DB Engine :: Max Value Of Maxtransfersize And Buffercount Adjustment VS Physical Memory On Box
Aug 5, 2015
Eager to know to set the Max Value of Maxtransfersize and Buffercount adjustment but also anxious to know Physical memory impact.URL...The max size that can be used is the (Buffer Pool’s To Physical Memory / 16). As returned from the GlobalMemoryStatusEx (ullTotalPhys ) API call. HereBob dorr saysBuffer Pool’s To Physical Memory/16 what it means? (ie. Buffer Pool/ Physical memory/16.0 or (Physical Memory - buffer pool)/16

We have Windows Server 2008R2 installed on VM Server.On that we have three SQL instances running. From few past months we are observing physical memory is going high. Earlier we observed it was at 86-88%, now it is 96-97%.We have 16RAM & 8 CPU cores on VM. what is the best and ideal configuration so that we can rectify the high physical memory issue.

Environment: Win2003 SP1, 32 bit, SQL Server 2K5
My server has 16GB RM but it is using only 3GB. And I see my server is using 3GB of Virtual Memory, too. Why my physical memory is not being utilized? How can I increase Physical Memory usage and decrease VM usage?

We have a sql 2005 server with 8GB of RAM. Task Manager shows that it only has 198,250k (about 200 MB) of Physical Memory available. I wonder if that number should be higher.
What can I check (Perfmon counters? Which ones?) to indicate it that's too little RAM, the right amount, or too much.
Thanks,

We are currently running a server with standard edition Windows Server 2003 R2 with standard edition SQL Server 2005 SP2.
The server has 4GB of memory of which 3GB is dedicated to SQL and 1GB to the OS via the use of the /3GB switch.
If we were to increase the physical memory to 12GB (and carve out 2GB for the OS and 10GB for SQL) would we have to upgrade the OS to Enterprise version to access the additional 8GB of memory we plan to add?
Thanks ALL!

I am trying to attach a database to SQL 2005. This database has not previously been attached. I have only just installed SQL.
I get the following message: Unable to open physical file "C:ArrowSQLArr@DataArrow_data.mdf" Operating system error 5: "5(error not found)" (Microsoft SQL Server: Error 5120)".
I have loaded SQL and the database fiel and directory with the same user account which is a local administrator on this machine. I have checked that I have read/write access to the file.
The machine runs Windows Vista Business. SQL has SP 2 loaded. What causes this?

We have a new set up on VM to run an application running 24*7 (migrated from SQL server 2008R2) with below configs:
1. OS- Windows server 2012 Standard 64 bit hosted on Virtual Machine
2. Memory 16 GB and Cores =4 with 2.4GhZ processor
3. SQL server 2012 SP2 , 64 bit Standard edition.
4. Total size of databases as of now 15 GB with biggest being 5 GB.
How should i go around in setting the MAX and MIN server memory settings. I have this set up for many of SQL 2005 and 2008R2 servers, but for 2012 i heard that things has slightly changed.
How should i start analyzing and setting the right value of this MAX and MIN?

One server, a part of a 2 node always on cluster, had problems, I had to restart.
I'm getting this error for example now:
Error: 49910, Severity: 10, State: 1. (Params:). The error is printed in terse mode because there was error during formatting. Tracing, ETW, notifications etc are skipped.
+
SQL Server was unable to run a new system task, either because there is insufficient memory or the number of configured sessions exceeds the maximum allowed in the server. Verify that the server has adequate memory. Use sp_configure with option 'user connections' to check the maximum number of user connections allowed. Use sys.dm_exec_sessions to check the current number of sessions, including user processes.
Now, on the instance I have activated maximum servere memory, my question; Is it possible to adjust this setting without starting the service?
Some parameter for example?
The server itself have enough memory.

If I create a memory table inside a while loop, I expect that every loop the memory table is (newly) created and thus empty.
But when I test this, I see that on the second, third, ... run the inserted data in the memory table is still present and not cleared.
This can be reproduces with the following code:
DECLARE @tbl TABLE
( [id] BIGINT )
DECLARE @tbl2 TABLE
( [value] BIGINT )
INSERT INTO @tbl
VALUES (1), (2)
[Code] ....
/*
Expectation: twice 11 and 12 in @tbl2
Actual result: three times 11 and 12
*/
SELECT *
FROM @tbl2
Is this a wrong assumption or is this a bug in SQL Server? (Tested on: SQL Server 2014 and 2008).

On first Node A: The server has 16 GB of physical RAM.
On second Node B: The server has 10 GB of physical RAM.
Now, this being Active Active, Node A can be clustered on failure onto Node B..Now reporting server is configured under these two nodes, with defined MAX and MIN server memory of 12 as MAX and 0 is min IN GB.Now with this setting on SQL whenever the cluster moves, such config make OS goes low on node for 10 GB.I am only left with option of switching this MAX and MIN to a default setting or is there any other alternative such as script which can change this setting accordingly when cluster moves to respective server.

In SQL Server 2014, how big for the block size is better for performance? 64 KB? 4 KB?
For normal database files, best practise is 64 KB disk block size. Not sure if it is same for memory-optimized filegroup.

I am using Visual Web Developer 2005 Express Edition & SQL Server 2005 Express Edition.
In a database that is role-manager-enabled, you will have some tables like apsnet_Users, aspnet_Roles, etc.
And some Columns like CreatedDate, LastLoginDate in the tables.
My problem:
The datatime values in the aforementioned fields are updated based on GMT instead of the client's local time zone.
Is this the way it is?
No matter true or not, how to fix it?
Many Thanks in advance :)

Hi, everyone!
I faced the problem trying to adjust ssl encryption in ms sql server 2005.
I've completed all steps from this article:
http://msdn2.microsoft.com/en-us/library/ms191192.aspx
But when I'm trying to restart sql server - it fails to start.
Here the error messages I got:
1. Unable to load user-specified certificate. The server will not accept a connection. You should verify that the certificate is correctly installed. See "Configuring Certificate for Use by SSL" in Books Online.
2. TDSSNIClient initialization failed with error 0x80092004, status code 0x80.
3. TDSSNIClient initialization failed with error 0x80092004, status code 0x1.
4. Could not start the network library because of an internal error in the network library. To determine the cause, review the errors immediately preceding this one in the error log.
5. SQL Server could not spawn FRunCM thread. Check the SQL Server error log and the Windows event logs for information about possible related problems.
SQL Server is installed on Windows 2003 Server OS running computer.
I use certificate created by means stand-alone Certificate Authority that appeared in Administration Tools on that computer after I installed Certificate Services.
I guess the reason is in wrong certificate parameters I set while requesting.
How can I determine correct certificate parameters? Does anyone know?
Any help is appreciated,
Thanks

I am looking to test this feature - and the "Transaction Performance Collector" has recommended me a table to port to In-Memory OLTP.
I have now tried the "Table Memory Optimization Advisor" tool.
After a couple of tweaks to the table design - the tool is now passing validation but the tool is not allowing to progress to the next step:
Could it be down to not having enough memory? But would this not show in the advisor?

I'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.

Hello, 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?
Thanks,
fshguo.

I am running Visual Studio 2005. I have an SSIS Package which is consuming a huge amount of memory. During the execution of the package the memory keeps increasing. 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?
Thanks! Aaron B.

sql 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
