Hi
The system tables syslocks,syslockinfo give information on locked resources, spid, object_id,lock mode, lock status etc.
How will i get object_name
for example if a table is being locked above sys tables give object id, how can i get the actual table name ( object_name)
Please let me know
Best Regards

How to export the dead lock information to the user ?
View 2 Replies View RelatedI simply made my script task (or any other task) fail

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?
Please advice. Thanks a bunch.

I want to be able to see when records have been added to a table. The issue is we have a DTS job scheduled to run every night. The developer who wrote it password protected it and doesn't work here anymore. I want to add a step to this series of DTS jobs and want to run it just prior to his job. Is there a way to see when the records are being added or when this job is being run? Thanks again, you guys are the best.

Hi,
I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.
From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"
Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)
I "sometimes" get the following error:
OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.
Help would be appreciated!
I have seen other posts on this but, not able to relate the solution to my scenario.
Hi All,
I have seen a few other people have this error.
Package works fine when run from BIDS, DTExec, dtexecui. When I schedule it, It get these random errors. (See below)
The main culprit is a variable called "RecordsetFileDIR" which is set using an expression. (@[User::_ROOT] + "RecordSets\")
A number of other variables use this as part of their expression and as they all fail, pretty much everything dies.
I have installed SP1 (Not Beta) on server. Package uses config files to set the value of _ROOT.
The error does not always seem to be with this particular variable though. Always a variable that uses an expression but errors are random. Also, It will run 3 out of 10 times without a problem. I am the only person on the server at the time.
Any ideas?
Cheers,
Crispin

I have developed a great intrest in the MS SQL Server recently. I was just wondering if it was worth putting my time into learning this system. In the members opinion would SQL server be technically fit? Does it have a good campacity and flexibility? These areas are quite important to me. I would also like to know how web friendly the server is and its ability to handle complex data.
Any help would be much appriciated.
I have a Sql Express Database that I want to access from a remote tablet application. When the remote user accesses a record (which is a form + ink), I can't have anyone else accessing that record and drawing ink on the record's form, unitl the first user is done. How do I prevent access to that record in a user friendly way until the remote user is done and has updated his changes to the database?
thanks!
Hi there,
I just wrote an article on how to Lock Down SQL Server 2005 that might interest people here. It has step-by-step instructions and SQL scripts for server and database hardening. A lot of concepts are explained along the way.
As an experiment I also have a world-accessible SQL2005 shell to let people experiment with a hardened database and see if they can do privilege escalation. A lot of the standard tricks have been tried so far and the server has held up without any problems. I wonder if that will last
Anyhow, the article is here: http://duartes.org/gustavo/articles/Lock-Down-SQL-Server-2005.aspx. I appreciate all feedback.

Hello,
There is Production server with different Unicode Id and its standard edition, I need to build the server with same configuration of production server, Can anyone help me as to how to get all the info of the server
Thanks
Ekta
That is to say, from a management perspective? I've been asked to provide one, as I'm the first DBA there ever, but I'm not sure what depth of info they want. And, does anyoe have scripts that can perform the audit, or an actual example audit?
I'd imagine an audit should encompass the following:
Database names;
Database sizes;
Location and size of data/temp/log etc. files;
Hardware specs (cpu/memory/disk sizes);
Number of logins;
User applications.
I'm sure that's only the tip of the iceberg, I'd be grateful for your input!
Thanks in advance,
Jaybee.

