DB Engine :: Single User Mode Session Lost After Background Processes Jump In

Nov 28, 2012

We have an application running on SQL server. This application restores DB very frequently using Single user mode. Following are the SQLs that are executed to restore the database in single user mode and to get the database back in multi user mode.

alter database [test-db] set single_user with rollback immediate; --This sql is run using test-db
use master;restore database [test-db] from database_snapshot = 'snapshot_test-db';
alter database [test-db] set multi_user;

After switching the test-db to single user mode some 4-5 background processes of Taskmanager jump in for the test-db kicking off the session that application has taken over in single user mode . These background process are deadlocked between them selves.

Please refer to the output of sp_who2 below at link [URL] .... and following is the deadlock XML.

NOTE: SPIDs in deadlock XML may differ from the output of sp_who2 as spids keeps on changing for these processes.
<deadlock-list>
<deadlock victim="process4bbfc78">
<process-list>
<process id="process4bbfc78" taskpriority="0" logused="10000" waitresource="DATABASE: 5 " waittime="705"

[Code] ....

On searching for this problem I found out that people have faced similar problem but I was unable to find out the root cause and debug steps for this problem. Stopping the SQL server is provided as a solution to kick out these background processes but this is not a feasible in our case as code to restore DB runs very frequently resulting in this problem at a good frequency.

I also made sure that SQL Server Agent is not running. The SQL services running on server are SQL server, SQL Server Browser and SQL Server VSS Writer.

Async Processes - Help !!

Feb 10, 2000

SQL7 SP1 NT4 SP5

Hi.

Very long story and I will not bore you with it. What I need to do is call a stored procedure and from within that stored procedure, initiate other sp and get out before those other sp are finished running.

I know I can execute a job but my volume would be about 1 job per second with a life of 2-5 seconds. So in a very short period of time, I can stack up a large volume of jobs.

Anyone have any better ideas ?

Help Please !@!!

SQL Performance And Processes

Mar 16, 1999

I have an SQL server with several (100) users connected. When I run a long running process, it severely impacts user performance. The long running process is a store procedure with several cursors.

Are there SQL configuration settings that would reduce the impact of these long running processes on other Users?

Kill Processes

I have been needing to disconnect users often, before backing up a database or setting it to restricted users.
Each time, I have to go to Current Activity & kill one process at a time. Is there a way, by which I can kill all processes on a database or force out all coonections to it?

Thanks.

Can you kill processes in SQL Server 2K without stopping SQL Server and restarting it? I am using sp_who2 to get a list of active users and I see some accounts that are logged off but still showing up and I am trying to find a way to Kill these accounts and the processes they are doing.

DAO &> SQL Server Processes

Oct 24, 2005

I need to know exactly what VBA lines Create and Destroy SQL ServerProcesses - i.e. those visible in Enterprise Manager under Management[color=blue]> Current Activity > Process Info.[/color]Why?I am experiencing strange behaviour with Processes that are createdwhen I create a DAO Database Object with the following line:Set m_ResDatabase = DBEngine.Workspaces(0).OpenDatabase(strDSN, False,False, strODBC)This creates the process as expected.However the following lines don't always close the ensuing Process:If Not m_ResRecordSet Is Nothing Thenm_ResRecordSet.CloseSet m_ResRecordSet = NothingEnd IfIf Not m_ResDatabase Is Nothing Thenm_ResDatabase.CloseSet m_ResDatabase = NothingEnd IfIf Not m_ResWorkspace Is Nothing Thenm_ResWorkspace.CloseSet m_ResWorkspace = NothingEnd IfIt seems as if SQL Server keeps hold of the first two Processes andthen will release any subsequent ones.Can anyone shed any light in this - or any good web pages where Imight find some answers?Regards Chris

No Processes On The End Of PIPE

Mar 3, 2006

I had to move my developed software onto another computer in order to demo this. The new computer has IIS installed as well as VS2005 and SQL Server 2005. When I try to execute I get this error.



A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)

I have worked on this problem for two days now and have to demo it first thing Monday. Any help would be appreciated.

Background Jobs

May 20, 2008

Hi,

I am a bit hazy on what exactly are background jobs with respect to SQL. Can someone provide or point me to an example which will help me return some results for the view "sys.dm_exec_background_job_queue".
I understand that because background jobs may be short lived it is not quite easy to view or capture them.
Any help will be appreciated.
Thanks,
Karun

Text As Background

Oct 4, 2007

Hi,

I would like to know how can I put some static text in the background of my report.
I thought that it should be as easy as placing textbox, fillling it with text value and setting ZIndex. Everything is OK in ReportViewer control and when I save rendered report as PDF file (text is behind other fields, for example behind table). But when I save my report in Excel format (*.xls) text is placed below other objects, not behind them as it should be.

Any suggestions?

Regards

Background Replication

May 31, 2006



We are developing a embedded system based on Windows CE 5 and SQL Server CE 3 in C++ where we need to do merge replication in background while the front end application still need to perform operations on the database. A solution would be to run the merge replication on a separate thread while the application thread still can access the database to do inserts and updates. I have been researching if it is possible to access the database with queries during a merge replication, but I can not find an answere. Does anyone have experience of this and generally know if it is possible to implement with SQL Server CE 3 in the native API?

Best regards

How To Increase The Maximum No. Of DB Processes?

