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?
View 8 RepliesHi,From a previous sys-admin I inherited a a MS-SQL (2000) machine with 3instances. It is a nice machine with 4 Gb of memory but the memory allocationis very weird:Instance A: 1400MbInstance B: 1000MbInstance C: 80Mb (!)Instance C is performing badly under a bit of pressure which seems not strangeconsidering these allocations.With that in mind, is there a way to check and re-allocate memory? I'd like tosee if the instances really need these amounts of memory and if not, to movesome over to other instances.Thanks!Dries Bessels

hai,
once again pavan. i need some clarification on this issues
how sql server allocates memeory for the instances.
means
procedure cache
buffer cache
log cache
system data structure.
could you please provide information regarding this issue
regards,

I have windows 2003 with ms sql 2000. The machine has 3.6 gigs of ram and only runs ms sql, nothing else.
Whenever the first query is made sql will allocate as much as 1.5 gigs of ram which is just killing the system. This system reboots nightly so this first query happens every morning.
We have tried setting the min and max memory of sql, as well as the reserver memory setting to see if it will preallocate all that memory but we've had no luck.
Is there a way to make SQL allocate all that memory ahead of time? maybe make it cache some tables or something?
I know very little about MS SQL so please be very descriptive about possible solutions or troubleshooting steps.
Thanks,

How to find how much memory allocated to SQLCLR by sqlserver. Also is there any way to determine how much memory my code needs to run? Thanks in advance.

EXECUTE master.dbo.xp_sqlmaint N' -D TempDB -CkDB -CkCat '
I run this job on say all DB's and recieve a memory allocation failure.
I run checkdb in QA and it works fine any ideas?
Thanks.
I'm log shipping to AWS. Currently, we are shipping from a server with 64 GB RAM to one at AWS with 30. It's not a massive server but does have periods of high usage when certain jobs/tasks run. It's been running fine for a year but the server size is large and is barely used. My understanding is that for simply log shipping, we don't need a lot of memory and I was hoping to drop the instance size down and use an instance with 16 GB Ram instead. It would save thousands per year.
View 2 Replies View RelatedI’m setting up a server for development that will have one instance of SQL Server 2000 Standard Edition and one of SQL Server 2005 Standard Edition installed.
The server has a total of 3.5 GB of physical memory, so I was wondering about the best way to allocate the memory. Should I just let both instances have the default allocation and let them fight it out for memory as needed, or allocate a memory limit for each instance?

I am setting up a server under Windows Server 2003 Enterprise Edition (SP1) and SQL Server 2000 Enterprise Edition (SP4). The new server is a AMD opteron with 32 GB of memory. I noticed that PAE is enabled automatically by Windows 2003. Should I enable AWE for SQL Server 2000 and specify Max and Min amount of memory for SQL Server ?? Is there a limit on how much I could specify in MAX memory for SQL??
This is the first time I have a server with so much memory so I want to make sure that I do the right thing. In the past I only have servers with 8 GB of memory and we just enable AWE and specify Max memory to 6 GB or so.
Any advise is very much appreciated. Thanks,
I have gotten mixed comments on this topic. I have a 64 bit machine running 64 windows 2003 standard and 64 SQL 2005 standard with 8 GB of RAM. We want to upgrade it to 32 GB. What is the best approach to do this? Dynamic or Stattic giving min and max server memory a value ? and if static what value should I use for 32 GB knowing that this box is only being used for SQL.

Are there any *negative* consequences to SQL Server 2000 Standardpaging to disk more often if one reduces the amount of available RAMfrom 2.0 GB to 1.5 GB to give the OS and other apps enough RAM, otherthan things possibly being "slower" and whatever wear and tear couldhappen to the disk drives??Or is it better to add in more RAM per se to bring the server up to 4GB (Win2k3 Svr SP1)?? (it has a 4GB pagefile)Is any information available about judging how much RAM the OS (Windows2003 Server) should have available?? Does IIS require a lot of RAM??Thank you, Tom
View 1 Replies View Relatedsql 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 ??

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?
Thanks for any info

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 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.
View 5 Replies View RelatedI 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.

Greetings all!
On one of our intranet SQL servers running under Windows 2000 SP 3,
MSsql 2000 SP4 seems to gradually "eat" away all available memory (with no obvious reason for it) until a certain limit is reached, forcing the server to slow down substantially since the OS has to SWAP continuously.
I would appreciate any suggestions at this point on how to tackle this problem :)
Thank you!

Hi,
I have one application in two different companies with MSSQL2000 running on Windows2000 Server and Windows2003 Server.
It seems that memory needed for MSSQL2000 as displayed in task manager is increased every day.
Does anybody knows anything regarding memory leaks in MSSQL2000?
How can I find what version of service pack have I installed in a MSSQL2000 server machine?

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?
I have an Active/Active/Passive cluster with 64GB RAM on each node running SQL 2000 EE, AWE is enabled as well as the PAE switch, all is dandy with that.
Question:
Should I configure each SQL Instance to have only a max mem usage of 32GB in the event both failover to the same node ? or will the memory allocation be handled without any issue if each node is configured to use 64GB ?
Thanks.
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 have a new server (4 dual-core CPUs and 8GB ram) with Windows 2003 x64 installed. We need to put SQL 2000 on the system and want to maximize it for sql performance (will be dedicate to SQL). Do we enable awe in SQL? Are there any 3GB switches we need to put in the boot.ini for the 32-bit subsystem? Should we use the 32bit version of Windows and just use awe and pae?
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,