View 2 Replies View RelatedHi,
I want to lock a table so others cannot lock it but able to read it inside transactions.
The coding I need is something like this: set implicit_transactions on begin transaction select * from table1 with (tablock, holdlock) update table2 set field1 = 'test' commit transaction commit transaction
I have tried the coding above, it won't prevent others from locking table1.
So, I changed the tablock to tablockx to prevent others from locking table1. But this will also prevent others from reading table1. So, how can I lock table1 so others cannot lock it but still able to read it?
Thank you for any help
I have two servers (lets call them sA and sB) connected from sA -> sB via a linked server (i.e. sA pulls data across from sB).
I'm building a temp table full of stock symbols on sA, and then I need to update some values on sA using content on sB. The tables on sB are very large (about 500m rows) so I don't want to pull even close to everything across the linked server. Ordinarily I'd do this by joining to the linked server table, but the target table needs to have nolock on it due to their high use.
update t
set someValue = s.SomeValue
from #myTab t
inner join lnk_sB.xref.dbo.Symbols s with (nolock)
on t.id = s.id
From reading around I gather that nolock doesn't work across linked servers. It was noted in another SSC article that you could use nolock by using an OPENQUERY, but then I can't join to my local temp table, and I end up pulling all .5B rows across the linked server.
Is there some way I can limit the content on sB by my temp table on sA but still use nolock?
I need to lock a table in SQL Server. The reason is that I need to insert a value into an identity column (rather than just taking the next sequence number). I have a program that:
1. Sets identity insert on
2. Inserts into the table
3. Sets identity insert off
The problem is that I believe I should lock the table before I turn identity insert on (otherwise, other transactions will fail). I need to ensure that no other operations will take place on the table while I am doing all three of these steps.
I believe I can set the isolation level, but I cannot find any way to establish the lock without executing the update statement itself - which is a nanosecond too late to prevent another user from getting an error.
I have a 3rd party app which gets the error below on my sql 2000 box. I can't change the app or the db, so I am going to need to tweak sql to make the plane fly. The box is a new dell quad attached to a SAN. Runs on Win 2003 with 16 gig of RAM. 450 concurrent users. Anyone think more memory would help? I have the locks set to default. Are locks more of a memory killer, or CPU?
Error: 1204, Severity: 19, State: 1
The SQL Server cannot obtain a LOCK resource at this time. Rerun your statement when there are fewer active users or ask the system administrator to check the SQL Server lock and memory configuration.

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."
We have an old VB6 app using a SLQ Server 2005 database.
This database is also used by a web service.
When accessed just by the VB6 or WebService everything runs smoothly.
The problem occur`s when both access the database in parallel.
Our web service seem`s to encounter some very long delay for queries running just fine when is alone.
Now my knowledge of VB6 is very limited (and it will stay that way :) i`ve checked the code for access part and some parts look obscur.
so here is the part where the queries gets executed
Set m_adoRecordSet = New ADODB.Recordset
With m_adoRecordSet
.CursorLocation = iCursorLocation
.CursorType = iCursorType
.LockType = iLockType
Set .ActiveConnection = objConnection
.Open m_strSQL
End With
i looked everywhere in the code and iCursorLocation is mainly always SQLClient. i think only one time is SQLServer.
iCursorType is always SQLForwardOnly and iLockType is always SQLReadOnly.
now the curious part (for me) is that the connection (objConnection) is opened at the beginning of the app and never closed? Is that normal in VB6?
Would the cursor being sometimes on the server be the problem?
If someone could help it would be very appreciated.
If you need more details just tell me.
thanks

I have written an app that will allow you to send a query to Teradata, return the results into a Reader and then Bulk Copy that data into SQL Server 2005.
If the query results in a large dataset (ie 20,000,000 rows) is processed then while that data is being bulk copied into SQL Server, using the SQLBulkCopy class, then it prevents users on other computers from logging into SQL Server Management Studio.
Those that are already logged in are shut down also. Everything appears fine to the users but queries do not finish running.
Everything immediatly starts working as normal when either my program finishes or I shut down my program.
Is there any type of property to the SQLBulkCopy class or any other function that will prevent Management Studio from locking up?
Thanks

I'm wanting to start to understand SQL Server. I've got the Beta Version of MS SQL Server 2000 and was wondering whether I could install this on my Windows Me box and start developing? Is this wise, or should i not use the Beta version? Is there a time when the Beta version "runs out"?
Are there any good basic SQL web sites out there? I know all about Access developement and i know some SQL, but i know nothing about SQL server. Which is the best site for me?

