Hi All
Some my SQL Server are experience high memory usage.
1. How can I detect which process which process cause the big memory
usage and not released?
2. Which sql server components in this memory, and what are their usage
distribution?
Any help will be appreciated.
Thanks

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.

Process 1004:services has a virtual address space of 1,846.20 MB. This is close to the Windows two gigabyte address space limit.
When locate the process 1004, it shows 15 threads that Elapsed time for all of them is 1d, 3hrs. The Thread state is Waiting and the Thread Wait Reason is "Waiting for an Execution Delay to be resolved".
I think that 1d, 3hrs is from the time I rebooted my server.
Should I take any action? How?
Details:MS SQL 2000 dual Intel 1.2 GHz processors.1 GB RAM2.1 GB dBDynamic Memory Managment.No other apps running on this server.First question:Since I have Dynamic Memory Managment setup, Is it usuall that thesqlsrv.exe process on the server steadily climbs and is in the 800 to900 MB range. There is only about 20 MB free. In theory this is howDMM can work, but do people really see it work this way.Second question:I had users complaining about lockups in the app I have to supportthat connects to this dB. At first I thought it was the large use ofmemory, but once I was able to see in Enterprise Manager that therewas process blocking several other processes. EM then locked up and Icouldn't get to the details of what the exact process was that wasdoing the blocking. After restarting SQL services things were fine.When I checked the logs there was nothing there about a hung process.The logs seemed very sparse. Why would there not be anything in thelogs about it. The logs actually seem very thin on any information.Thanks,T.

Hi,
One of the production box running only sql server application, is showing 80% memory usage on the task manager-memory usage history right now.
We are running sql server 2000 standard version-sp3 with 2GB memory on this box. Server is not on the scheduled reboot at this point.
We have seen this behavior for this box last month that after task manager showing 90% memory usage contantly for several days, when server was manually rebooted, memory usage dropped to 35%. Now it's back to 80%.
Our DBA thinks that server should be rebooted on a regular schedule regardless of memory problem. Our network admin doesn't seem to agree with this. He is not ready to reboot the machine even with this high memory usage.
There is no noticable difference performancewise yet.
My questions are:
Is it bad that memory usage reaches from 35% constant to 80-90% or is it common? Should sql server be rebooted immediately to take care of it? Should sql server 2000 rebooted on regular basis regardless of any problems? Shouldn't sql server be releasing memory back to the OS even without rebooting? How do I find out whether server actually is going through memory problems and what is causing it?
Thanks in advance for your opinions,
Shaili
Hi All,
Currently I have an application that uses SQL 2000. The SQL server service tends to take up as much of the physical memory as possible. The problem is I also have other services relating to this application running that are very important.
What tends to happen after a period of time is SQL takes up all of the physical memory, so that the other services are using the paging file (virtual memory). This causes extremely slow response time over the network as these other services are having to parse the paging file.
Upgrading the memory is currently not an option :(
I know there is an option to set memory usage for SQL but I am unsure how this would respond in a production environment. What would happen if SQL would require more memory than what was allocated to it?
Can SQL release the memory and still act as normal?
Any input would be generously appreciated
Cheers!
I am using SQL Server 7.0 on a Windows NT machine. We have been having problems with SQL Server not releasing the memory after it has utilized it.
Currently it is configured to allow a max of 511MB memory (1024 is total on the machine). I had some advice that my best solution would be to reduce the Max Memory to a lower value (say 400 MB) to help reduce the problem.
Is this not counter-intuitive? Or is this the correct solution?
Thanks.
Hello all,How can I tell how much memory SQL Server is using on a server. OnWindows 2000, whenever I go to Task manager/processes/memory usage SQLServer seems to be showing 1,744,124K. On all of my servers withvarious size, usage of databases, all of them show SQL Server to beusing about the same amount of memory. Can someone explain this to me?Shouldn't it use more for larger databases, heavy hitting databases?Also, I normally check Dynamically configure SQL Server memory and putthe maximum threshold to a little bit less than the max on the server.The minimum query memory is set to 1024. Is that 1024 a subset of thememory used by SQL Server, or is this additional that can be used?Thanks,Raziq.*** Sent via Developersdex http://www.developersdex.com ***