Sep 4, 1998

I am receiving an error from my ODBC driver “Maximum number of DBPROCESSes already allocated.”

I confirmed that there are 25 connections and that this is the default. This is caused by error message 10029, SQLEDBPS, when the maximum number of simultaneously open DBPROCESS structures exceeds the current setting. I would like to increase this maximum.

I have found only two ways to do this. One is using dbsetmaxprocs using C and the other is using SqlSetMaxProcs using Visual Basic. My problem is that I am interfacing to SQL Server using a third party tool that is doing the lower level programming.

Is there some way that I can increase the maximum number of DB processes for all databases that are part of the SQL Server 7 environment, or can I set this value using a program that is called from a stored procedure?

Any ideas in this area will be greatly appreciated.

Automated Killing Of Processes

Aug 30, 1999

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.

Defing Business Processes

Feb 12, 2007

Sorry, didn't quite know where this should go.
I'm reading Kimball Group's "Microsoft Data Warehouse Toolkit"
Has anyone got any experience in defining business processes? I'm struggling a little to look at my employer's recruitment busines and work out exactly what the real processes are.
Or maybe one of you has read something somewhere about this specific skill?

------------------------
Me: What do you want to know from your data warehouse?
Client: Err...Emm...Everything
Me: OK, that's great. That's all I need to know. I'll see you when it's done.

Limiting Active Processes?

Jul 23, 2005

We currently have a routine that "forks" out (to use the unix term)TSQLcommands to run asynchronously via SQL Agent jobs. Each TSQL commandgets its own Job, and the job starts immediately after creation.Sometimes we can have too many of these jobs running at the same, andthe box crawls to a slow speed until the jobs finish up.Is there a way we can limit the number of active jobs running under theSQL Agent at one time? Or is there away to limit the number of active(runnable) processes on SQL Server, in general?

How Xml Could Help Us With Our ETL Processes On Daily-basis?

May 26, 2006

Hi all of you,

I'm just a newbie with XML. Now we're moving all our DTS to SSIS packages. Most of them are simply processes that takes a plain file and loading these data into Sql table or in inverse way. So that I wonder what role will play XML here.

I mean, are there big differences between store data as XML format and nvarchar?

That sort of stuff.

Thanks in advance for any input,

Have Plenty Of SQL Background Just Not In MS SQL 2000

Oct 9, 2007

Hello all

I have a strong SQL background, but have never worked on MS SQL 2000. I have a deadline to create a file by the end of the week.

I need to extract data from a table within one of the data files on our server. I need to then output that data into a text format and place it into a folder under the C: Drive.

I have been able to create my SQL statements using the Query Analyzer and have had success in generating the results into a crude text file using the Print Statement with a variable that contains the concatenated data fields and the results to file option. Now that the SQL produces the data required, I need to know how to automate the SQL to run every night and how to achieve the "results to file" when executing the SQL.

I did figure out somewhat how to schedule a job, however I am unsure if in the Command box for the step I can just enter my SQL Text. In addition, I could not find any way to indicate where I want the results to go.

Any thing from suggestions of what to read to outright step by step directions would be greatly appreciated.

I can be reached at fcarpenter@merchantsgroup.com

Running A SP In Background (Asynchro)

Oct 11, 2006

Hi all,

I'm calling a PHP page that run a stored procedure. The SP contains a xp_cmdshell command that runs a DTS package. This DTS package is HUGE and will take many hours to import tables from an Oracle database to SQL Server. But I don't want my PHP page to "hang" in the process...

How can I execute my PHP page and refresh it every 30 seconds to see if the importation is done ? In my actual code, I create a "start_file.txt" when I begin the importation and a "end_file.txt" when it's done. I want to refresh every 30 seconds to see if the "end_file.txt" is created and display a "Importation Done!" message.

To be able to do that, I need the DTS Package to run in the background of the web server, or asynchronously from my PHP page.

Simple (stupid) question: is it possible to create a SP to call my main SP so it will run independently ??

Let's review some of my code here.

Part of my PHP page:
$DTS_result = $dbj->Execute(mssql_query("EXECUTE Run_DTS_Packages"));

My Stored procedure (without username & password...):
CREATE PROCEDURE Run_DTS_Packages AS
exec master.dbo.xp_cmdshell 'C:Progra~1Micros~380ToolsBinnISQL.EXE -S RHEA -U user -P pwd -Q "ISQL_Batch ''D:DDFIImporteIMPICAFI.bat''" -n -d DDFI'
GO

Any help will be greatly appreciate !!

How Do I Do This Is SQL Server? (from An Oracle Background)

Jul 20, 2005

SQL Server 2000 Ent, PowerBuilder 6.5 Ent, Window 2000 ProHi,My only experience is with Oracle,so please bear with me...We have some new clients that require our pricing data be importedinto their Sql Server databases. The price lists are in Excel files,which we recieve from numerous vendors on a quarterly basis.In Oracle we take the following steps:1. Import this data into tempory tables using bulk import utilitycalled sqlLoader.2. Then we have procedures that parse in the data to our various pricetables.3. Next we export the tables to a '.dmp' file. (contains table dataand table definitions I think).4. Then the clients download the .dmp file5. Our client application is then used to drop the price tables ontheir local db. and import the .dmp file.Can anyone point me in the right direction by telling me how toapproach this using SQL Server?Thanks,Karen