I have a situation that I was wondering if anyone has ever ran into before. It has to do with one of my MS SQL servers. The hardware is a ALR/Gateway 9000R with 4 PP200's, 1 Gb RAM, and a RAID 5 with 72 Gb storage. The NIC card is an ATM 155 Mbit card connected directly to our fiber backbone.
I have WinNT 4.0 Server Enterprise Edition loaded with SP4 and MS SQL Server 6.5 Enterprise Edition with SP5 installed.
I have 7 seperate active databases on the server supporting 7 different applications. The server has been on-line for approximately 4 weeks and just recently (last Thursday) it has started to "lock up" every couple of days. By lockup I mean that it starts to reject all requests by all users. No one can connect to the server including myself. The MS SQL error log grows and grows until we reboot the server. The error logs are 100 Mb or larger in size due to rejection errors being repeated over and over again.
There has been no change made to the server since initial installation.
The error in the MS SQL error log that keeps on being repeated is...
"Message 17308: Kernelerror - Lazywriter. Process (process ID number) generated access violation; SQL Server is terminating this process."
We have an incident in with Microsoft but they are not responding fast enough.
I was hoping that someone out there may have had this type of occurrance happen before.
Any suggestions?

Anyway I want to know if there is a way to get SQL Server to release a lock without using the kill command. My reason for asking is because this morning I was investigating some deadlocks and thought it would be nice if SQL Server upon identifying a deadlock instead of killing the victim SPID would simply force the victim SPID to release the lock causing the deadlock so that the other SPID could continue and the victim would simply have to wait longer.That lead me to wonder if there was a T-SQL command or DBCC to force SQL Server to release a lock that I specify.
So, any way to get SQL Server to release a lock without using the kill command?
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
View 12 Replies View RelatedWhen one process has one record locked in Update-Mode then an other process can't update any other records on that table with some queries, other queries that access the same records (but with a different WHERE statement) will execute.
This problem occurs with SQL Server 2005, but it didn't with SQL Server 2000 (or any other database).
The problem:
-Process 1 locks a record in the table, and keeps it in Update-Mode, because the user is editing it. (Using OLEDB Pessimistic Cursor-locking)
-Process 2 wants to update an other record, buts gets a "Lock timeout" when using one query but not with another.
For example this query will work :
UPDATE gwseqnumber SET nextseqnr = 3 WHERE row_id = 110;
But this qeury will give me a "Lock timeout" :
UPDATE gwseqnumber SET nextseqnr = 3 WHERE name = 'REC_2';
But it is the same record!!
The record with name = 'REC_2' has the row_id = 110, both values are unique in the table.
The data:
The table [gwseqnumber] has the following CREATE statement:
CREATE TABLE GWSEQNUMBER
(
NEXTSEQNR INTEGER,
NAME CHAR (20),
ADMINISTRATIONCODE INTEGER,
FINDHIGHESTNUMBER CHAR (1),
CLOSEDYN CHAR (1),
ROW_ID INT IDENTITY(1,1) NOT NULL
);
CREATE INDEX KEY_1 ON GWSEQNUMBER (NEXTSEQNR);
CREATE UNIQUE KEY_2 ON GWSEQNUMBER (ADMINISTRATIONCODE, NAME, IDENTIFIER);
CREATE UNIQUE INDEX KEY_3 ON GWSEQNUMBER (ROW_ID);
Both KEY_2 and KEY_3 are unique, KEY_1 is not.
If I remove the index on the NEXTSEQNR column (the index named KEY_1) then both these queries will work, so it is obviously related to the index.
Altough the index is obsolete and can be removed from this table, it should not result in bogus locking errors.
Even when i removed the index not all the queries will work. (With work i mean not run into a locking error, while the record is not even locked.)
Solutions tried:
- Set the compaitiblity level of the databsae back to 80 (for SQL Server 2000 compatibility).
- I have already tried to disable Page-Locking on all the indexes of this table.
So why does the index lock my updates in SQL Server 2005?
And how do i fix it so my database does not run into these locks?
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.

Haroon
