SQL-Server Memory Consumption
Mar 9, 2005
Hi,
I've thre problem that our MSDE SQL-Server 2000 (without SP3) memory consumption is constantly increasing. Even though, that I limitet the 'max server memory' with sp_configure and RECONFIGURE it's growing above that limit.
When I shut down the application, SQL server does not free the memory. I was already checking the database file size (transaction logs) and made shure that autoshrinking is enabled.
Does anybody have an idea, why SQL-Server does not release the memory?
Thanks for support, rene

Hello!
We have a SQL Server 2000 that has been working nice
without any issues. Lately we noticed the fact that the amount of memory that
it is using has increased and once it took down the web server as the total
amount of memory used was 2G. Due to this fact I have set Memory Max to 500MB.
Now as I look in Task Manager the Memory usage is at 530396k which is 518MB.
Any reason why would it exceed the 500MB?
What we did before was to stop the SQL Server and restart it, and it takes about
2 days until it gets back to +500MB.
What can I do to stop this behavior?
Thanks.

I've been working on serveral packages for the past hour and after finishing for the night I quickly wanted to check to see how much memory SQL Server was consuming on my laptop. It was using almost 500MB of memory. It typically hovers around 50-100MB when I'm not doing anything with it. Is this normal?

Hi all,
I have two database server, named it DB_A and DB_B. I want to establish a linked server of DB_A in my DB_B. There's a script in DB_B that queries data from DB_A but only execute periodically. Does linked server consume large memory or CPU when it didn't use ?
Thanks in advance,
Hery

I know I can run DBCC MEMORYSTATUS to view how much memory SQL Server is using on a 64-bit server, but how do I view how much memory the other processes are consuming?
I do not believe the Perfmon counters are accurate when using AWE or 64-bit memory, at least in terms of memory consumption per process so how do we see this information. I have a feeling it is not possible.
Here is the problem. We have a 64-bit server with 32GB of memory. SQL Server is configured to use no more the 20GB. It currently is using only 15GB. The O/S is reporting 28.3GB used out of 32GB, which means some other processes are consuming 28.3GB - 15GB = 13.3GB. How can I determine what is using the 13.3GB of memory?
Thanks, Dave

Hi to all, on our project we are facing this problem: our users using report builder are making reports containing several Mb of data (sometimes also 1Gb!). Now it happens that when 3-4 users do a report like that on the server the process w3wp.exe reaches also 10 Gb of memory allocated and then the whole reporting services istance stops working.
We want to limit the number of rows that can be extracted from the sql server db using report builder. In the report model reference seems that there is not this kind of option (something like "max rowcount"). Is it possible to set this limit to the user that connects to sql server (something like: whatever is the query this user does, set @@rowcount to 10000)?
Thanks.
Alberto.

Hi there,
I have a large XML document (100Mg) that I want to process through a data
flow process.
Part of the process is to Sort the various relational tables created by the XML Source - then merge join them.
The Sorts consume all the available memory and the process grinds to a halt.
However, if I source the same data from SQL tables, the sorts don't consume anywhere near as much memory.
So a couple of questions:
1. Is there a difference between the way SSIS sorts XML Source Data and the way it sorts OLE DB Source Data?
2. Are there any techniques/best practices when dealing with large XML Files?
Thanks,
Dave.

When Running the standard Memory Consumption Report in the section Buffer Pages Distribution (# Pages) i get the following error
Unable to retrieve data for this section of the report. Following error occurred. Msg 8114, Level 16, State 1 Error converting data type bigint to int.
Any Ideas

Hi
I did a load testing and found the following observations:
1. The Memory:Pages/sec was crossing the limit beyond 20.
2. The Target Server Memory was always greater than Total Server Memory
Seeing the above data it seems to be memory pressure. But I found that AvailableMemory was always above 200 MB. Also Buffer Cache HitRatio was close to 99.99. What could be the reason for the above behavior?

Hi,
I have a webservice, which I am using in the Web service Task. The XML response, is fed to the XML source and I want to write the data from this XML to flat file. I am using the below attached schema definition for XML (.XSD). When I use this as XSD in the XML source task, in the column definition I see only three columns and they are
ZoneCode
ZoneName
AggregatedCZ_Id
My question is what is AggregatedCZ_Id and why I do not see the PostCode in the columns? Any help is appreciated.

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

We are planning a shared SQL Server 2005 enviroment where users can create databases/applications for themselves and/or departments. With the consideration that there can be multiple SQL Servers on a box, can each instance limit a user's disk space? Thanks for any enlightenment.

Hi all, what's the recommended way of passing a parameter than can be consumed properly by a SQL statement using the IN keyword.
For Example:
proc Test @Param varchar(200)
as
begin
SELECT FieldA, FieldB
FROM TABLE
WHERE FieldA IN (@Param)
end
An option is making the query into a string
strSQL = "SELECT FieldA, FieldB FROM TABLE WHERE FieldA IN (" + @Param ")"
then executing the string, but I was wondering if there is a more effective way?
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.

My server is a dual AMD x64 2.19 GHz with 8 GB RAM running under Windows Server 2003 Enterprise Edition with service pack 1 installed. We have SQL 2000 32-bit Enterprise installed in the default instance. AWE is enabled using Dynamically configured SQL Server memory with 6215 MB minimum memory and 6656 maximum memory settings.
I have now installed, side-by-side, SQL Server 2005 Enterprise Edition in a separate named instance. Everything is running fine but I believe SQL Server2005 could run faster and need to ensure I am giving it plenty of resources. I realize AWE is not needed with SQL Server 2005 and I have seen suggestions to grant the SQL Server account the 'lock pages in memory' rights. This box only runs the SQL 2000 and SQL 2005 server databases and I would like to ensure, if possible, that each is splitting the available memory equally, at least until we can retire SQL Server 2000 next year. Any suggestions?

Hi,
I am going to install SQL Server 2000 (then SQL 2K5) on a Win Server 2K3 with 8 GB of ram, but it will be 16 GB in the near future.
I would like to reserve a fixed memory (for momemt less than 3-4 GB) for SQL Server and the rest for application (virtualization).
Without AWE enabled, max memory for SQL Server 2K5 is 4GB as for SQL Server 2000?
How can I manage and optimize memory keeping in mind AWE. (any doc, website available?)
Thank

So 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.

Hi all,
I am using StringBuilder to build a huge insert string which clubs around 12,000 insert strings into a single string. But whle executing this string the SQL server does no insert and the profiler shows that SQL server was out of memory. Any ideas?
Is there a limit to the maximum number of inserts I can do?

I just got a new server I need to install SQL Server 6.5 on and am
wondering if someone could give me a little advice as to how much memory
to configure for it. It will be dedicated to SQL Server. It has 1GB of
memory presently with 2- 450Mhz Xion processors. I don't know if you
need any other information to make this decision or not. All the SQL
Server memory charts I see only go up to 512MB of memory.
Does anyone have any suggestions for me? I do realize that this will
have to be fine-tuned depending on the specifics of our server, but any
range to start with will be beneficial.
Thanks!!
Toni E.
