Can Get Server To Release A Lock Without Using Kill Command
Aug 26, 2015
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?

The former programmer wrote this stored procedure. It haven't been run for a while, so I was given the assignment to get it working. When I ran the stored procedure, it took almost 9 hours. Then I found that I can't access a few tables, so my guess it there is some issues with table locking. The stored procedure use this...
Code:
BEGIN TRAN
--blah blah
COMMIT TRAN
ERROR_HANDLER:
ROLLBACK TRAN
Obviously there seem to be a logic error in the middle of the script while running the stored procedure. So, how do I cancel the transaction and unlock the table? I'm unable to access the few tables.
Also, does rebooting the computer helped to release the transaction or table locking?
Thanks...

BOL say to kill a process use (i.e. Kill 10).
I am trying to get the kill command to accept a variable
declare @aProcess smallint
set @aProcess = 30
kill @aProcess
On the above code I get the following syntax error.
Server: Msg 170, Level 15, State 1, Line 3
Line 3: Incorrect syntax near '@aProcess'.
Any suggestions, ideas, etc. would be Appreciated!!
Thanks.

I am in the process of writing a stored procedure that takes data from a table, within a cursor, and puts that data to the network server via the xp_cmdshell procedure. The xp_cmdshell command is at the end of the cursor in the SP.
I have worked with the admins on getting the proper permissions to execute this procedure and have tested it by running the procedure directly in Query Analyzer and by calling it in Query Analyzer successfully.
However when I try to call this procedure from another programming envirnoment, once the xp_cmdshell process is called, the procedure locks up and blocks the rest of the process, including the other software programming environment. When I look at the error log, it indicates that correct command, as a matter of fact I have copied the log file command into Query Analyzer and ran the procedure successfully. So for some reason, the statement is not being committed or there is some kind of threading issue I do not know how to address.
If anyone out there has any suggestions or has a simular problem in the past and knows how to address it, it would be greatly appreciated.
Thanks!

Do you know of a way, in the OLE DB Command (Executing a sql command for each record), to specify a lock hint?
Example: in my component, I want to update a table but I want to specify a ROWLOCK or UPDLOCK hint.
When I try using this sql statement in the 'SqlCommand' property:
UPDATE DIM_Accounts WITH (UPDLOCK)
SET COL1 = ''
SSIS gives a syntax error.
Do you know any workarounds?
Thanks!

I'm trying to kill a bunch of processes in SQL 6.5 and I can't. I'm running the only machine with SQL tools installed on it (the server) and it won't let me kill them. I try the GUI screens and the Kill statement in ISQL_w. Is there any way around this?
I've stopped the SQL Server and rebooted the NT Server. Is there anyway I can get rid of these processes. They are locking some tables and keeping me from inserting data within my code. Very frustrating.
Thanks

Hi,I am having an issue with SQL server that slows everything to a crawl,and makes almost any query impossible to complete.Here are the symptoms:I stop SQL, I start SQL. The task manager shows SQL starting up andquickly allocates 50 MB of memory. I then open SQL Manager and I canopen up the instance of SQL Server and I expand to see all of thedatabases, memory rises to about 70MB allocated. I then expand adatabase and view a list of tables. The memory allocation quicklyrockets to 860+ MB and any attempt to query they database results inhuge hang times.I have MacAfee anti-virus in place and it is constantly scanning forviruses, so I don't think it is a virus. The log files do not appearto be large. I have done everything I know to do to resolve this. Anyhelp would be much appreciated.Does anyone have any ideas?Thank you for taking the time to read this.Tod

Hi all,
does anybody know when SQL Server 2005 Service Pack 3 will be released?
We are currently encountering a lot of problems with replication. We have seen that the different SP2 Cumulative Updates are fixing a lot of replication troubles... but as they are not fully tested, we do not want to install them on our production servers.
Thanks in advance!

I simply made my script task (or any other task) fail
In my package error handler i have a Exec SQL task - for Stored Proc

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

Hi!
I have a small problem , but it's still a problem.
I have a SQL Server Agent job that runs a .cmd file. This CMD is logged to a textfile.
This process is locked, waiting for me to type a password, but I have nowhere to type that pass.
What I want to do is kill the process that i locking the logfile, because since the logfile is locked, the job cannot be started again (and it's a scheduled job).
The jobs status is 'Not Running'.
I have solved the problem by making the cmd write to another logfile, so the schedule will work, but the file is still locked, and I don't want to restart the server since it's a productionserver.
How to I find the process that is initialized from SQL Agent, and kill it?
Thanks!

I downloaded SQL Server 2008 Release Candidate (Express) Beta on 6/16/08. Installation started but failed. A message stated Microsoft NET Framework 2.0 SP2 needs to be installed first.
I downloaded SP2 and installed it. However, when I try again to install the SQL 2008 Release Candidate Beta I get the same message that SP2 must first be installed.
Can someone tell me how to make the SQL Beta version installer recognize the previously installed SP2 Service Pack?

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.

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

My objective is to use Enterprise Manager to move (copy) my SQL db from the server to my windows desktop computer.
I downloaded MSDE and am having trouble installing it, no doubt because I do not understand the documentaion (ReadMeMSDE2000A.htm).
When I try to run setup, I get that message that says:
"A strong SA password is required for security reasons. Please use SAPWD switch to supply the same."
Considering my purpose, do I need a "strong" SA password? If not, how do I get around it? If yes, how do I set it up?
I am a Mac user so I have poor windows skills, please make it as painless as possible for me, 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.
cheers,

Hi,
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
