we have tables that load overnight. Sometimes a user will try to run a query up against that table while the table is loading and a deadlock occurs. I do not notice this until I get into the office. By this time many tables have not loaded. Is there a way to have SQL6.5 automatically Kill deadlock processes.
View 1 RepliesIf I kill a blocked process, why does the current activity window still show the process? Both processes, blocking and blocked, are scheduled tasks. Also, the blocked process is still listed as a running task in the manage scheduled task window.

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
One DTs package job running and we stop the job.Job was stoped but process not killing.We tried using kill spid but no use.please any body give suggestion. this production server.
Dear SQLGuru,
I hope you can help me to find the way to resolve this issue.
When I've accidentally triggered a process in SQL 6.5 without knowing that it's going to hold a lot of resources and making the network very slow and end users will be started complaining about the slowness.
I've no other way other than the killing the process kill <spid>. Funniest part is, even it is not get killed even when I tried multiple times and the process is still active and still running.
When I tried to find the way out, One another guy stopped the SQL server and restarted again. That's it, it took a long time to stop and restart and ends up with the recovery mode of the database and it was running more than 3-4 hours to get into the usual mode.
Based on the scenario, what would be your suggestion when I've encoutered the same situation. I've triggered some application like DBCC checkdb and it's keep running for a long time. But I need to kill the process immediately without affecting any other process. Pls. advise me.
Thanks a lot,
Naga
If we have a deadlock we will check in the error log and and find the spids which are involving in the deadlock.
We will kill one of the process by using SPID (no) KILL.
Is there specific steps to consider while killing a process
Hi everybody,We have a very large database and high transaction volume. Time to timethese transactions are locking each other and decrease the performanceof the database. Is there any way that I can automate the killingprocess when blocking and deadlock time is exceeded in certain timeelipsade? Can somebody help me on this please?Regardsasa.
View 6 Replies View RelatedI am having a few problems using ASP-DB advertised on this site. Queries that were working rather quickly a week ago are timing out for no apparent reason. (asp-db seems to be buggy)
I have no idea as to what is causing the query (ie select * from tables X, Y, Z) to time out. The process id on SQL server says AWAITING COMMAND or SLEEPING.
Also, the processes on SQL server do not seem to die. Can this be accomplished via ASP or other means.
All help is greatly appreciated
Thanks

I ran a DBCC SHOWCONTIG on a large database. Because the execution was taking longer than I wanted I cancelled and then killed the process running the DBCC. This action seems to have abnormally ended SQLServer and subsequently crashed the entire NT server. Have you experienced any behavior similar to this when using DBCC and/or killed processes?
View 3 Replies View RelatedWe are using SQL server 6.5 and currently have about 100 users connections at a given
point in time. The application is Visual Basic 5.0 based and it allows users to create
MS Word documents from the application. These documents names are stored in a table which basically
acts as a reference table. Every time a document needs to be attached to a record
this table is called with an insert/update query. This results in an exclusive page/table
lock and ends up into a blocked process. This finally results into a major halt for
all the system users.
Manual killing of these blocked processes frees up the resources and brings things back to normal
although disruptive to the users.
Any clue as to why the blocked processes are not able to free themsevles up ?
Are we missing something in our SQL configuration that will help us with unblocking
these processes ?

Has anybody experienced a process being blocked by SPID -1.
Hi,
I have a fairly complex application running which has numerous connections on various threads accessing my sql 2005 database.
Every now and then I find that one of my connections is being blocked by process with a pid of -2.
I assume this is some system process.
The only way I can get my application going again is to restart the sql server.
Can someone tell me what process -2 is?
cheers,
Robert
I have a question about blocked processes. My manager wants to know how you can know the following when a blocked process is encountered.
The job, program and the statement that is causing the blocking. I have figured out how to determine the database involved but not a lot else. Such as in the blocked process report there is a waitresource field. How to you decipher it?
The report also tells you the client application, but in this case it just states the Micro focus Net Express as the client, not the job or program that is running.
I have an inputbuf listed but it just shows the database id, and the object id. And I am not sure how to locate the object id in this case, I am guessing sys.objects, but I do not seem to find that one.
I have read many things on MSN about the blocked process report, but it does not seem to go into great detail.
I seem to have all the pieces, but do not exactly know how to quickly tie them all together.
Any help would be appreciated.
Thanks,
Kathy
According to BOL you can configure an Alert to notify you when the blocked process threshold has been exceeded:
SQL Server 2005 Books Online
blocked process threshold Option
Use the blocked process threshold option to specify the threshold, in seconds, at which blocked process reports are generated. The threshold can be set from 0 to 86,400. By default, no blocked process reports are produced. This event is not generated for system tasks or for tasks that are waiting on resources that do not generate detectable deadlocks. For more information about deadlock detection, see Detecting and Ending Deadlocks.
You can define an alert to be executed when this event is generated. So for example, you can choose to page the administrator to take appropriate action to handle the blocking situation.
Can someone provide some direction on exactly how this is done? Does it require a Service Broker and queue?
guys,
I have a stored procedure which gets called by ASPX page and it inserts, updates data into different tables. originally, I had a issue that if error occured, it would not rollback all the data so i used transaction around it. now, once in a while I am getting this error "System.Data.SqlClient.SqlException: Transaction (Process ID 181) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction".
I don't know how this error occurs and how do I prevent it. please help.
transaction is as follow.
BEGIN TRY
BEGIN TRANSACTION
// t-sql codes to insert update multiple tables
COMMITEND TRY
BEGIN CATCH
if (@@TRANCOUNT > 0) --error
ROLLBACK
declare @errSeverity intselect
@errMsg = ERROR_MESSAGE(),
@errSeverity = ERROR_SEVERITY()
RAISERROR(@errMsg, @errSeverity, 1)

I'm going to try to explain my situation.
I have a spid that I'm not able to kill, this were a select statement from with in access 97 application using a DNS connection.
So even that I reboot the client pc and kill the spid it still shows as active with status RollBack.
We have similar problem before and the only way that it disappear were re - starting Sql.
(system Sql 7.0 with sp1 and Access 97)
Thanks.

Is there a way to kill all user connections to a database using T-SQL?

if we kill sp, let's say, on the third statement, will the first two
be rolled back (undo) ?
I wish to select processes from sysprocess that are SLEEPING and more than a certain time old (say 10 minutes) so that I may KILL them. I can get the query to do the select, but how do I KILL the process? I have tried selecting the SPID into a local variable and then trying KILL @var_name, but I get "Incorrect syntax near '@var_name'".
I have tried all of the resources that I can find, but without success. Is this possible? If so, how do I go about doing it?
Thanks in advance.

All,
Is there a way to have SQL server automatically kill a spid when its result set gets to be larger than a specific threshold( eg 3 gigs) ?
Any help is greatly appreciated: any sample stored procedures or code library for doing something like this?

Hi Peepz! my problem is this i am managing more than 3 servers which has a many users. this servers have one common problem. the most users uses high cpu utilizations what make it worst is even if the process is already done for a long time (status = sleep) they still uses high cpu or IO utilization. One time i ask to confirm one user if they are really having that process and found out that the user have gone home already and no other is using thier computer. And assuming that we have more than 20 users with the same case it really make the server slow and occationally hangup. i try to kill these process/user but i think killing is not an option. Kindly help pls. are there any way to refresh connections or terminate it, how do you handle this situations?
Thanks,
Keez.
