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.
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?
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).
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?
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?
my freind asked me to look for him for online book or something very good that teach SQL for SQL server 2000 ... what i need is something like hands on examples that will take user from level 1 to level * .... i have seen alot of stuff in google but i think some of you might know what i need and can direct me to better resources as i could not find someting specail !!!
Hi We are facing an acute situation in our web-application. Technology is ASP.NEt/VB.NET, SQL Server 2000.
Consider a scenario in which User 1 is clicking on a button which calls a SQL stored procedure. This procedure selects Group A of records of Database Page1.
At the same time if User 2 also clicks the same button which calls same SQL stored procedure. This procedure selects Group B of records of Database Page1.
So, its the same Page1 but different sets of records. At this moment, both the calls have shared locked on the Page1 inside the procedure.
Now, in call 1, inside the procedure after selecting Group A of records, the next statement is and update to those records. As soon as update statement executes, SQL Server throws a deadlock exception as follows :
Transaction (Process ID 78) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction
We are able to understand why its happening. Its because, Group A and Group B of records are on the same Page1. But both the users have shared lock on the Page1. So, no one gets the exclusive lock in records for update, even though, the records are different.
How can I resolve this issue? How can I get lock on wanted rows instead of entire page?
Devteam writes "Hi, WIndows version 5.0 (SP4) I am using sql server 2000. in our application i am using simple select statement to retrieve the value from the database. Sometime the same query is accessed i did not get the result.i have tried to run the same query using query analyzer. but the query is keep on running. at the same time when accessing other rows in the table, it gets retrieve the values.
what is the problem here... is there anything locked that the row before executing the select statement. if there is any lock is present then how to identify it and also how to prevent a row from locking... if the lock is occured then the other transactions also not executed. why the lock is placed in the first place."
Hi All,I have a table that holds pregenerated member IDs.This table is used to assign an available member id to web sitevisitors who choose to register with the siteSo, conceptually the process has been, from the site (in ASP), to:- select the top record from the members table where the assigned flag= 0- update the row with details about the new member and change theassigned flag to 1- return the selected member id to the web pageNow I'm dealing with the idea that there may be brief, high trafficperiods of registration, so I'm trying to build a method (storedprocedure?) that will ensure the same member id isn't returned by theselect statement if more than 1 request to register happens at thesame instant.So, my question is, is there a way, once a record has been selected,to exclude that record from other select requests, within the boundsof a stored procedure?ie:- select statement is executed and row is instantly locked; any otherselect statement running at that exact moment will receive a differentrow returned and sill similarly lock it, ad nauseum for as manysimultaneous select statements as take place- row is updated with details and flag is updated to indicate themember id is no longer unassigned- row is released for general purposes etcIf what I'm suggesting above isn't practical, can anyone help meidentify a different way of achieving the same result?Any help immensely, immensely appreciated!Much warmth,Murray
I'm not a SQL Server expert, but need to understand something. I'm currently have SQL Server 2000 SP4 installed locally on my machine for application development.
Using sp_lock, I noticed that there are lots of shared database locks. After some study, i produced this interesting script:
use Master go sp_lock go use Experience go sp_lock go
which results in:
spid dbid ObjId IndId Type Resource Mode Status ------ ------ ----------- ------ ---- ---------------- -------- ------ 52 1 85575343 0 TAB IS GRANT spid dbid ObjId IndId Type Resource Mode Status ------ ------ ----------- ------ ---- ---------------- -------- ------ 52 13 0 0 DB S GRANT 52 1 85575343 0 TAB IS GRANT
My question is about the extra lock added by the "Use Experience statement". It lasts as long as the Experience DB connection is open
Question 1: The way I read this is: the "use Experience" statement creates a shared database lock. Am I reading this right?
Question 2: I started looking into this because my application produces lots of locks that seem to live for 15-20 minutes. I have not noticed other adverse side effects of these locks. I have confirmed that nothing I have control over creates transactions, so I do not see why locks would be maintained. Should I be concerned about these locks? Is this expected behavior?
;) 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 ?
I am getting a resource issue on a server for obtaining locks. Looking for ideas. This is a sql 2000 server running on Win 2003 with 16 gig of RAM on a new Dell quad box with data on a SAN. That's the good news. The bad news it is a 3rd party app which I have almost no ability to change. The users connect through Citrix with about 400 concurrent at a time. I was looking at setting a higher min lock issue. yesterday it sent me the dreaded alert Fatal error in resources with this issue and buried the server at 100 CPU for about 2 minutes. Any help or insight appreciated. Most of my standard sql data looks OK, Cache at about 99, system queue at about .8.

