Stress-Testing SQL Server
Jan 28, 2005What do you recommend for stress-testing the performance of key stored procedures (they have been identified) for our application? The parameters can be programatically selected, for example:
Select 'exec my_proc @id = ' + Cast(id As varchar)
From myTable
Where foo = 'bar'
I have the Support Tools Available For Stress Testing & Performance Analysis (http://www.microsoft.com/downloads/details.aspx?FamilyId=5691AB53-893A-4AAF-B4A6-9A8BB9669A8B&displaylang=en) from Microsoft's site and they are pretty good.
Recommendations appreciated, and thanks in advance!
Physical RAM Stress Test
Nov 20, 2006Hi,
I have a new server where 32GB of RAM is installed and I have user databases on this server.I am using SQL server 2000 Enterprise edition and Platform is Windows 2003 adv server, which supports upto 128GB of memory.
sp_configure 'awe enabled' is set to 1 and at OS level, AWE is enabled as well.
max server memory (MB) is 2147483647
I was doing some stress test on this server but memory usage doesn't go beyond 180MB....can someone suggest a test for physical RAM ?
How can I make sure that application will make full use of available physical memory?

BULK IMPORT Stress
Jul 26, 2006I am trying to import a data file, which is tab delimited, using BULKINSERT. I have used BCP to create a format file, since the destinationtable has around 20 columns, but the data file has only three.Here's the problem: The columns I am trying to import comprise ID (anint identity column), Name (a varchar(255) column and Status (a smallint column). The data file contains identity values for the firstcolumn, so I am using the KEEPIDENTITY modifier. The Status column ismandatory, so I have set all rows in the data file to zero for thatcolumn. All of the other columns in the destination table either allowNULL or have default values. When I BULK INSERT the file using theformat file the identity columns are NOT imported and the Status columngets value 3376. The Name column is the only one that gets importedcorrectly. Here's the format file:8.031 SQLINT 0 4 " " 1 ID""2 SQLCHAR 0 0 " " 2 NameSQL_Latin1_General_CP1_CI_AS3 SQLSMALLINT 0 2 "" 4 Status""Sorry it's a bit messy.Where is 3376 coming from, and why are my identity values for column IDnot being imported?

Stress Testing A Datawarehouse Hardware Set Up
Mar 8, 2002I am testing different raid setups in a Datawarehousing environment.
E.G
3 X Raid 5 (with four filegroups)
3 X Raid 10 (with four filegroups)
At the moment I have chance to trial different hardware configurations.
I want to measure what are the performance differences
I need to stress test these configs. Is there any tools I can use to do this.
Any loads I can use. What should I measure.
Are there any aricles for the environment
Any help would be great

SQL Server Performance Stress Test
Jan 11, 2005I have been asked to perform a performance stress test on a SQL server with new hardware that we are going to be receiving.
How have some of you performed your stress analysis against new or existing hardware?
This hardware that I am going to receive will have to be configured within a high availabilty environment. I want to take this opportunity to really put a beat down on this server.
Thank you all for your suggestions.
Memory Stress Test In SQL Server 2005
Apr 2, 2007I have a Windows 2003 Server running SQL 2005. The server has 32 GB of memory and I have enabled AWE in SQL. I have also configured the min and max SQL memory as 1 GB and 28 GB, respectively. However, this server currently has very low activity so I'm not sure whether my AWE-related changes worked. SQLSERVR.EXE process takes up about 100 MB of memory. Is there any tool or scripts that I can use to memory stress SQL to confirm that AWE is really in effect ?
View 1 Replies View RelatedTimeout Exception During Long Running Stress Test
Dec 5, 2006Hi,
We have built two testing apps for sending and receiving files across the network reliably using SQL Express as the database backend. The apps seem to be working fine under light load. However during stress test, we always get the following exception:
"System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."
During stress test, both the sender and receiver are running on the same machine. Sender creates file fragments, store them in the sender database and then send out to the network. File fragments will be deleted from the sender database when the sender receives acknowledgement from the receiver. On the receiver side, file fragments will be stored in the receiver database as they are coming in from the network. Corresponding file fragments will be deleted from the receiver database when a complete file is received.
There is maximum of about 1500 updates and 1500 deletes per second on the sender database. On the receiver side, maximum is about 300 updates and 300 deletes per second. Our goal is to send 30 GB of data (it should run for about 10 hrs). As said before we never have a good completed test run, a "timeout" exception is always thrown from the sender app (when it tries to end a transaction). It could happen as early as 1.5 hrs after we started the test. Note that although we are sending 30 GB of data, but at any point in time the database shouldn't be too big (should be well within 4 GB limit) because we delete file fragments relatively soon.
Next we changed the "Query Wait" setting in the Management Studio Advanced setting from the default "-1" to a very big number, then we have a successful run of sending 30 GB of data.
- First of all, are we not doing this properly in terms of dealing with SQL Express? Is SQL Express able to handle long running heavy load transactions for hours?
- We also noticed even before we got the timeout exception, the memory usage of sqlserver.exe keeps growing. Maybe it doesn't have a chance to cleanup internally. If the app hammers SQL Express for hours, I wonder how does it handle fragmentation? I assume it needs some sort of de-fragmenation, otherwise performance will degrade significantly...
- Seems like the Query Wait setting plays an important role here, any guideline on how to pick a reasonable value? Or should we pick a relatively small number and then do re-try in our app when we get timeout exceptions?
- Is it possible that we are running into some SQL Express resource limits? Any idea of how can we tell other than the VM size of sqlserver.exe?
Any help or suggestions would be greatly appreciated!
Thanks very much

SSIS Foreach Loop Stress Testing Problem.
Mar 2, 2006I am currently working on a project which needs to load over a 1000 xml files. The files are stored across 10 subfolders. I am using a foreach loop with a file enumerator, which is configured at the top of the folder structure and traverses the subfolders. This loops through the files, load the data and then moves the file to another folder. The package executes fine for a few 100 files but then hangs; this happens after a different number of processed files each time the package is run. While trying to resolve the problem we ran performance counters and noticed that the number open handles increased significantly just about the time Dtexec looked like it had hanged and DTexec also then started taking a lot of the cpu processing time. Has one else come across similar situations?
