SQL Server 2000 -- Taking Over My Memory
Feb 3, 2006
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,

We have run into an issue on a dedicated SSAS 2012 SP1 server where the allocated memory is not being utilized, causing some slowness in use, connections, and queries.
Total Memory on the server is 512, and after startup, the utilized memory gets up to a max of 60GB and stops there. Checking the Resource Monitor, msmdsrv.exe is only taking around 39GB overall. With the current properties, that should be at 330GB. Am I missing something in the settings or in configuration that should be changed?
Version: SQL Server 2012 SP1 Enterprise (11.0.3000)
OS: Windows Server 2012 Datacenter - Fully patched and up to date
Databases: 2 Tabular models
Server: 512GB RAM
Current memory configuration:
Hard Memory Limit - 0 (Default)

I have a custom .net application that uses SQL 2000 server. All users are compaining performance issues and white-outs while they are using the application. I am almost certain that it's the SQL server that is the curprit. All the other components involved in the application hardly has any CPU or memory usage when I check the performance in the task manager.
On SQL server, I see that the process sqlserver.exe is taking like 2.8GB of memory. Is there a way to find out which exact SQL query or process is taking so much of memory? I belive there may be a bad SQL process that is stuck and taking all the memory? Is there a way to find out?
Thanks

I have created a SSIS package that reads 500 text files splits them into 4 raw files then reads them again and writes then to 4 database tables different Tables.
The reason form this is that my raw files have multiple types of records in them and it is only 1 Coolum. I split this out into the different types of records and load whole rows into the database.
ie input 1 txt file
<T6>
1:1000178
3:18148821-00
5:40204043
6:1
17:EX201036259NZ

T5 Table gets a new record

and T1 Table get a record
18148821-00
Anyway all this works find but I find that the DTExec process work fine until it has used up all the memory in the laptop in general it take 400megs to run this SSIS. I'm wondering am I missing something like don't run in a transaction. I know in the old DTS you could commit on each package and how do I turn all logging off eg what you see in the DOS box (can I do this?) would love some help on this and if anyone want a copy of this ssis package ie your trying to do the same then I'm more than happy to email it.

Hi,
Situation: I have a web application that is running on a server. IT has told me that the application I developed is taking up enormous amount of ram. It seems that the amount of ram that is taken up, is slowly increasing. About 10 megs per hour (memory leak). Furthermore, he has informed me that the ram is taken up by the sql. My senior developer told me that I probably have sqlconnections open that are not closed. I have checked through the application and it seems they are all closed properly. But I may have missed some, as the application is pretty big.
Questions:
1. Is there an application or piece of code that can monitor how many sql connections I have open during runtime?
2. Could there be any other common causes to such a kind of memory leak.
Any help with this matter would be very much appreciated.
Thank you for your time.
Sincerely,
Jeff

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

Hi,
We have 32 individual publications setup on SQL 2000 and have 32 distribution agent running against it. I think each distribution agent opens a process called distrib.exe in Windows task Mgr.
Problem I'm having is that these 32 distribution agents are taking up fair amount of memory 1/2 gig and each process seem to be ever increasing in memory usage so I suspect a memory leak?
Is there something I can do to fix this problem? I don't want to upgrade memory as we already have over 1 1/2 gigs on this machine and it would not be feasible if we have a memory leak.
thanks!

Hi Folks:
We´ve migrated from SQL Server 7.0 EE to SQL Server 2000 in a 8processors, 8 GB RAM server, using W2000.
All seems go ok, but after reorganizing indexes, when we want to recover free space in the differents files using DBCC SHRINKFILE, that recovers are taking the triple of time than with previous SQL Server 7.0.
Shrinking big files (6GB to recover 1.5 GB), previously taking 3 hours now are needing 9 hours.
Any suggestion or help will be appreciated.
Best Regards.

I would like to know recommendations on automate the following:
1. I want to know how to take data from various sql server 2000 data queries and load the data onto excel spreadsheets in an automated method. Some of the data loaded into the excel spreadsheets load detail data and some load data into pivot tables.
Is there any way that the data can be taken from sql server to the excel spreadsheets using odbc connections?
2. Some of the data taken from sql server 2000 database is loaded into pdf files. Is there any way this process can be automated?
Thanks!

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!

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.

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.

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

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

Hi,
I have a table with 48 million rows,when i executed following update query it is taking 10 HOURS in SQL SERVER 2000 with SP1.
Where as when i executed same query in SQL SERVER7.0 with same table then it is taking 13 MINUTES. Comming to Machine...SQL 2000 Server has more processors and greater memory than SQL 7.0 m/c.
It looks strange but this is true.Does any one faced such problem..is there any bug in SQL 2000?????
Here is Query::
update cus_pay_jan_dist set univ_regdate = b.dayid
from cus_pay_jan_dist a with (nolock), tm_dayids b with (nolock)
where a.univ_regdate = b.dayidnum and a.univ_regdate like '2001%'

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.

I would like to ask regarding the memory allocation fo SQL Server 2000. For example if my Data Server have 8GB physical memory installed how much memory can SQL Server 2000 utilize? Based on my research and understing SQL 2000 Server can only utilize 3GB memory? But using the AWE you can set the memory to a maximum server memory?
