SQL Server 2000 Max Outs Memory Even With 32GB RAM
Oct 6, 2006
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.
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 ??
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!
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.
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.
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?
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.
Hi,I guess SQL server does not release claimed memory even if it is notused. Is there anyway to free the unused memory?Thanks,John Jayaseelan*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
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.
Hi to all, i have a very important problem...pls help me
I have a server with Windows 2003 Server (3GB RAM) and SQL SERVER 2000 running on it, my problem is that sqlserv.exe eat 2GB RAM even if on this server nothing happen....if i restart the service of SQL Server everything is ok eat just 30 MB RAM but after some minutes...after i made a simple select or a simple delete....simple things he arrive to 2GB RAM...this not happen until now(2 days ago)...the problem is that when he arrive to ~2GB RAM the statio run very slow and i receive the error "Time out expire"
this problem happens and on my local station where i have Win XP PRO (1 GB RAM) SQL Server 2000....
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: TD.

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.
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?
Hi, We have a SQL 7 / Win2K cluster and yesterday afternoon the users were complaining about poor performance. Their queries were timing out.. (Not all of them, just some on some large tables)
I ran just an ad-hoc query against the table from my machine and I also timed out. THen I went right to the box that had control of the cluster and did the same thing there and also timed out. Because of time constraints (and we are in testing mode) we tested a failover and everything was back to normal after that.
So now we want to try to figure out what could have been the problem. At the time I checked out the Memory and CPU usage and they were very low (0-5%) and using only 1/3 of the memory. It couldn't be a bad query or index because after the failover it worked fine.
Could there be something wrong with the specific box that had control at the time? I dont' know where to look?
We have several SQL 2000 databases on one server. One of the applications I'm responsible for has batch jobs that run for an hour; all activity is on the database. During this hour, other applications that use other databases on the same server experience time-outs. One of my coworkers did a count(*) on an empty table and it took 11 seconds.
We pay people to keep our servers up and running. Is this something they might solve by reconfiguring the server? It seems strange to me that a single database is allowed to hog all server resources. We are meeting with them later this week, and I'd like to have some knowledge about this; we don't want to BS'ed into buying a new server.
Hi All.I have some rather large SQL Server 2000 databases (around 60GB).I have set up jobs to re-index the tables and update statistics everysunday. This worked will for a few months. Now after a day or two ofusing it the connections to it keep timing out. If i start the jobsmanually, all is well for two days or so.Surely there can be a better solution to this ?TIA.Ryan,.
The C++ application calls the database to look up property data. Onetroublesome query is a function that returns a table, finding data whichis assembled from four or five tables through a view that has a join,and then updating the resulting @table from some other tables. Thereare several queries inside the function, which are selected accordingto which parameters are supplied (house #, street, zip, or perhaps parcelnumber, or house #, street, town, city,...etc.). If a lot of parametersare provided, and the property is not in the database, then several queriesmay be attempted -- it keeps going until it runs out of queries or findssomething. Usually it takes ~1-2 sec for a hit, but maybe a minute insome failure cases, depending on the distribution of data. (~100 milproperties in the DB) Some queires operate on the assumption the input datais slightly faulty, and take relatively a long time, e.g., if WHEREZIP=@Zip fails, we try WHERE ZIP LIKE substring(@Zip,1,3)+'%'. Whileall this is going on the application may decide the DB is never going toreturn, and time out; it also seems more likely to throw an exception thelonger it has to wait. Is there a way to cause the DB function to fail ifit takes more than a certain amount of time? I could also recast it asa procedure, and check the time consumed after every query, and abandonthe search if a certain amount of time has elapsed.Thanks in advance,Jim Geissman
I recently installed sharepoint 3.0 on our fileserver, which has our main db using MSDE. I didn't know at the time that it would also install 2k5 embedded edition, but even if I had, I don't think it would have changed my decision.
Anyway, soon after, performance on MSDE completely tanked. Queries would execute extremely slowly, or not at all. I checked the CPU and mem usage, and all were fine. No blocked sql commands either. We ended up just killing the Sql 2k5 EE service. We're moving off MSDE eventually, but I would still like to find out why it happened, and if there's a fix or workaround.
Okay, we have are running our Master Package (and therefore all related Child packages) through a .bat file. The .bat file is scripted using the following logic for an entire month of daily runs:
Code Snippet
DTExec /FILE E:ETLFinancialDataMartMaster.dtsx /DECRYPT masterpwd /SET Package.Variables[ReportingDate].Value;"2/01/2007" > E:ETLErrorLogsProcessingetl_20070201log.txt IF NOT %ERRORLEVEL%==0 GOTO ERROR%ERRORLEVEL% mkdir E:ETLErrorLogsArchive20070201 move E:ETLErrorLogsProcessing*.txt E:ETLErrorLogsArchive20070201
DTExec /FILE E:ETLFinancialDataMartMaster.dtsx /DECRYPT masterpwd /SU /SET Package.Variables[ReportingDate].Value;"2/02/2007" > E:ETLErrorLogsProcessingetl_20070202log.txt IF NOT %ERRORLEVEL%==0 GOTO ERROR%ERRORLEVEL% mkdir E:ETLErrorLogsArchive20070202 move E:ETLErrorLogsProcessing*.txt E:ETLErrorLogsArchive20070202
etc...
Generally it takes about 40-45 minutes to run one days worth of data. However, we have found unpredictable instances where the job will take 3 hours or even 6 hours and appear to hang....
The weirdness sets in when we kill the job and rerun it. In all instances of a rerun, the job will execute in the normal 40-45 minute time frame. Obviously, we would like to institute some sort of logging, monitoring and error handling....including if need be a method to timeout a process and restart it.