I'm wondering about the memory usage of SQL Server Ce and the Compact Framework.
I've heard I can use only 32 MB per process. SQL Server Ce runs in process and my database file is about 60 MB big.
1. Does that means, I can only use for my application:
32 MB - CLR - SQL-Server Runtime - parts of my database file hold in memory
2. Is SQL Server Ce swapping parts of my database file into my process memory?
If so, is there a chance to group some tables, that they are swapped together to increase
performance?
3. Means big databases big memory usage in my process memory?
Thanks,
Stefan
Hi all,
Our Production server has 4GB RAM and is running SQL Server 7.0. By default since SQL Server 7.0 Standard Edition can take up only less than 2GB, our SQL Server is now using only 1.8GB (leaving the rest for the OS, Windows 2000 Server).
Inorder for SQL Server to take advantage of more than 2GB of RAM it is suggested that boot.ini be modified to include the switch, /3GB
Has anyone seen any issues with doing this? Is it safe to do so on the Standard Edition of SQL Server 7.0?
Thanks in advance,
Praveena
Good day to all of you
I am faced SQL SERVER 2000 Memory usage problem. I am using Windows 2000 Server SP4 and SQL SERVER 2000 SP4. When User running some in-house application software, the memory for sqlservr.exe was increased . But, when user logout from the software. The sqlservr.exe did not decrease the memory. I have around 100 Users in my company. SQL Memory will countinues increase till max memory usage in CPU.
May i know how to order SQL SERVER need to purge memory when USER was log off from the Program? Or my SQL SERVER was corrupted /missing file?
Please advice
Many thanks!

Hi All,
I'm new at SQL Server, I decided to use it in order to get all the advantages of using Vb.net and Sql. My server is a SQL standard version. I'm using a relational DB most of the time for complex select queries, everytime the server is used it performs 30 or 40 queries at the time, and I have recently realized that server consumes a lot of memory after one or two days of beign up.
Let's say that if I restart the SQL Server memory usage is about 650 Mb, but after two days memory is 1.4Mb, I have used Sql Profiler and Tunning Assistant where it recommended me to create some indexes, which indeed I created them, but that did not solved the memory problem, although some queries run faster.
My questions are:
is this memory usage is normal ?
if not, what should I check out to reduce memory usage?
Thanks in advance

We have an application that we currently run on SQL Server 2000 that works by creating a DTS package that it then executes.
Due to performance reasons, we have been considering switching to 2005, for a few reasons. Can anyone confirm clarify the following?
1) SQL Server 2000 caps RAM usage at 2GB, whereas SQL Server 2005 is only limited by the OS - RAM usage is a big current issue for us, so if upgrading to 2005 would solve this it would help a lot. Can anyone confirm my understanding of this?
2) Would using the legacy DTS in SQL Server 2005 take advantage of this RAM difference, or is it running on the old 2000 engine and only able to use the 2GB?
Thanks for any help.
Hi,
On the last Sunday 26/12/04 on 20:00 I got on one of our applications in the customer site this error:
"There is insufficient system memory to run this query."
Details:
Computer: IBM XSERIES_345, dual CPU 2.8 Intel xeo, 1,047,952 KB ram, windows 2000 server sp4.
Disk space: 4395 MB, Virtual memory: initial size 1536 MB, Max size 3072 MB. Registry size: current 14 MB, Max 90 MB.
SQL Server 2000 SP 3, two production databases (1) Data size 100 MB, log size 15 MB (2) Data size 500 MB, log size 125 MB
All the memory options are configured as default i.e. dynamically configure for memory and not changes in any sp_configure options.
SQL server is the only major application running on the machine.
Facts:
On that evening the I've checked the Task Manager and found that SQL Server use 500 MB in Mem Usage and 1200 MB in VM size.
In the query analyzer I execute the select query which results the "…insufficient system memory…" error on both databases and on the one with more data it failed with this error, but on the other database it completed successfully.
I restart SQL Server service to solve it, and as for today 28/12/04 at 08:00 it use 590 MB in Mem Usage and 590 MB in VM size.
I have checked the system with Performance monitor and didn't find any problems I use the Memory: Pages/sec, Memory: Available Bytes, Physical Disk: % Disk Time, Processor: % Processor Time, SQL Server Buffer: Buffer Cache Hit Ratio.
We have 8 user connections for one of the database and 16 for the other one.
Our system runs with this configuration for 2 months, I backup the databases FULL, DIFF and LOG backup.
It's not real time system, and the load on the SQL is medium, but we use bad queries as update for all fields in one query (please don't ask…)
I know that SQL server is greedy with the memory and released memory only if other process needs it.
Any ideas why it happens?
Thanks,
Yaniv
Hi forum readers,
we are working on a release 2.0 mobile solution right now. In our version 1.0 we did not have to worry about memory issues as our application was the only application running on our target devices (e.g. T-Mobile MDA Compact II Pocket PCs, WM2005).
Now we need to share the available memory with others. As our application relies on its SQL Server 2005 Mobile Edition database we are wondering about memory usage of that server.
We know that a Pocket PC divides its memory into Storage and Program. If our application uses a 5 MB database and 1.5 MB for DLLs and it's exe-file. These files reside in the storage space when not loaded. When the application starts up it is loaded in the program memory. What happens to the 5 MB database file? Is is loaded into Program memory as well? Are only portions of that file loaded? Or is nothing loaded at all?
Does anyone have a deeper insight into that server an can answer my questions.
Best regards,
Tobias

How to find memory usage by index in sql server?
i'm going nuts with SQL server notification thing. I have gone throigh this artical which tells how to set user http://www.codeproject.com/KB/database/SqlDependencyPermissions.aspx.

