Sudden Large Slowdown At Random Times
May 4, 2007
We have an application in which one particular stored procedure goes from .3 second response times to 20-40 second response times, suddenly, at seemingly random times of the day. Recompiling that particular stored proc fixes the problem temporarily.
The 3 main tables have between 500K and 1.5M records, are defragged daily and contain the past 42 days of work. Old records are deleted once daily. The slowdowns do not conincide with the deletions, occuring without a clear pattern. Nothing else on going on on that server -- it is dedicated to this one app. Nothing shows in event log. It is clustered Windows 2003, with SQL Server 2005 RTM version. SP2 of SQL2005 due for an install next Monday. This behavior also was seen when the app was on a different server running SQL2K SP3, so think the underlying problem is some sort of design issue with the app, not a SQL server bug. Has anyone seen something like this and what suggestions do you have for doing a permenant fix? Think that a recompile of the sp causes a new execution plan, but why would that be necessary daily or even several times a day? 30-50 users are banging away at it. The app is an order entry system. The tables contain what are basically order histories and label data. Am running out of good ideas. Thanks for any help.

Hello,
I need to sample data in a very large table in SQL Server 2000 (a gazillion rows of Performance Monitor statitics).
I'd like to take the top 5%, for instance, based upon a column containing random numbers.
Can anyone suggest a highly efficient method of populating a column with random numbers.
Thanks in advance.

The following (VB.Net) code causes exceptions at seemingly random times.
Any suggestions?
Not sure if the problem is in .Net's ODBC support or in Sql Native Client.
If MARS is off, usually after less than 100 loops:
Code Snippet
System.Data.Odbc.OdbcException was unhandled
ErrorCode=-2146232009
Message="ERROR [HY000] [Microsoft][SQL Native Client]Connection is busy with results for another command"
Source="SQLNCLI.DLL"
Turning MARS is on bypasses that error, so it will sometimes survive a thousand or so runs before hitting:
Code Snippet
System.Data.Odbc.OdbcException was unhandled

Code here:

daTemp.MissingSchemaAction = MissingSchemaAction.AddWithKey
daTemp.Fill(dtTemp)
Dim cbTemp As New Odbc.OdbcCommandBuilder(daTemp)
Dim viewTemp As New DataView(dtTemp, Nothing, "Number", DataViewRowState.CurrentRows)
Dim i As Integer
For i = 1 To 1000
Dim test_number As Integer = CInt(Rnd() * 2000)
If viewTemp.Find(test_number) = -1 Then 'Keep it unique
Dim new_temp_row As DataRowView = viewTemp.AddNew()

testcmd2.ExecuteNonQuery()
testcmd2.Dispose()
testcmd2 = Nothing
'connection.Close()
'GC.Collect()
'Console.Write(".")
run_count += 1
End While
End Sub
End Module
Usually the ".Update" triggers the exception, but sometimes the other sql commands do it.
Have tried various experiments with disposing of objects immediately when finished, but no effect.
Opening and closing the connection each loop seems to delay the errors, but it still happens eventually.

I have a production sql 2000 box with 24 gig of memory running 3rd part app. There is a posting process (takes all the orders and does the math). Before we did the upgrade it was a 15-20 minute process. Nothing has changed, but in the last month it has gone 60-75 minutes. There were also some windows updates applied (win 2003 adv server). I realize looking for the needle in the haystack, but has anyone seen this issue with either the sql sp4 or windows SP for 2003?

The strangest thing happens after upgrading to SQL Server 2005 64bit (4 cores, 16G RAM)
A table base function call that usually returns instantly would slow down to 25secs!
The underlying data is unchanged.
Now, if I reload the function (run alter function but without any changes to the function) the performance is restored for a while, but in about one week it slows down again.
Two questions:
1. most important: is there anything I could do to preemptively restore the performance? Like running a dbcc statement every night?
2. what is the cause of this slowdown?
Any suggestions welcome

Hi,I need to extract randomly 5 records from the table "Questions". Now I useSELECT TOP 5 FROM Questions ORDERBY NEWID()And it works. The problem is that I need an additional thing: if SQLextracts record with ID=4, then it should not extract record with ID=9,because they are similar. I mean, I'd like something to tell SQL that if itextracts some questions, then it SHOULD NOT extract other ones.How can I do it?Thanks!Luke

If I remove the TOP 200 this query returns about 2.5 million rows. It combines a lot of records and turns it into much more programmer friendly results. The query slowed down from 2 seconds to about 13 seconds as it has grown from about 10k to the now couple of million.
Code Block
SELECT TOP 200 *

