The errormessage after a deadlock gives very little information: "Your transaction (process ID #12) was deadlocked with another process and has been chosen as the deadlock victim. Rerun your transaction."
But what resources, ie tables, indexes etc, are really deadlocked?
Is it possible to set a switch or something to log all relevant information about a deadlock for later investigation?
Hi,
I was trying to extract data from the source server using OLEDB Source and SQL Server Destination when i encountered this error:
"Transaction (Process ID 135) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.".
What must be done so that even if the table being queried is locked, i wouldn't experience any deadlock?

Hi, i am getting this error when i am running a stored procedure.
Transaction (Process ID XXXX) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
i think so it is getting this error becasue it blocking it self at one point in the SP
DECLARE cty_Cursor CURSOR FOR
SELECT Country FROM TB_Country
declare @cty varchar(2)
OPEN cty_Cursor;
FETCH NEXT FROM cty_Cursor into @cty;
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC SP_DO_SOMETHING @cty
FETCH NEXT FROM cty_Cursor into @cty;
END;
CLOSE cty_Cursor;
DEALLOCATE cty_Cursor;
i think so it calls the SP then before SP finsih its working it calls it back from cursor with other argument.
how we can make it sure it finish it execution before it is being called again. i think so we need some sort of lock here but i am not able to find right solution . please anyone suggest something.

We've got a 3rd party application that periodically runs SQL commands throughout the day. We've been getting issues with this application showing a sql error:
Transaction (Process ID 71) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
In checking the processes on SQL Server, there were a lot, and process ID 71 was actually hitting a completely different database.
Is there a way to streamline how SQL Server handles processes, and what's the limit at any given time?
Hi Folks,
I am having this table locking issue that I need to start paying attention to as its getting more frequent.
The problem is that the data in the tables is live finance data that needs to be changed and viewed almost real time so what I have picked up so far is that using 'table Hints' may not be a good idea.
I have a guy at work telling me that introducing a data access layer is the only way to solve this, I am not convinced but havnt enough knowledge to back my own feeling up. (asp system not .net).
Thanks in advance

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.

ive seen this Deadlock Error message out on the internet being discussed, but no solution being offered.
i have a windows service that's running Select Statements [one at a time] - so unless there's some command in sql server that would re-run these - it could be a problem for me.
now if im running this select proc manually - of course i see the message and re-run the process, but how can this be accomplished programatically.
see msg below:
Transaction (Process ID 106) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
thanks for any help on this

Hello Everybody,
My name is Fabio and I post from Italy.
First, I don't know if this argument was already discussed in the past, but I'm new in this group so ...
Second I'm not so expert in DB due to the fact that I'm using SQL for the first time in my life ...
I use a store procedure to pass to every single user in my intranet (more than 150), details of different clients taken from an SQL table containing around 30.000 names.
Users have an ASP page displaying the information Selected in the DB.
This means that 150 users display info of 150 different clients.
To to this I use this code in store procedure:
CREATE PROCEDURE sp_assign_name
@iduser int
AS
if exists(select top 1 * from recallornotes where tmkoperator= @iduser)
update nominativitelecom set tmkmotrecall=convert(nvarchar(1), tmkstatus), tmkstatus=7 where id in (select top 1 id from recallornotes where tmkoperator=@iduser)
else
begin
if exists(select top 1 id from nonotes)
update nominativitelecom set tmkmotrecall=convert(nvarchar(1), tmkstatus), tmkstatus=7, tmkoperator =@iduser where id in (select top 1 id from nonotes with (UPDLOCK) order by NewID())
end
GO
This is working quite well when the number of users are more ore less around 50/60, when the number grows, on the IIS server (Pentium IV server, with Win 2000 in English, MS SQL 2000, and 1 Giga of ram), a file called DLLHOST.exe start to use the 100% of the CPU, and the users cannot display any other ASP page on their screens.
It is not a virus (some newsgroup report this problem connect to a worm virus, but we have latest antivirus files installed and spyware detect/delete on).
The SQL log reports this error:
"transaction (process id 69) was deadlocked on (lock) resources with another process and has been chosen as the deadlock victim. rerun the transaction".
Is there a way to avoid the conflict that occur when different users are trying to select the same record in the DB ?
In other terms, which process will you use in the same situation to select one record per user ?
Thanks in advance for your precious help,
Fabio
Hi All,
please throw in any ideas as it matter of urgency.
We have rebuild our 24/7 heavy loaded website using ASP.NET 2.0 and SQL 2005 (we have one active-passive cluster for main activity and 2 active-active clusters to browse static data).
Main cluster is publisher and distributor for replication of data (small subset of it and it works fine).
Hardware is pretty tough - 16 zeons 32G ram, NetApp SAN.
We had no troubles in first 3 days but now it gives us some headache.
Yesterday it failed and website was unavailable for about 5 min. Today happened the same.
SQL Server rebooted - no failover occured - just rebooted on the same physical box as it was before.
The first message I can see :
All schedulers on Node 0 appear deadlocked due to a large number of worker threads waiting on LCK_M_IS. Process Utilization 0%%.
We didnt have any significant lock issues before and havent been expecting them. Yesterday db failed in the morning - which is not a peak time.
Is anyone can advise on what I have to do to find out the real source of the problem. Is it the same for both incidents ?
P.S. We have 3d party monitoring our db and also we have NetApp software doing Snapshot backups on the SAN.

