Hi-
We've got an ASP.Net web app that runs off a Microsoft SQL Server
2000 backend. After a few days the SQL server is completely out of
memory and crawls. It looks like there could be some connections that
aren't being closed or something. Is there a good way to figure out
where the problem is. Looking at the current activity in Enterprise
Manager there are a lot of threads sleeping and a few that are
runnable. Any ideas?
Thanks
Hello
We have a problem with MS SQL 2005 Standard on a Windows 2003 x64 Box.
Server MS 2003 Server x64 R2
Quad Core 2.13GHz
Memory: 12 GB
MS Sql 2005 Standard, Sp2
The Sql process uses only 80MB of RAM (from 8 GB) so this machine is very slow. We set the min and max Memory in SQL without success. SQL ist very slow. Has anyone here some hint's to solve this problem? Thank'.

Hi,i am having a strange problem running memory intensive queries on SQLserver.I am doing an update on a table with 9 million records from anothertablewith 50 records.the query i am running isupdate table1set var1 = b.var2from table2 bwhere key1=b.key1this query hanges for ever. I had thought that there was a problem withmy machine...but once out of the blue it ran in 16 minutes.I am running a 1 Ghz PIII with 512 MB of memory.Any ideas as to what could be the issue ?RegardsRishi

Hi..
I'm running a package that has a XML Task in the control flow. This task tranforms a XML file with a XSLT.
The file is about 2 megs on a daily basis, but at the end of the month there is a full dump of data that makes the file to be around 400 megs. There is where my problem is.
I run this on my 2 GB memory workstation and when the memory gauge on the task manager reaches about 1.5gb the package fails with an "Out of memory exception".
I also run this package on a 8GB Ram server, and same applies.
Is there any way of making this package utilize all the available memory, I even increased the virtual memory to see if that helped my issue, but nothing.
Thanks
Fellas!!This is a very complicated one and it took me a few days to figure outexactly what's going on, but here's the final story:I have a production environment running on .NET with a SQL Server(2000, SP3). The SQL Server is on a dedicated Proliant computer with2GB RAM (the actual SQLServer.exe process has dynamic memoryassignment and can reach up to 1.6GB RAM). Nothing else is running onthat specific computer.Once the SQLServer is started, it hits 300MB RAM (the minimum that wasset in the configuration of the server - remember, it is dynamicallyaquired).Then there is a .NET program that requests just about all the data theSQL Server contains (apart from a single table that contains roughly1.6 million rows and another table that contains about 10000 rowswhich are all of type IMAGE).Once all the data is retrieved, the RAM is at about 400MB. From thereon, every update I make to the data on the server causes the RAM to goup by a bit (that updates are done in a Transaction which of course iscommitted at the end). It seems that BLOB updates are the majorproblem in all of this. For some reason, uploading a blob of size 9MBcauses the RAM to go up by roughly 20MB and after commit it gose down10MB (total gain of roughly 10MB RAM). Eventually the SQLServerprocess hits its upper limit (1.6GB) and at this point it startsslowing down.Some performance checks showed me the SQLServer has a lot of diskactivity, it seems it is reading and writing pages of data from/to theHD all the time (which causes the queries to be much much muchslower).We have a development environment running the exact same code (it isthe exact same in everything, except for the amount of data stored inthe DB). This does not happen there at all.I have a few questions:1. Why is the RAM going up after BLOB updates?2. Why is the RAM going up at all?3. How can I tell the DB which tables should remain in the RAM at alltime (never swapped back to the HD?) - DBCC PINTABLE does not seem todo the job.It does not seem to have anything to do with the .NET code.Thank you very much,M Yamo.

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.
I have a Windows sever 2012 with sql server 2012 enterprise. Ram size is 22GB. Sometimes SQL sever takes 95% memory.My question, How to reduce memory size without killing any process because it's production server.So there are many background process is running. And,Is there any guides to learn why Memory is raise d so high and how to reduce it.
View 10 Replies View RelatedHello, 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,

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

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?

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.
Hello frnds Can Anybody explai what does it mean by question itself and how to resole it ?