I am reviewing the WMI (Windows Management Instrumentation) Task but I'm not entirely convinced that it's the right tool for the job.
Questions:
Has anyone else experienced the type of processing behavior that I described? Has anyone been successful at using WMI or another process to monitor and timeout packages? If so, are there sample packages or a good tutorial that maps it out? Unrelated to this issue, we also have instances incomplete processing logs. The logs don't finish writing and the weird part is that they all end at the same point, does anyone have experience with incomplete job logs?:
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 everyone! I'm new to this forum and I suspect I'll be using this forum frequently. Good stuff.
Allow this question may appear to be Web-related, I think the problem is with what I'm doing with the database. Please read.
I'm trying to implement a page tracking solution using ASP and SQL 2000. It basically writes a new record to a table every time a user visits a page on the site. It appeared to work fine at first, then I've increasingly been getting time out errors on my pages -- all pointing to the include file that fires the database write.
Here's the code that's referenced on every page:
Set Conn = Server.CreateObject("ADODB.Connection") Conn.Open "dsn=x;uid=y;pwd=z;"
Set objRecordset1= Server.CreateObject("ADODB.Recordset") objRecordset1.Open "SELECT * FROM table",Conn,1,2 objRecordset1.AddNew objRecordset1.Fi elds("PAGE") = Left(request.servervariables("SCRIPT_NAME"),100) objReco rdset1.Fields("QUERY_STRING") = Left(request.servervariables("QUERY_STRING"),100) objRec ordset1.Fields("DATE") = Date() objRecordset1.Fields("TIME") = Time() objRecordset1.Fields("PLATFORM") = Left(request.servervariables("HTTP_USER_AGENT"),100) obj Recordset1.Fields("REFERRER") = Left(request.servervariables("HTTP_REFERER"),100) objRec ordset1.Fields("USER_IP") = Left(request.servervariables("REMOTE_ADDR"),20) If Request.Cookies("TEST")("ID")<>"" Then objRecordset1.Fields("VISITOR_ID") = Request.Cookies("TEST")("ID") End If objRecordset1.Update
Conn.Close Set Conn=Nothing %>
After taking out the reference to the above code everything speeds back up. So, I know the performance hit and time out issues have to do with the code above.
Is it the simultaneous write to the table, the constant opening and closing of the recordset, the cursor type, the lock type – or combination of things?
We have 4 clustered SQL2000 Servers each contains information specific to its application related to customer information in a casino player tracking database. My problem is as follows On the Playertracking database I can join and return information from the tables there with no problems the performance accross the decently sizable transactional based table is pretty decent. The problem is I need to filter this query down by the Type of machine the customer plays. The child key exists in the playertransaction table the parent key is on another server. Here is the lay out of the tables unecessary information from the tables were truncated for brevity.
CREATE TABLE [dbo].[PlayerSession] ( [PlayerId] [int] NOT NULL , [Mnum] [int] NOT NULL , [CoinIn] [money] NOT NULL , [CoinOut] [money] NOT NULL , [Games] [int] NOT NULL , [Jackpot] [money] NULL , [Win] [money] NULL , [TheoWin] [money] NOT NULL , [PlayerMod] [tinyint] NOT NULL ) ON [PRIMARY]
-- Player Demographics information CREATE TABLE [dbo].[Player] ( [PlayerId] [int] NOT NULL , [Status] [char] (1) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [Title] [varchar] (5) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [FirstName] [varchar] (40) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , [MiddleName] [varchar] (40) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [LastName] [varchar] (40) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [SSN] [varchar] (16) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , ) ON [PRIMARY]
--Machine Information that links to Machine Type table
CREATE TABLE [dbo].[Machine] ( [MNum] [int] NOT NULL , [MachineTypeId] [smallint] NOT NULL , ) ON [PRIMARY]
-- Machine type code table
CREATE TABLE [dbo].[MachineType] ( [MachineTypeId] [smallint] NOT NULL , [Denom] [int] NOT NULL , [Par] [decimal](6, 2) NOT NULL , [GameType] [varchar] (40) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL , ) ON [PRIMARY]
From the server where all the player information is ran I can query the linked database for the machine and machine type information like this.
SELECT m.MNum, mt.MachineTypeId, mt.GameType, mt.DisplayType FROM ACCTV.Accounting.dbo.Machine m INNER JOIN ACCTV.Accounting.dbo.MachineType mt ON m.MachineTypeId = mt.MachineTypeId
This is the information I am trying to get out but the query times out on me.
SELECT Player.PlayerId, Player.FirstName, Player.LastName, SUM(PlayerSession.CoinIn) AS sumCI, SUM(PlayerSession.CoinOut) AS SumCO,SUM(PlayerSession.TheoWin) AS SumTheo, AVG(PlayerSession.TheoWin) AS AvgTheo, SUM(PlayerSession.Win) AS SumWin, AVG(PlayerSession.Win) AS AvgWin, mt.GameType FROM Player INNER JOIN PlayerSession ON Player.PlayerId = PlayerSession.PlayerId INNER JOIN ACCT.Accounting.dbo.Machine M ON PlayerSession.Mnum = M.MNum INNER JOIN ACCT.Accounting.dbo.MachineType mt ON M.MachineTypeId = mt.MachineTypeId GROUP BY Player.PlayerId, Player.FirstName, Player.LastName, mt.GameType
The other option would be some sort of SubQuery but I dont know how to return results from the subqueries to the root query to be returned to the restulting recordset. I am not necessarily looking for an answer more of looking for a direction to go to find my solution.
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?
I recently changed the max. memory option in SQL from 24 GB to 30GB but the perfmon counters still only show 24 GB. Any ideas on why it is not recognizing the change? The server has Win 2003 EE and 32 GB of RAM.
