SQL Server 2000 And Memory Consumption
Sep 14, 2005
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.

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

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.

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 have SQL Server 2000 STD installed on a Windows Server 2003 STD machine. It's essentially the only app on this box. I have 4GB of RAM installed. SQL is configured to dynamically allocate memory. I run a batch file daily to restart the SQL services as SQL does not seem to release memory once it's got it. I don't think this is a problem because, like I said, it's basically the only app. But I want to make sure my OS memory settings and SQL's memory settings are optimized. Will adding the /3gb switch to the boot.ini file make a difference? Also, can someone educate me a little on PAE and AWE?
Thanks

Every day or two I have to restart my SQL Server because users are receiving timeouts and very slow page loads. My mem usage in Task Manager show that SQL Server is at 1,200,000k compared to 400,000k when I restart it. Performance Monitor also shows that Buffer Manager/Target Pages and Total pages are maxed out. Any advice? Thanks!

Dear All,
We have a Windows 2003 Enterprise server with SQL Server 2000 Enterprise on it. This has the AWE settings for 'max memory setting' to 5120MB. This server has 6GB of memory, or rather about 5.8GB due to PAE. From yesterday morning the server has become almost unresponsive when the SQL service is running, and pretty much all the memory, ie < 1MB on average is listed as being free.
The database has been growing constantly and is now 46GB, with database file size of 67GB.
We moved the database onto a new box which was being prepared for another service, and this has 8GB or ram and no AWE settings. It is running fantastic.
We are going to rebuild the original box and the SAN structure, but I want to do some fiddling before we do. I was going to set awe-enabled to 0 to see if that setting was allowing the OS to have no memory, but from reading http://www.microsoft.com/technet/prodtechnol/sql/2000/maintain/failclus.mspx it says If AWE is enabled and is taking too much memory, SQL Server must be shut down to reconfigure it, causing downtime (which makes a high availability option such as failover clustering less available). Because the memory pages used by the instance of SQL Server are taken from the nonpageable pool of Windows memory, none of the memory can be exchanged. This means that if the physical memory is filled up, SQL Server cannot use the page file set up on a physical disk to account for the surplus in memory usage. How do you reconfigure AWE settings if the SQL service is shutdown?
Also, how can I figure out whether the server is deficient in physical RAM, or it is just a 'max memory' setting we need to tweak, or is it just trial and error?
Incase it might help, we have ~3 meaningful DB's on the server apart from 'master'. One is an archive DB ~80GB, one is ~5MB and the live DB which is the size mentioned above. Unfortunately I don't know table sizes.

One of our servers has 20GB of memory and SQL server has been allocated 18.5 GB out of it, however SQL Server only uses about 9GB or so.
OS: Windows 2003 Server
MS SQL Server 2000 SP4
awe enabled
min & max server memory (run values) are: 18432
/PAE switch in boot.ini
any help why SQL server is not using 18.5 GB allocated to it, would be greatly appreciated?

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!

SQL Server 2000 SP3 on a Dell dual 2.4GHz Xeon box 3GB RAM Windows 2KSP4. Two aplication dbs, each less than 2GB in size.Had a problem where we would run Solomon queries and what not againstthe box. It had 2GB RAM, and sqlserv.exe would take up to 1.85GB ofRAM, exhausting the physical RAM on the box. SQL would choke and theSolomon users would have problems, and I would have to restart the SQLservice.I added another GB of RAM, bringing the box to 3GB, and increased thepaging file. The OS sees it, and SQL sees it. I check EnterpriseManager, and tell SQL to dynamically configure memory, and it offers anupper limit of 3071MB, so it "sees" the 3GB.I can stress the box with queries to the point that sqlserv.exe takes1.99GB of memory (as viewed through Task Manager) and then SQL serverchokes. It never goes past 2GB, and the OS and box continue runningfine.Does SQL server 2000 have some upper limit, or do I just need to changesome setting through EM?Thanks.

We use MSDN SQL 2000 , the enterprise edition for our development servers,
which have always had 2GB RAM.
Now they are bringing in a Win 2003 Enterprise with > 12GB RAM .
They want SQL SERVER 2000 to use AWE memory up to 12GB . Is there any limitation
on MSDN Ent. Edition using more memory.?

I am running SQL Server 2000 on a desktop PC. Just recently upgraded my PC to 2gig of ram from 1 gig, in part, to try and fix the problem below. Didn't work. Have SP3 installed but not SP4 at this point.
When I open up query analyzer and edit some code, regardless of whether I actually execute the code, SQL server eventually sucks up available and cached memory to the point that my system comes to an effective halt --takes forever to do anything either in SQL server or other applications. In the task manager PF Usage climbs to just over the 2gig memory limit.
I conceptually understand the dynamic memory operation of SQL server ... but why is it sucking up most available memory when nothing is executing?
Is there a way I can release/clear the memory? Ideally, code that coould be run under a stored procedure would best meet my needs. Right now, I am "fixing" by shutting down and then restarting SQL server.
Thanks,

