same tables within the first transaction to wait until the lock will release.
1- Because there is no time out set . Does the second transaction wait until the first transaction be commited even if it takes more long time.
2- Does such situation hold a deadlock.
i will apreciate your help. Thinks

I've been diagnosing deadlocks for a last couple weeks at a client site and I understand the KEY: and TAB: locks issues. However, the client recently experienced a series of multi-branch deadlocks for which I can find no information. Attached is the deadlock text from the ERRORLOG. Any help would be much appreciated.