And how did I get 4 errors? - I only set my script task result to failure
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. I have installed an SQL 2005 Failover Cluster on a Two Node Active Passive Windows 2003 Cluster.If i am trying to failover from the Active node to the passive Node,The Sql Server,Sql Server Agent and SQL Analysis resources fail,However if i reset the passowrd in the services tab of the above three services on the pasive node,the resources come online. Below is the brief of my setup 1.I have two Active directory domain controllers running Windows 2003 R2 Standard edition with SP2. 2.i have installed a Windows 2003 Two Node Active Passive Cluster as NODE1 and NODE2. 3.The Domain account used to install WIndows 2003 A/P Cluster is Clusteradmin.This account is the member of Administartors on the Domain as well as the Local Admin on NODE1 and NODE2. 4.SQL 2005 with SP2 is installed on both the Nodes as SQL 2005 Failover Cluster.The account used to install SQL 2005 is sqadmin.This account is the member of Administartors on the domain and the member of Local Admins on NODE1 and NODE2. 5.SLQ 2005 has four domain groups for 4 SQL Services.The Services are SQL Server,SQL Server Agent,SLQ Anaylisis Server and Full text Search. 6.Each of these servcie has a seperate service account created for them.All these service accounts areb the members of domain admin and the member of Local Admin on NODE1 and NODE2. 7.Each of these servcies is running under these servcie accounts in the Servcies tab in NODE1 and NODE2. 8.If i fail the resources from NODE1 to NODE2 ,The SQL Server,SQL Server Agent and SQL Anaylisis resources are failing.on going to the service tab of NODE 2 I reset the password for these services,the services come online. 10.The Cluster resources and MSDTC Resources are Failing over successfully.They are coming online successfully. 11,I have a problem with the SQL Server Resources,even if i failback to NODE1 from NODE2,the same resources are failing again.
When I execute a select with an inner join my query is bombing out calling me a deadlock victim. I know what deadlocking is, but I am only doing a select. Why would a select lock records?
Could anyone explain what locking occurs when a select is fired with a join?
We've set up a report farm with two servers, both 64 bit with 4 CPUs each. One has 16Gig and the other 8Gig of memory. We're using Windows NLB and the load test software confirms that the NLB is working. When we run a number of concurrent reports, both servers get utilized, but they only work on a few at a time. The report server queue doesn't seem to be fully utilizing the hardware. From a prior post I've learned that the report server queue automatically runs 4 reports per CPU. This is not occuring for our setup. Has anyone else experienced the same? Are there any configurations that need to be set to open the queue up? The reports are heavy (300,000 records grouped and summed). Does this affect the queuing process?

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.
I have about 50 databases that are only accessed once a month and on a predictable schedule. Would it free up resources on the server if they were kept offline and brought online only when needed ?

Access also uses DAO ,Jet/ odbc to linked tables on SQL Server for many other tasks/forms.All is well when Access 1st run but after a few hours or so the Accessapp grinds to a halt.Upon checking the task manager the mem usuage upto 160MB and handlecount upto 86,000 ! (cpu process % is low).After the "Access Fail" if I stop/start access only, performance isnot returned, I have to stop/start SQL Server.It would seem that allconnections from this PC to SQL server are badly affected, it is nottied to the client application that had the problem.As I could not work out where the problem was I took the Accessfunctionality into a VB6 app, using ADO 2.0, thinking this shouldsimplify matters with Jet and ODBC out of the way.I now have the same problem with the number of handles increasing withevery new timer based function.* code snippet example *If Not OpenConnection Then 'we have not been able to open aconnection to SQL serverCall procLog("Connection failed to SQL server")Exit FunctionEnd If'gVar.cnnSQL is my public ADODB.ConnectionSet cmdSQL = New ADODB.CommandWith cmdSQL.ActiveConnection = gVar.cnnSQL.CommandText = "MyDB.dbo.insert_tblMyData".CommandType = adCmdStoredProc.Execute RecordsAffected:=lngRecs, _Parameters:=Array(lngID, dtDate,intCategory,strNationality,strNotes,strName)End With* code snippet *** After the "Access Fail" if I look at one of my clients, running thesame Access app on another PC, it seems normally responsive when usingone my bound forms to browse the data from same SQL Server **Any ideas anyone ?
The following question applies to SQL Server 8.0.2187 (2000 + SP4+916287/914384/898709/915065/915340):
We have now twice had an incident where the same SQL Server has stopped responding. The only workaround is to restart the SQL Service. After this occurs, the log is filled with the following messages:
2007-09-10 16:42:14.29 spid3 Process ID 197:320 owns resources that are blocking processes on Scheduler 1.
2007-09-10 16:42:14.31 spid3 Process ID 74:324 owns resources that are blocking processes on Scheduler 5.
We haven't been able to pinpoint a cause or reporduce the problem on a dev server. I've seen several posts about this issue online but not many answers. Does anyone have any advice on how to troubleshoot this issue?

Is there a way to write a script ,keep the script in SQL Agent job , run the  job to keep track of Blocked and deadlocked queries and store them in any Table or with triggers?with out Profiler,Audit,activitymonitor ?Â
In 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?
How to restrict resources usage based on individual Databases in resource governor?
We have many databases in one instance; I would like to restrict resource usage to each database respectively.
I created 2 pools as pool_login, pool_DBNAME, and 2 workload groups as GroupLogin,GroupDBNAME, and also the classifier function.After setup above, I use following statement to check what sessions are in each group .
Even if there are spids which are accessing database DBNAME, I can’t see that they fall into the group GroupDBNAME and pool pool_DBNAME.
SELECT s.group_id, CAST(g.name as nvarchar(20)), s.session_id, s.login_time, CAST(s.host_name as nvarchar(20)), CAST(s.program_name AS nvarchar(20)) FROM sys.dm_exec_sessions s INNER JOIN sys.dm_resource_governor_workload_groups g ON g.group_id = s.group_id ORDER BY g.name GO
Following is the code to create pool, group,classifier function:
USE master GO; -- Create a resource pool pool_login. CREATE RESOURCE POOL pool_login WITH
[Code] ....
-- Create a workload group to use this pool.
CREATE WORKLOAD GROUP GroupLogin USING pool_login; GO CREATE WORKLOAD GROUP GroupDBNAME USING pool_DBNAME;
[code]....
-- Register the classifier function with Resource Governor.
ALTER RESOURCE GOVERNOR WITH (CLASSIFIER_FUNCTION= dbo.rgclassifier_v1); GO