If I start a long running query running on a background thread is there a way to abort the query so that it does not continue running on SQL server?
The query would be running on SQL Server 2005 from a Windows form application using the Background worker component. So the query would have been started from the background workers DoWork event using ado.net. If the user clicks an abort button in the UI I would want the query to die so that it does not continue to use sql server resources.
Is there a way to do this?
Thanks
One of my stored procs, taking one parameter, is running about 2+ minutes. But if I run the same script in the stored proc with the same parameter hardcoded, the query only runs in a couple of seconds. The execution plans are different as well. Any reason why this could happen? TIA.

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 3 questions about memory based bulk copy.
1. What is the limitation count of IRowsetFastLoad::InsertRow() method before IRowsetFastLoad::Commit(true)?
For example, how much insert row at below sample?(the max value of nCount)
for(i=0 ; i<nCount ; i++)
{
pIFastLoad->InsertRow(hAccessor, (void*)(&BulkData));
}
2. In above code sample, isn't there method of inserting prepared array at once directly(BulkData array, not for loop)
3. In OLE DB memory based bulk copy, what is the equivalent of below's T-SQL bulk copy option ?
BULK INSERT database_name.schema_name.table_name FROM 'data_file' WITH (ROWS_PER_BATCH = rows_per_batch, TABLOCK);
-------------------------------------------------------
My solution is like this. Is it correct?
// CoCreateInstance(...);
// Data source
// Create session
m_TableID.uName.pwszName = m_wszTableName;
m_TableID.eKind = DBKIND_NAME;
DBPROP rgProps[1];
DBPROPSET PropSet[1];
rgProps[0].dwOptions = DBPROPOPTIONS_REQUIRED;
rgProps[0].colid = DB_NULLID;

If I install SQL 2005 Standard on Windows 2003 Standard, is SQL limited to 4 gigs of physical RAM?
I'm planning a new system that will run SQL 2005 Standard edition on a Windows 2003 Standard platform. The spec calls for 8 GB of RAM. My experience would lead me to suspect I need to install Windows 2003 Enterprise to take advantage of all the installed memory.
We have a box with dual Intel Xeon 3.4GHz processors, and 8GB RAM, OS and Data on separate RAID5 arrays. It runs:
MS Win2k3 Enterprise for the OS,
MS SQLServer 2k Enterprise for DB,
MS SQL Analysis Services for OLAP,
MS SQL Reporting Services for reports distrib,
MS IIS for web hosting,
SPSS OLAPHub for OLAP web UI, and other small stuff...
My question is this: How should the memory be configured? Should we use the OS' /3GB switch or are there enough apps running here for the OS to need 2GB to track them? What SQLServer switches would you run? I'm not sure that I want to lock more that 3-4GB of SQL data pages into memory and starve the other pigs... How could I set this up to keep 2GB for the OS and yet really use the remaining 6GB most effectively?
All input is sincerely appreciated.

I had the drives switched out on my sever this weekend and the memory is
running at a consistent 100%.
OS: NT Server 4.0 SP6
SQL Server 7.0 SP1
Drives:
From: 60gb To: 210gb
Memory: 1gb (will be increasing to 2gb)
Pagefile: 3gb
Can anyone tell me why or what would be causing all the memory to be
used?
I have been tracking SQL's memory usage over the past few months with Perfmon. I have noticed a trend that little by little "% Committed Bytes in Use" creeps up starting at 8% and eventually climing as high at 35%. I stop and start the SQL services and the total comes back down to 8%. This happens over a week and a half or two week period. Is this normal SQL activity?
Thanks for your help!

I am going to purchase a new server to run Eastman's OpenImage software's CATALOG database. Our current server is SQL 6.5,
but it is not able to be upgraded to SQL 7.0 (known bug with this particular HP server). So I am going to buy a new one. My question is
where to find documentation that could recommend how much memory to purchase for this server. I can find scads of documents
detailing how much RAM to give SQL given a fixed amount of RAM on your server, but nowwhere can I find how much RAM to get when
buying a new server.
Any tips?

hi, i have a dell server with 4 xeon processors, 4GB RAM, running sql 7 ent ed sp2 on win2k advance server (dedicated sql server). configured my sql to dynamically configure memory. i've been monitoring the memory usage using task manager and the most sql will use is up to 2GB even on very heavy loads. why? everything i read on sql 7 ent ed tells me that it should be able to take advantage of up to 8GB of memory. also, the readings i did on win2k advance server says it supports PAE (Intel's Physical Address Extension). why isn't it using the other 2GB or at least another 1GB? if it's not able to use it, then my co's investment on the other 2GB RAM is wasted! please help!
