I've got a Windows 2003 Enterprise server with 8GB of memory running
SQL 2005 Standard (32 bit). According to the documentation SQL can
take up to the OS maximum amount of memory (64 GB with PAE). Well,
SQL isn't taking more than about 1.5GB of memory, and the Buffer Cache
Hit Ratio is up close to 100. How can I make SQL use more physical
memory?
Thanks
DylanIf the Buffer Cache Hit Ratio is 100, that means that SQL Server doesn't
need to take any more memory. Your queries are all using data that's
already cached. SQL Server will not take memory it doesn't need.

Ah, so you're right - I was reading my thresholds sheet wrong. I guess
I should have thought about what a ratio is before posting.
In any event, this SQL server's not very highly utilized right now.
If it becomes more highly utilized and does in fact need to take more
memory, will it, or do I need to change anything? I was reading about
enabling AWE - is that something that I should have enabled?
Thanks!

Yes, you'll have to enable AWE if you want SQL Server to use any RAM
over the 2GB user-mode VAS limit.

Great, thanks - one last question. I see that you need to enable Lock
Pages in Memory access through group Policy. It says to:
In the Select Users or Groups dialog box, add an account with
privileges to run sqlservr.exe.
Is that referring to the user that the MSSQLSERVER service logs in as
when it starts, or is that just any user with login access to the
database? It seems like no matter what account (or accounts) I give
that access to, SQL still spits out an error saying that they don't
have access.|||"dylan" <dylan.roehrig@.gmail.com> wrote in message

AWE is needed for 32-bit SQL Server, whether running on a 32-bit or
64-bit operating system. Lock Pages in Memory is only needed for 64-bit SQL
Server. You're running 32-bit SQL Server, according to your first post?

I really need to read these things better, I didn't see in your
previous post that you were talking about Enterprise Edition SQL
Server, I thought you meant 64 Bit Windows 2003 Enterprise Edition.
Yes, I am running 32 bit SQL Server Standard on 32 Bit Windows 2003
Enterprise. Given that, I can't get AWE to enable. When I try to
enable it, I get the following error:
Alter Failed (Microsoft.SQLServer.SMO)
Additional information
+ An exception occured while executing a Transact-SQL statement or
batch.
(Microsoft.SQLServer.ConnectionInfo)
+ Address Windowing Extensions (AWE) requires the "lock pages in
memory" privilege which is not currently present in the access token
of the process.
When I looked that up, I found that I needed to enable the Enable the
Lock Pages in Memory Option. Using this article
http://msdn2.microsoft.com/en-us/library/ms190730(SQL.90).aspx I tried
to do that, but it is still not working. Any insight?
Thanks very much for your help.|||Do you have the /PAE switch enabled in boot.ini ?

Well, that's part of the issue, I guess. It says "add an account with

No, that shouldn't be an issue. Did you try rebooting? I'm wondering
if the policy isn't being applied for some reason.
Also, if you look in Task Manager, is SQL Server running using the
account that you think it should be using?

I haven't tried rebooting, I can't do that until tonight, but I will
try that. I know sometimes Computer Configuration policies do not
take effect until after rebooting. I checked, and the SQL Server is
running as the account I expect it to be.|||Do you see "Address Windowing Extensions enabled" in the message log?
