Server Mem Usage
Sep 25, 2006
Hello.
I am using a SQL Server 2005 devenv and each time I open my ssis
package, the server mem usage jumps up to almost 400mb ram. On opening,
tries to validate each data flow task and that takes forever, I have
delayed validation however still takes time to load. I am currently
using terminal services to access visual studio and the project has two
ssis packages that myself and another developer are working on, could
this have something to do with this?
In saying this, everything worked perfectly a week ago, now its
extremely frustrating.
Anyone with feedback would be greatly appreciated.
Cheers

Hello, When I am seeing SQL Server 2005 Management studio Server Dashboard> I am seeing my(USERS) databases and msdb database usage is very small % of in CPU Usage(%), Logical IO Performed (%) Usage pie chart.
90% of Total cpu usage is showing for Adhoc Queries. what excatly this means in Dashboard? if application uses more than it would have shown in Database level or not?
sicerely this dashboard is good, if any one is watching daily, please advice their experiences here.
Thanks in advance. Hail SQL Server!

I have recently installed SQL Server 2005 (Developer Ed) + SP1 onto a VMWare based Windows 2003 + SP1 server.
SQL Server works fine when connecting to it using Mangement Studio on Windows XP.
However, I have noticed strange CPU usage on the server which seems to be caused by Management Studio (either directly or indirectly).
When no-one is connecting to the server using Management Studio, the server happily ticks along with CPU usage around 1-5% range. However, as soon as someone connects to the SQL Server instance using Management Studio the CPU usage begin to go up and down constantly.
The CPU usage ranges from 5-50% and it goes up and down (fairly regularly) every few seconds. It does this even when nothing is actually being done in Management Studio. The moment Management Studio is closed, the CPU usage goes back to normal.
The processes on the server that appear to be causing the CPU spikes are services.exe and wmiprvse.exe.
On a possibly connected note (though possibly not), the Security log in the server's Event Viewer shows that there are logins occuring every minute or so (most of the logins are from my account).
Any ideas?

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

Has anybody encountered SQL SERVER 6.5 using 100% server CPU at startup with no other processes running on the NT server or accessing SQL Server?
I have tried starting up in minimal config mode to access the config values, but am having SQL Server hanging by that point as CPU usage has hit 100%
If anybody knows an answer please let me know.
Thanks

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!

Hi,
For the last week, our production SQL server is running very slow and causing the CPU usage to go 80-100 % almost all the time. This causes certain queries to time out. Our application has never timed out before ever. Also, we did not do any updates on our production machine or installed anything recently.
Has anyone of you ever experienced this issue? If yes, then what did you do to resolve it? any help would be greatly appreciated.
Thanks for your help!

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 ***

Hi,
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

Like most enterprise there is the database administrator (dba) and there are the developers(dev). The dba are conservative while the developers are also exploring their options.
One of the current usage I'm experimenting on is to provide data visualization - image for the data. Like most I needed to "create" the System.Drawing assembly in the database, marking it unsafe.
During my testing, my code had some exception and that brought down SQL Server.
I read that the CLR is better compare to the sp_OAs as well as the extended stored procedures written in C++ because it isolates the execution in a separate app domain and termination is clean - in case of any errors, it should not bring down SQL Server.
Also I read marking assembly unsafe void these benefits of isolation.
Instead of having to manage the situation where it involves code review by the dba and asking the dba to take some risk, is there a technique where all CLR code that runs in the production server does not pose stability issues.

Hi All,
I had two Window NT 4.0 Server, say A and B... We recently upgraded from MS SQL Server 6.5 to MS SQL Server 2000 on Computer A, and for Computer B, I installed SQL Server 2000 from scratch. These two have a same RAM(512MB) and CPU speed...so the setup for hardware is almost identical...
For server A, there are around 10 connection to this SQL Server...
For server B, there are also around 10 connection to this SQL Server...
The database for SQL Server B is a copy from SQL Server A.... I restored the database on SQL Server B from the backup dump of Server A...
We have a store procedure called usp_GetMemo(ID Interger) ... we feed ID number to this store procedure and return its return Description... this table has ID column and it's Non-Cluster index, allow the duplicate row... there are 1.7 million records for this table...
Here is problem... whenever i execute more than 100 times for this store procedure(usp_GetMemo(ID)) continuously, the CPU usage of Computer A is 3 times bigger than computer B....
I did run the command "DBCC DBReindex" , "Update Statistics" for this table on computer A, but did not make any difference...
Keep in mind that Computer A has been upgraded to SQL server 2000 while Computer B installed from scratch... would that make difference somehow?? Before the upgrading, the CPU usage of computer A is the same as Computer B...
Any help will be really appreciated,
Thanks alot,
Kim,

Can anyone point me in the right direction to find documentation for the problem below?I need to store and retrieve ten fields of 16-bits each for testing 16 true-false conditions (a total of 160 bits in each record) so I think I'd like to use ten 2-byte binary fields (160 "bit" fields would be quite unmanageble, if even possible [I think there is some kind of limit to the number of fields in a single record]). I'm not quickly finding in the SQL Server's online documentation how to test for, use and update binary fields. I'll keep looking, but can anyone point me in the right direction? I'm using VB, if that makes any difference.

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

Hi all,
We have our SQL Server 2005 installed in a server with below specifications.
MS Windows Server 2003 R2
Standard x64 Edition
Service Pack 2
Intel(R)Xeon(R)CPU
5160 @ 3.00GHz
3.00 GHz, 8.00 GB of RAM
The issue is ,
When a query window is opened and a procedure is executed or a DBCC command is executed , the PF usage keeps on increasing and reaches the maximum 8.81 GB and remains there forever even if the query is stopped and the session is closed.
The CPU usage also shoots up and stays between 90 - 100 %.
Now, it is not possible to open a new query or do any operation in the SQL server and a Timeout Expired error is thrown.
My questions are ,
1. Is that good for the SQL server to occupy the total RAM ?
2. Is the performance related to the RAM space occupied by SQL server ?
3. What should we do in order free the PF usage after the a process is complete ?
4. Have anyone faced similar scenario ? Any solutions ?
Thanks for your time & any help should be apprecitated.

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,
I logged some of the parameters of my SQL server using the Performance monitor into a log file - smn5.log & the log settings in smn5.pml. I started the log and the log file (smn5.log) started growing in size indicating that it was collecting data.
I then went to Options button and said Save. After this in the File menu, I selected Export Log and saved it in a .CSV file, expecting it to contain the Logged data. However, it contains only the Log settings as shown below :
--------------------------------
Reported on L&T1362
Log File C:MSSQLLOGsmn5
Interval: 15.000 seconds
Object,Computer
SQLServer-Log,ERMINTRUDE
SQLServer-Procedure Cache,ERMINTRUDE
SQLServer-Locks,ERMINTRUDE
SQLServer,ERMINTRUDE
SQLServer-Log,FLORENCE
SQLServer-Procedure Cache,FLORENCE
SQLServer-Locks,FLORENCE
SQLServer,FLORENCE
---------------------------------
Could some one please tell me how to gather and view the logged information ? smn5.log contains 10MB of data - the perf. monitor shows that.
Thanks

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
