AWE/Lock Page In Memory Drawbacks? Min/Max Settings, Memory Issues
Oct 11, 2007I've been researching AWE to determine if we should enable this for our environment.
Currently we have a quad core box with 4 gb of RAM (VMware). OS: Windows 2003 std, SQL Server 2005 std. 3GB is not set but will be as soon as we can perform maintenance on the server.
I have read mixed feedback on AWE, either it works great or grinds you to a hault. I would assume that the grinding to a hault is due to not setting the min/max values correctly or not enabling the lock page in memory setting.
We only have one instance of SQL on the server and this box won't be used for anything else aside from hosting SQL services. We do plan on running SSRS off of this server as well.
1. Will running SSRS and enabling AWE cause me problems? Will I have to reduce the max setting by the SSRS memory usage or will it share and play nice?
2. How do I go about setting the Max value? Should it be less than the physical RAM in the box? Right now its set to the default of 214748364, even if I don't enable AWE should this default value be changed?
3. It seems that even at idle the SQL server holds a lot of memory and the page file grows. If I restart the process in the morning, memory usage in taskmon is at 600mb or so. By the end of the day, its up around 2gb. How can I track down whats causing this, should this even concern me?
4. The lock Page in memory setting worries me. Everything I've read on this seems to give a warning about serious OS and other program support degradation. In some cases to the point where they have to restore the settings on the server before they can bring it back up. What are your thoughts on this.
Row 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.

Will AWE Work If Lock Memory Pages Not Set
May 8, 2002I have a remote site/SQL 2000 box that is not under our control. We have SQL 2000 Ent Edition up on a Win2000 box that has 8 gig of memory. We think their NT person setup the SQLExec account to have this right to Lock memory pages, but having trouble verifying this. AWE was enabled on SQL Server and has a max memory setting of 6 gig. It shows AWE enabled in the SQL error log. The box only has had a few users (and in some case only running perfmon) but has locked up on several occasions. Nothing in either WIn2000 log or SQL to show why. MY question after stating all these facts is that if we have AWE enabled,(and the boot.ini file is correct per Microsoft Specs) will AWE come up if the SQLExec does not have these rights. And if he doesn't have these rights could it come up and crash unexplained like this.
View 1 Replies View RelatedLock Pages In Memory On X64 Standard
May 18, 2007All,
I have a new database server running W2K3/MSSQL2K5 x64. I read in BOL that you can use the Lock Pages in Memory option to improve performance on your database server. I did some research on the internet and some sources are stating that you can only use that option with MSSQL2K5 Enterprise but in BOL they state that you can use this option in Standard/Enterprise.
Can anyone confirm that "Lock Pages in Memory on x64 Standard" works in MSSQL2K5 Standard?
Thanks in advance for the 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!

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
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

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
I Need To Pass Data Entered /created On The First Page To The Next Page And Populate The Next Page With Some Data From The Fir
Nov 28, 2006Hello I have a project that uses a large number of MS Data access pages created in Access 2003 and runs on MS SQL2005.
When I am on lets say my client, (first page in a series) data access page and I have completed the fields in the (DAP), I am directing my users to the next step of the registration process by means of a hyperlink to another Data access page in the same web but in a linked or sometimes different table.
I need to pass data entered /created on the first page to the next page and populate the next page with some data from the first page / table. (like staying on the client name and ID when i go to the next page)
I also need the first data access page to open and display a blank or new record. Not an existing record. I will also be looking to creata a drop down box as a record selector.
Any pointers in the right direction would be appreciated.
I am some what new to data access pages so a walk through would be nice but anything you got is welcome. Thanks Peter€¦

View 10 Replies View RelatedWould Max Memory Including SSIS And SSAS Memory
Mar 27, 2008Hello, I understand that we should use SSMS -> Server Properties -> Memory to put a cap on the SQL server memory usage, therefore it gives some space memory for OS, this is based on the fact if the max memory is not specified, SQL will use whatever available memory and eventually crash the system.
My question is that when a server has SSIS and SSAS services installed along with the SQL service. Would the max memory setting covers the SSIS and SSAS memory usage, or the SSIS and SSAS has to shared the memory with OS?

Memory Issues, SSIS Package Out Of Memory Help

Until finally i get an Out of Memory exception. I have run this package using dtexec, and in the BIDS. No difference. I do have some script components and have added some code to get the assemblies in the current appdomain. I do see that one particular assembly is increasing on every loop. VBAssembly every time it hits the script component is increasing by 6, and along with it the memory is climbing. What is this VBAssembly being used for is there an update to SQL Server Integration Services that I need?

Sql Server 2000 Using Less Memory After More Memory Added
Aug 22, 2007sql server 2000 is running on windows server 2003 ... 4gb of memory on server .... 2003 was allocated 2.3gb nd sql server was allocated (and using all of it) 1.6gb for total of approx 4gb based on idera monitor software ... all memory allocated betweeen the OS and sql server .... then 4 more gb of memory added for total now of 8g ... now idera monitor shows 1.7gb for OS and 1.0 gb for sql server ..... 'system' info shows 8gb memory with PAE ... so I assume that the full 8gb can now be addressed .... why are less resources being used now with more total memory .... especially sql server ..... i thought about specifying a minimum memmry for sql server but i amnot convinced that would even work since it seems that this 1gb limit is artificial .... it it used 1.6 gb before why would it not use at least that much now ??
thank you

I can't find any explanation why is it string1 and string 2 of the footer section of my report displayed separately from the expression3 which is aligned on it and the rest of the object on the second page.
The expected design is that all Footer items should be displayed together of whether it is placed on the first page or on the last page.
As a workaround of this, I converted string 1 into an expression (Added = and enclosed the string with double quote).. As a result, all of the items in the Footer section are now placed together on the last page of the report.
I also remember one of the issue I encountered before where the Footer items where placed together on the first page and still have space at the bottom of the page, but then expression 6 is forced to display (alone) on the last page of my report.
I can't find any discussion related to this, I wish somebody could give me an idea why RS behaved like this.

Local - Including Page Header Forces Viewer To Expand To Page Size
Jul 17, 2007Hello,
If I have a report that includes a page header, the report viewer will render the report at the full width, but if I hide the page header and show only the body it will use the absolute width of the report.
I have a 7" wide report, with .75" borders set on each side.
Interactive & Print size are set to 8.5x11
Changing these sizes has no effect on the behavior of the viewer, which appears to ignore them.
When I view this report in the local viewer the contents fill the window if there is no page header.
If I enable the page header then the report is drawn at 8.5" wide, leaving a _big_ white border on the right side.
Any comments or workarounds that anyone knows? I know the local viewer is not a standard configuration (at least it seems) but it is what we need to use.Thanks,//Andrew
