XML Services And SQL Server Orphaned Processes

May 1, 2007

Hi

Wanting to know how do you detect and kill orphaned spid in SQL Server left behind by an XML service which was not completed normally. The client requests an XML service which open a connection, and due to network problem the client did not manage to call the another service which suppose to end the connection. Thus leaving behind in SQL Server orphaned spid which continue to hold locks. This created problem when the next user wants to access the resource.

The simplest way is to get all spid which are holding locks for more than a certan period and kill them. Is there a better way to actually detect orphaned spid?



Help much appreciated.



regards

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

How Can I Kill Sleeping Processes In SQL Server?

Sep 14, 2006

Dear, Our ASP.NET scripts send SQL statements (as inline SQL or SP) to process the requested job. After the job execution, the process ID stays in the server and waits for next command with sleeping status.Since this process does not go away, next job adds another process and eventually, the server is overloaded with these processes and dies. How can I kill this sleeping processes?Regards,Echo

Multiple/Duplicate SQL Server Worker Processes

Nov 18, 2005

I don't even know where to begin looking... I have a page that loads multiple web user controls...
I know I use one connection object class that is used in all my objects when executing the query (calling Stored Procedures).
The problem is when the first page is rendered and each user control queries the database (SQL Server),
it eventually slows down.  In my controls, I use a lot of repeaters and internal queries per each repeater item.
So I know it hits the database quite often. 

Problem is when I look in SQL Server Enterprise Manager Process Info, I have multiple worker processes sleeping.
My first thought is ASP.net is creating a new session connection (process) to the SQL Server?  Why?  How? 
What do I do to check either my code is creating the connection object properly.  Thanks!

SQL Server 2008 :: Processes That Update A Certain Column

Oct 26, 2015

I have a table and a specific column inside this table. I know this table is being updated, by using sys.dm_db_index_usage_stats, I was able to determine this, by some process (stored procedure / SQL Job / etc), but the problem is, I am not sure what process is doing it.

How would I search our SQL Server 2008 database to find any process that manipulates this table / column (I only care about Inserts / Updates and Deletes, but do not really care for SELECT).

SQL Server Down: Process ID 121:406 Owns Resources That Are Blocking Processes On Scheduler 4.

Sep 11, 2007

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?

Table Loads From DB2 - Parallel Processes, Linked Server, And Lightweight Pooling Issue

Aug 17, 2007

Hello. I have a 32-bit SQL 2005 (SP1) server that is my current Production server. I also have a 64-bit SQL 2005 (SP1) server that will become my Production server. I have several SSIS packages that load/refresh data on a nightly basis to a few of my databases from DB2 (MVS). I have the packages setup on the current Production server (32-bit) and all is working well through the Microsoft OLE DB provider for DB2. However, on the 64-bit server, I am experiencing some issues with the SSIS packages failing due to large loads. Loads that are loading tables with 500K, or less, data seem to run without issue (through SQL Agent Jobs). But, larger table loads are failing.

I do have a linked server set up on the 64-bit server to the 32-bit server, for other processes. And because of this I have lightweight pooling turned off on the 64-bit server (because of distributed querying). Lightweight pooling is turned on on the 32-bit server. Could this be what is causing some of my issue? Since I don't have the lightweight pooling option turned on (on the 64-bit server), am I not getting the proper amount of through-put for my 8 dual core CPU server?

Thanks
Scottye

Empty Warning Box Appears With Only OK Button (2 Processes Started) When I Open Microsoft SQL Server Management Studio

Sep 4, 2007

Hello,

I'm new to SQL server 2005. I installed SQL server 2005 and had some problems with the original install. I therefore uninstalled SQL server 2005. Rebooted and than installed SQL server 2005 again. Everything appears to have installed correctly except for the fact that when I start SQL Server Management Suite I get 2 copies running in the foreground. The last copy of the SQL Server Management Suite shows a dialogue box that contain a warning sign (yellow triangle) with no text but an OK button is in the dialogue box. When I press the OK button, this instance of SQL Server Management Suite kills itself. The first instance is now given window focus and it brings up the "Connect to Server" dialogue box. I can connect to my local server and run a script to add columns to the database. But everytime I bring up SQL Server Management Suite, I always end up with 2 copies running and I have to hit the OK button to get rid of the second copy. Can anyone help me get ride of this annoying problem?

Orphaned Indexes?

Jan 14, 2000

As I do analysis on a database I am finding multiple clustered indexes defined on a single table.
I know this is not possible since SQL Server only allows one clustered index per table.
With more research I found these suspected clustered indexes have a corresponding row in
sysindexes but without a correlating id match in either sysobjects or syscolumns.
Is this orphaning of indexes common and what is a recommended solution.
Thanks,

Orphaned Transactions Problems

Mar 10, 2008

so i'm having a bit of a bad day today

i have an app that starts a transaction (some deletes, etc...)
in the middle of this transaction the connection drops (say we pull out our network cable) but this will leave the transaction still running and it will be orphaned.
i know i can kill them in sql server, but what i'm looking for this to somehow not happen at all.
I tried SET XACT_ABORT ON but no luck.

Is what i need even possible?

Mirroring And Orphaned Users

May 29, 2006

Hi there!

There is still a problem with mirrored (mapped) SQL Users. If you mirror a database where an application connects with an sql user, the mapping (login / user) will be lost on the mirror server. After a failover occurs, it it not possible to log onto the new principal database because the database use will be an orphaned user and has to be remapped to the login (using sp_change_users_login 'update_one', 'user', 'user').