I have around 100 packages (all [packages run at same time) each package calls a stored Procedure once the Stored proc Execution is completed the package will write the log information into a log table, here how can i capture the CPU and Memory usage for execution of each stored proc.
View 2 Replies View RelatedI have been having issues with our SQL server for awhile now. It seems to run out of memory every few days and when I look at the memory dump, the MEMORYCLERK_SQLOPTIMIZER seem to take over memory and eventually cause the server to crash.
Here is the SQL verison we are using: Microsoft SQL Server 2012 (SP1) - 11.0.3460.0 (X64) Jul 22 2014 15:22:00 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.2 (Build 9200: ) (Hypervisor)..It is on a VM on Windows 2012 server. It has 20gb of RAM allocated to it and the MAX Server Memory is set to 16.5gb.
I have seen the MEMORYCLERK_SQLOPTIMIZER grow to about 11gb at the time of the server crash. Why that is happening? What is causing the memoryclerk_sqloptimizer to get so high? I have looked it up and it looks like it has to do with ad hoc requests, but is there something I can do to bring that memory down when it gets so high so that I can prevent a server crash?Do we just need to add more memory or is there a memory leak somewhere?

Hi,
My problem is the following:
tempdb is currently 20Gb data space and still some applications request more space :eek: .
Since this server contains multiple applications, I'd like to isolate the application
that uses most tempdb space / get a detailed view on who is using what.
It would be ideal if there was a way to find the SQL / temp table
that cause the problem.
Can anyone help me with this problem.
Thanks

Good day to all,
I'm new here, so I don't know if this is the right forum to post my problem. I have a web application written using C# .net 2005 (W/ajax). The application has a module that uploads data from excel file to the sql server 2005 database. w/c is by the way, i'm using SQL 2005 Express Edition, the app can upload up to more than 10,000 records from an excel file. Everything is ok until it was deployed in a test environment, while having a run through with the system, the application encounter an error after which, we cannot log in to the system anymore. I restarted the server (web and sql server in 1 machine running winxp) then I can log-in again in the system. When I'm tracing where the problem came from, I noticed that the memory usage of sqlservr.exe increases everytime the app connects to the server. I already fix some code to close some objects that might have caused the high memory usage, then I run sp_who in the management studio and there are still connections used by the app AWAITING COMMAND. Then I manually kill (using kill spid) connection that are left opened by the application. But the mem usage of sqlservr did no decrease. Is there a way to release the memory usage of sqlservr.exe? In ASP.Net ? I have a hint that this has been causing the error. Thanks a lot.
Hi,
it seems that every day SQL Server 2000 has some kind of memory leak,
the memory usage creeps above 150000 approximately 3 times per day. Is this normal? It starts at about 13000.
Is there any way that I can monitor what is causing the memory usage to be so high and maybe rectify it?
Thanks for the help.

I was on my friend's server earlier and I checked his system stats. Between sqlservr.exe and msftesql.exe he was using 2.9gb of ram. This is not a high traffic server so I felt that was just a wee bit high. What are some usage experiences you have seen? I have not worked with 2005 so I don't know what the usage should be like for a low to medium usage server. The guy that admins the db is kinda a moron anyway. He said he has said to the server admin it has been optimized, but I dont believe it one bit at 2.9gb of usage. Any comments would help.

Hello,
I need to know which of the following two methods do need less RAM.
There are 2 big tables, each about 9 M rows, and 6 small dimension tables with each about 10 to 100 Rows. The dimension tables are joined by their id's with one of the big table.
The Structure of a dimension Table looks like
CarID (tinyint), Description (varchar(20))
1 BMW
2 Porsche
I want to join the 2 Big Tables in a materialized view. Later i will run queries like
select * into #temp from dbo.vw_materialized_view where Car = 'BMW'
So, back to my question, will such a query take less memory (ram) when i joined all 8 tables before I created the mat. view or will it take less when I only join the 2 big tables in a mat.view and later join the mat.view with the 6 dimension tables?
Hope you got that ;-)
Thank you