Hi:
On a production SQL2000 STD sp4 server,
1. I have dropped 10 tables with each around 1-2 gb in DB ABC
2. I had run DBCC ShrinkDatabase (ABC, 20) and it is failed after running 133 hours this morning. Yes, 133 hours.
It ran 72 hours last month and shrinked from 200 gb to 180 gb.
Thus, I expected it should be <= 72 hours to fnish since 10 more tables are dropped ?
Msg 1205 Transaction (Process ID 75) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
DBCC shrinkDatabase will cause deadlocking? how to avoid it?
Is there other ways to speed up?
thanks

View 5 Replies View RelatedIn an SSIS package I am continually getting the same error:
"Transaction (Process ID 58) was deadlocked on thread | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
The package is attempting to do a simple Execute SQL Task. Since this seems like a database and not integration services issue, does anybody have any thoughts or insight into this error and where to begin troubleshooting?

This proc will show you what is using SQL system resources right now. If a process is not currently using any resources, it will not show up on the list. Also, a dump of the input buffer is printed so you can see just what is going on.
I use this code whenever somebody whines that "The server is slow!".
The magic is ::fn_get_sql which came with service pack 3 for sql 2000.

Hi,
Im just looking for someone that has a demonstration Visual Basic database script.
Something that makes a database, ad / removes rows and information, does all basic database stuff, just as an example of how a SQL database is supposed to be handled.
Anyone have any links?
I know that a query inside a called UDF does not show up when displaying theestimated query plan, but are the resources (CPU, DiskIO) used by a UDF thatis call from within an SProc or embedded in a SQL statement included insp_who2 and Profiler BatchCompleted?Also how performance draining is it to do something like the following. Iassume for every row returned the udf will be called causing 8000 tablescans on DateTable?Create Functionu udf_GetCountDates (@StartDate datetime, @EndDate datetime)Returns IntbeginReturn(select count(*) from DateTablewhere ColDate > @TestDate and Col1Date <)end--DateTable has 5,000 rowsCreate proc Test@TestDate datetimeAsselect Col1, Col2, udf_GetCountDates(@TestDate, Col2)From OTable--OTable has 8,000 rowsGoThanks,Ray

Hi folks, thought I'd wade into the mssql waters, I've used mysql for some time, thought I'd familiarize myself with the other.
I downloaded mssql server 2005 express edition. Don't know if I missed anything on the site, maybe I did. I've got it running from the command line.
Are there any GUIs out there that are decent to use? Where can I download it?
Is there a specific manual available like mysql has? I think I stumbled across something but wasn't sure it was searchable, sorry the link is on my other 'puter at the moment so I can't see what I was looking at.
perhaps a sticky in this forum with good resources would be helpful to all.
Thanks,

Hello,
There are many Errorcodes which SSIS uses to represent errors, warnings etc.
List of errorcodes are at: http://msdn2.microsoft.com/en-us/library/ms345164.aspx
Now, in my SSIS package, I have defined error handler(OnError) and warning handler(OnWarning) to handle the events. Which logges them to a flat file with some formatting and condition checks including addional information about faulty row.
I dont want to log the exact error messages sent by SSIS as they are too much technical and not understanadble by normal user. I want them to be replaced with some custom message which I 'l pick from some resource file by matching the ErrorCode. One can consider this resource file as collection of key(ErrorCode), value(Custom Error Message) pairs.
In .NET we normally use resource files(.resx) to achive the same task. I found no way to use such resource files in SSIS.
Is there any way by which I can implement this functionality?
I dont want to implement custom logging mechanism as it does not fit into my application needs.
Please guide.