Is there any chance to do it in a system trigger? What is the firing event after the failover occurs? I've tried something like following, but it doesn't fire.

alter TRIGGER map_orphaned_users

ON ALL SERVER

FOR ALTER_DATABASE

AS

execute sp_change_users_login 'update_one', 'easyris_41', 'easyris_41';

Someone an idea how to automate these usermapping after failover on the (new) principal server?

SQL 2000 Orphaned Connections

May 24, 2007

We have 4 sql servers which service 4 load balanced web servers (with sticky sessions) and we recently brought one of the four SQL servers online.



In the last week the new SQL Server 2000 Standard (SP4) has been exhibing orphaned connections and attempts to use invalid connections out of the connection pool on the app servers. This manifests itself in General network Errors and Timeouts (when the sql is not really doing much other than simple table requests).



Does anyone have any experience in what might be causing this on a new server. I've asked our networking people to verify that the network routing and firewall are set the same as the other three servers. The application is the same acrossed all of the app servers so I've ruled out any issues with the application not closing connections.

Orphaned SQL Logins On The Mirror

Nov 20, 2006

Hi there,

I€™ve recently set-up database mirroring between two servers in the same domain: DMZSQL01 and DMZSQL02 with a witness of DMZSQL03.
The mirroring as all gone according to plan.

Set up all the users/databases on the Mirror (DMZSQL02) and then do a back-up/restore to sync the databases and then enable the mirroring, this has all gone fine and we have lots of synchronised/mirrored databases now. However, if I do a failover the logins on the mirror are not valid, they are in SQL Server and also the database but they don€™t work. I€™ve read through other posts and found links to this SQL Server article:
http://support.microsoft.com/kb/918992/

This has had no effect though. Do I need to remove everything off my mirror and start again setting up the users first and then doing a backup/restore or is there some other way. Both servers are reporting the SID€™s are the same for the logins which do not work. However the principle_ID is different, I'm quite sure if this is a problem or not??

Can anyone point me in the right direction of what to do next? Or have any ideas.

Thanks
Ed

Orphaned/Hung User Process

Jul 21, 2000

Hi,

Looking through the archives, I didn't see any articles that specifically addressed the problem, so here it is:

SQL 7.0, NT4SP6, 2G ram, 4x

I've got a user process as follows:
Status: ROLLBACK
Command: SELECT
Application: Enterprise Manager
Wait Type: EXCHANGE
Login time: 06/25/00 4:07:05AM
Last batch: 06/25/00 4:07:20 AM
The last TSQL command batch is a correlated subquery with grouping...

Apparently it hung and the user quit ungracefully.

No other processes are blocking it, but periodically it blocks other processes, including some index maintenance I need to perform.

I have tried to kill it with Enterprise Manager and with the KILL [id] command. Neither have worked.

Mgmt is reluctant to bounce the database, as am I.

Any ideas?

Thanks in advance!

Orphaned User Accounts When Restoring

Dec 29, 1999

I am copying a database to an alternate server by restoring a full backup onto the new server. However, whether I create the logins prior to the restoration or not the user accounts in the database no longer map to logins in the master.

Unfortunately it is not simply a case of dropping the acounts as they own objects in the database.

My best solution to date has been to use the sp_addalias to alias logins of the same name to the original user. However this is a far from ideal situation as one cannot readily tell that the logins are aliased and there must be an additional overhead in doing this.

Replication - Orphaned Distribution Agent

Dec 9, 2002

Any help would be appreciated.

SQL 2012 :: Cannot Drop Orphaned Account

Dec 30, 2014

All is happened when a server crashed some weeks ago and it was removed from my network. After that, under my SQL Server 2012 I get an orphaned account which cannot be removed. This account is a computer account related to an old SCOM installation.

If I try to execute the command DROP USER [NETWORKSERVERNAME$] I get the following error message:

The database principal has granted or denied permissions to objects in the database and cannot be dropped. Msg 15284, Level 16, State 1, Line 1

The database principal has granted or denied permissions to objects in the database and cannot be dropped.But if I run the following command to know all permission granted to the account, I get an empty result:

select * from sys.database_permissions where grantee_principal_id = user_id ('NetworkSERVERNAME$');

Furthermore, following the instructions provided by the official KB for troubleshooting orphaned users, I get another error [URL].

sp_change_users_login 'update_one', 'NetworkSERVERNAME$', 'NetworkSERVERNAME$'
Msg 15291, Level 16, State 1, Procedure sp_change_users_login, Line 114
Terminating this procedure. The User name 'NetworkSERVERNAME$' is absent or invalid.

The only thing I can retrieve is 15 permissions that this account granted to another account in the past:

select *
from sys.database_permissions
where grantor_principal_id = user_id ('NetworkSERVERNAME$'
--
class class_desc major_id minor_id grantee_principal_id grantor_principal_id type permission_name state state_desc
17 SERVICE 65538 0 5 19 SN SEND G GRANT
And more 14 rows…

resolve my issue and safe delete the account SERVERNAME$? I need this because I have to reinstall SCOM with the same computer name on another server, but installation fails due to this behavior.

Deleting Orphaned Data - Maintenance

Dec 10, 2007

Hi,

I really don't know how frowned upon my approach is here, but it was the only way I have been able I've been able to do it.

On my application, when users delete their account, it sometimes brings the db server to a COMPLETE crawl. The reason is some users who delete have many years of related data, and when the data deletes with them, its very slow.

To avoid this I've taken off many contstraints, and I do have some sprocs that deleted orphaned data at night.

thoughts on this approach ?
