Table Lock Option Clarification
May 5, 2008Does the Table Lock option in the OLE DB Destination task in a data flow refer to a lock on the destination table or on the source table from which the table is loading from?
The reason I ask is because I have a package run twice simultaneously pulling from the same server and table onto two different tables on two different servers. When I kick off my job to run the two data pulls, one of the jobs terminates with a
"TCP Provider: An existing connection was forcibly closed by the remote host." message. I believe this is due to a table lock on the server, but can't figure this out.
Thanks in advance for your help.
Lock Pages In Memory Option On SQL 2005 STD 64-bit With W2K3 R2 Standard 64-bit - Does It Work?
Nov 9, 2007 Hey Folks -
I'm setting up a new production SQL 2005 64-bit server running on a dedicated Windows 2003 R2 Standard system w/8GB of RAM.
I've enabled the "Lock Pages in Memory" option (http://msdn2.microsoft.com/en-us/library/ms190730.aspx) but when I run dbcc memorystatus all of my AWE counters show 0.
According to http://blogs.msdn.com/sqlprogrammability/:
"On 64 bit machines, execute 'dbcc memorystatus'. If the AWE Allocated memory is 0 then lock pages in memory privilege has not been granted to the service account or it has not taken effect. "
Does the "Lock Pages in Memory" option work on W2K3 R2 Standard? Just searching across the web I find different answers. In some places it clearly says that Lock Pages in Memory only works on W2K3 Enterprise systems. In other places it says that it should work on any Windows 2003 64-bit OS.
Does anyone have any ideas? Assuming we cannot "lock pages in memory" due to the Windows 2003 Standard OS, are there any other memory management recommendations out there?
thanks!
Error: A Deadlock Was Detected While Trying To Lock Variable X For Read Access. A Lock Could Not Be Acquired After 16 Attempts

In SqlServer Management Studio Express, Server Type Option Is Greyed Out, Also Publication Option Missing
Apr 27, 2008Hi everyone In my SqlServer Management Studio Express, on start up it shows the server type option, but greyed.So that value is fixed to database engine. ( I'm trying to work on an SqlServer Compact Edition database through the SSMStudiothat's why I'm trying to get this to change.)Besides, after I connect i go to the Object Explorer, expand the server node, and go to Replication.When i expand replication, i get the "Local Subscription" option, but nothng for Publication.( I want to work on Merge Replication, that's why I desparately need Publication to work)Am i missing something here? I did not install SqlServer separately, I only have what comes bundled with the Visual Studio 2005 Setup.
View 2 Replies View RelatedRow Lock Versus Page Lock In SQL 2000.
Apr 7, 2004Hi
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.

ERROR: A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List.
May 22, 2006Hi,
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.
A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List
May 10, 2006Hi 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

SQL 2012 :: Configuring Memory Per Query Option And Index Create Memory Option
Feb 10, 2015So I started a new job recently and have noticed a few strange configurations. Typically I would never mess with min memory per query option and index create memory option configuration because i just haven't seen any need to. My typical thought is that if it isn't broke... They have been modified on every single server in my environment.
From Books Online:
• This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician.
• The index create memory option is self-configuring and usually works without requiring adjustment. However, if you experience difficulties creating indexes, consider increasing the value of this option from its run value.
How To Lock A Table So Others Cannot Lock It
May 23, 2001Hi,
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

Mar 27, 2001Hello,
An application we are designing is behaving rather strangely. Basically, we
have a trigger on SQL 2000 on W2K Server watching for a record update. When
that happens a stored procedure gets executed which in turn spawns a VB that extracts that record, applies some rules to it, and writes a text file to disk. 9 out of 10 times, this program will cause a CPU spin, and it can't be killed from the Task Manager.
I did not write the VB app, I am writing the front end for the application in ColdFusion, but I need some ideas on what might be causing such behavior and how can the problem can be diagnosed. Thanks for any help!

DB Lock-up??!!
Mar 29, 2007Hello,
Wondering if anyone might have a guess about this.
I have a small 4 table DB. it's got several stored proc's and it's accessed through .NET to fill it in and get data from it.
It's been working just fine. But this morning, while it was doing its thing, I experimented with it by adding then deleting a View (through the View Wizard.)
Then later I started noticing that my .Net calls had slowed to a crawl (I hadn't made any code changes)and even making direct queries through Query Analyzer had slowed too.
My question is: being that there were no network issues, could the View create/delete have caused the DB to come to a halt or perhaps a table lock-up?
While I'm at it, is there anything that I can put in stored proc's or other places to prevent locking issues (if that's what happened here.)
I already use Begin/Commit Tran pairs.
And sorry if this post doesn't read like a SQL beginner, but believe me, I am.
Thanks for your advice!!

No Lock
Aug 20, 2007Lets say i have a view.
vuTestingNoLocks
this view looks like this...
Create View vuTestingNoLocks as
SElect *
From dbo.Employees
inner Join dbo.EmployeeTerritories on EmployeeTerritories.EmployeeID = Employees.EmployeeID
If I select from this view using Select * From vuTestingNoLocks (NOLOCK)
Does the (nolock) command propegate down through the tables? Meaning will it scan tables that are locked still ignoring their locks?
How To Lock Out Everyone But Me?
Oct 13, 2006I'm working with SQL Server Express, and I want to configure a named instance so that only the 'sa' user and a specified SQL Server user with a specified password have access. In particular, I'm trying to lock out BUILTINAdministrators. Furthermore, I need to be able to do this from a command-line, since I want to configure it in a script. Nothing I do seems to work.
I've attempted to use sqlcmd and the T-SQL call ALTER LOGIN [BUILTINAdministrators] DISABLE, but that returns the error "Cannot alter the login 'BUILTINAdministrators' because it does not exist or you do not have permission."
What I can (apparently) successfully do is run DENY CONTROL TO [BUILTINAdministrators]. This runs without reporting an error. However, after running it against the 'master' database and the specific database in my named instance I care about, I can still run the following:
sqlcmd -S (local)MyInstance -d MyDB -Q "select * from my_table"
and see the contents of my_table.
What do I need to do to restrict access exclusively to 'sa' and other SQL users I designate?

Lock Quesiont
Apr 26, 2000With the Oracle RDBMS, readers never wait for writers and writers never wait
for readers. If a SELECT
starts reading at 9:01 and encounters a row that was updated (by another
session) at 9:02, Oracle
reaches into a rollback segment and digs up the pre-update value for the
SELECT. A transaction does
not need to take locks unless it is modifying a table and, even then, only
takes locks on the specific
rows that are to be modified.
How does MS SQL Server 7.0 handle this problem? Thanks for any info or

This is a sql 2000 server running on Win 2003 with 16 gig of RAM on a new Dell quad box with data on a SAN. That's the good news. The bad news it is a 3rd party app which I have almost no ability to change. The users connect through Citrix with about 400 concurrent at a time. I was looking at setting a higher min lock issue. yesterday it sent me the dreaded alert Fatal error in resources with this issue and buried the server at 100 CPU for about 2 minutes. Any help or insight appreciated. Most of my standard sql data looks OK, Cache at about 99, system queue at about .8.