Good day everyone!
The issue I'm going to pose here has to do with SQL Server allocated memory BEING EXHAUSTED by an application (a simple data receiver from GPS units) when the number of units connecting to it is considerably increasing.
This happens to an extent that no more connections from the units are valid and therefore lots of data (Afterwards) is being lost.
This causes a real problem with the installations and the projects which are running the system.
I will hereby post all of the info which might be useful for any Database Experts among you, so you can perhaps help me figure out the source(s) of the mentioned problem, and possible solution(s) of the issue.
1- The Operating System used:
Windows 2003 Server (Ent. Edition)
2- The Database Server used:
Microsoft SQL 2000 Server
3- The amount of memory:
1 GB (but on some sites there are 4 GB and the same problem
is faced)
4- The conditions where the issue happens
When the amount of the received data - which gets written to
the SQL Server tables - exceeds a certain limit.
5- Number of applications used:
We are using two applications:
a- The receiver, which is a simple application that only
receives the data from the GPS units installed at the cars
of the clients' fleet(s), and writes them to the database
(Day and Night - running all the time), so the memory used
gets bigger and bigger till it floats the memory used by
MS SQL Server 2000. As a result of this the connections
made from the units furtherly to this point (to the receiver)
are not being received and written to the database.
b- the other application is quite heavy.. it does data
management on SQL Server 2000 and exhausts the CPU.
It reads from tables and makes analysis for GPS data...
This is done while "vehicle tracking".. so it makes
calculations on the received data and stores them into
output tables.
6- The programming language used in writing these 2 applications:
Delphi 7
7- What are we doing right now to handle this problem?
We need to flush the memory on periodical basis.
This is being done by stopping the SQL Server, or by
restarting the PC.
And it is not solving the problem entirely, especially that
there must be a way to handle this.
BTW, the memory is not being flushed when we turn the
application off.
8- What do we need to know?
a- We've found, after research, that there are "Temporary tables" or
objects in SQL Server 2000, that the DB system creates.. also page
files, and temp tables.
What are these for? And does handling them in a certain manner help
solve the problem?
b- Is there a way to monitor our applications to see where they are
increasing the usage of memory and how this is happening?
c- Is there a script that writes to the database that we can use to see if
the problem is from our applications? And in case it is, then is there a
command we should write or a function or script we should run in order
to flush the MS SQL 2000 Server periodically, so that it doesn't flood?
What comments can you have on this issue?
Are there solutions at hand?
I thank everyone for trying to help!
All the best :beer: :beer:

Hi
I am joining the thread that initially Mike started. We have a x64 bit SQL Server with 32GB RAM. On start up sqlserver.exe starts with 15 to 20MB of RAM. After that the memory gradually increases at a step of 100MB and reaches 31.8 GB at the end. We don't see a out of memory situation so far and the memory remains the same, once the sqlserver.exe reaches that level we are facing application in stability issue. There is no other application running in this server. At present the database size is 28GB and we have employed the following,
There is a database replication running
A weekly maintenance plan to reindex, backup and other maintenance is running.
There is a log back up job which runs once in 2hrs time.
The temdb size grows to 3gb max. We didn't see any temp table created left out orphan in the temdb.
We have the required indexes placed in the tables to reduce the scan time. Also the server is configured to use dynamic memory allocation that is all are factory settings.
The database is encounters on an average 200 to 500 connections at a time. One observation is the memory goes up as soon as the replication starts, this is at one of the 2 servers.
Please advise what is causing this issue and how to go abt it.

Hi all,
We have an SQL 2000 Standard SP4 system with 3gb of RAM running on Windows 2003 Server R2 Standard.
The SQL memory usage of this server flatlines at around 1665mb and will not go any higher.
I understand SQL 2000 Standard on Windows 2003 Server Standard has a 2gb memory limit, however why wont the memory push up to this limit? The OS shows there is around 700mb of the 3076 unused (SQL uses 1660, windows uses around 700 making the maximum used around 2300 of the 3076)
I have set the /3gb switch on windows boot, I have changed the SQL memory configurations many different times. If I try and set 'min server memory' to anything over around 1500mb I get the error on SQL startup;
Warning: unable to allocate 'min server memory' of 1720mb
In the above example surely if the Server has a 2gb limit it should let me set say 1720/2048 ? or 1920/2048 or even 2048/2048, however anything over around 1500 generates the above error.
Our server continues to flatline at 1660mb, any help to squeeze out an extra 200-400mb of RAM would be appreciated or an explination as to why it can not be done.
Thanks for your help

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?

Could anyone inform me how much the conventional memory SQL7 Enterprise on Advanced Server 2000 can have?
The SQL is on an active/active cluster. Currently each runs at 2GB of memory, with available memory for failover. I am planning to add another 2GB to each SQL node. Is this possible? Are there any configurations I need to do? Do I need to set AWE enabled? and How much?
Your help is greatly appreciate.

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?

Does anyone know how or where to adjust Ram Memory usage for SQL 2000.
I've just added Changed the 512 MB Ram that came with the Server and Exchanged it with 4 GIG Ram . Is it a good Idea to allow only 2GiG for SQL . I 've heard that SQL will take/use all Ram that you install if you let. If this is true
Can anyone advise on how/where to make adjustments. Thank You...

I am looking for recommandations regarding the memory distribution for SQL 2000 server. In the memory tab of the server properties you can define use a fixed memory size or dynamically configure SQL server or even reserve physical memory for SQL server.
Are there any hints available or must it be handled according trial and error?

Running sqlserver 2000 on a w2k server with 1gb of memory. After a reboot the memory usage is around 500m but quickly climbs. At 1 point it was up to 1.5gb so it must have been swapping. Are there any good docs about this or any recommendations on how to limit sqlserver from using all the memory. It is the only application on the server so it isn't affecting anything else so maybe it isn't a problem. I just wanted to get people's inpit on this.

We have a SQL server that has a failover cluster on our network. We are looking to updrade the memory by adding a couple gigs of ram.
We don't need to upgrade the failover cluster to have the exact amount of memory as the primary do we?