(
SELECT
[UserProfile].[UserId]
,[aspnet_Users].[UserName]
,[City]
,[State]
,[RoleName]
,[ProfileItemType].[Name] AS pt_name
,[ProfileItem].[Value]
FROM
[UserCriteria]
,[aspnet_Users]
,[aspnet_Roles]
,[aspnet_UsersInRoles]
,[Location]
,[ProfileType]
,[ProfileTypeItem]
,[ProfileItem]
INNER JOIN [UserProfile]
ON [ProfileItem].[ProfileId] = [UserProfile].[ProfileId]
INNER JOIN [ProfileItemType]
ON [ProfileItem].[ProfileItemTypeId] = [ProfileItemType].[ProfileItemTypeId]
WHERE [UserProfile].[UserId] IN (
SELECT [UserCriteria].[UserId]
FROM [UserCriteria]
WHERE
Zipcode IN (
SELECT [Zipcode]
FROM [ZipcodeProximitySQR] ('89108' , 150))
)
AND [UserProfile].[UserId] = [aspnet_Users].[UserId]
AND [UserCriteria].[UserId] = [UserProfile].[UserId]
AND [Location].[Zipcode] = [UserCriteria].[Zipcode]
AND [aspnet_UsersInRoles].[UserId] = [aspnet_Users].[UserId]
AND [aspnet_UsersInRoles].[RoleId] = [aspnet_Roles].[RoleId]
) AS t
PIVOT
(
MIN([Value])
FOR pt_name IN ([field1],[field2]],[field3]],[field4]])
) AS pvt
ORDER BY RoleName DESC, NEWID()
The line: FOR pt_name IN ([field1],[field2]],[field3]],[field4]]) I change the values from the long names to read field1, field2... because it was irrelevant but confusing because of the names.

Here is a link to the execution plan from Microsoft SQL Server management Studio.

There are no table scans, but the Hash Match from the inner join is pretty bad.
Can anyone give me a pointer or two?

Hi,
I am currently working on a report with 3 cascading parameters. These three parameters depend on the datasets whose data are retrieved from a large table with SELECT DISTINCT. As the table grows larger, selecting values for these parameters cause postback, and slow in performance from user perspective. I am looking for a way to reduce postback. Can anyone suggest the way to retrieve the dataset all once and filter the dataset without causing postback? Or any other way to improve the performance will be greatly appreciated.
Thanks,
NL

Hi,
Just a general question here.. I'm designing a web application that might have 50 million - 100 million rows plus. Basically its a simple logging table each row probably only 24 bytes wide, however I can see it taking quite awhile to execute.
The query is basically a group by, showing the amount of "hits" per day.
Are there any special types of strategies I should implement ? Or is a properly designed structure with indexes likely sufficient (on the right hardware of course)
Thanks for any advice!,
Mike

We seem to be having a rather strange issue. We just
finished migrating from 2000 to 2005. I've been working on converting packages
from DTS to SSIS. Everything has been going well in testing, but a problem has
shown up going into production. The first package I deployed ran significantly
slower on the production server, going from about 7 seconds to 90 seconds. The
production server is much more powerful, so this was rather confusing. The
major difference is that the server is running 64 bit.
After searching around, I haven't found much that is helpful. To test things
out, I created a blank package that does absolutely nothing. All it contains is
a single connection manager (OLE DB). Executing this package takes 45 seconds.
If I remove the connection manager, it executes in 0.1 seconds. Setting
DelayValidation to TRUE has no effect. If the connection is to a nonexistent
server, or if an incorrect login is used, the execution time is still 45
seconds. Adding a second connection manager increases execution time to 75
seconds. The package runs on my local computer in 0.1 seconds.
Any ideas what could be going on here? I can€™t believe that
no one would have seen an issue like this. Is there some sort of strange
configuration issue going on here?
Thanks in advance.

I'm using ASP and SQL Serv 2000. What I need to get from 2 tables (company & customers) is random 10 customers from random 20 comp.
Anyone got an idea how to do this??? I've spent 2 days trying to get stored proc. or T-SQL to work, but nothing good came out of it. I can get 1 comp and 10 cust, but not a grouped list of 20 comp. w/ 10 cust. each.
Help is greatly appreciated.

I work for a small analytical laboratory. I'm mostly the net admin guy,
but I do the db stuff (poorly) and other things.
Last night right before closing my users started experiencing bigtime
slowdown. This morning it was magically better for a short duration.
As the day went on the problems got worse.
We use MS Access as a 'front end' to talk to the SQL server. My users
would go into fields and toggle on (or off) something they wanted.
Sometimes the system acted as in the toggle never happend (cant
generate a report without the right options toggled).
I'm not very DB savvy, so I checked all the other things I was having a
problem with that day to see if it was direct correlation.
A few people have suggested I defrag the hdd as well as the SQL db. I
have maintenance plans set up to back up the db and transaction logs
daily (and weekly). However the maintenance plan that had "reorganize
data and index pages" checked has been disabled for 2 months, since it
seems it never finishes. It would run, and then one of my other plans
would run (several hours later on the weekend).. and I'd come in on
monday and find 3 maintenance plans all bound up.
Usually I had to stop the SQL server and re-start it as the 'stop'
option for maintenance plans wasn't being responsive.
At any rate. I'm looking for suggestions. The DB is (after a shrink)
7GB. I don't think is excceptionally large, so I'm not sure why I'm
experiencing these problems.
I found some scripts for DBCC SHOWCONTIG and DBCC INDEXDEFRAG. But I'm
not sure how to execute them in a scheduled fashion? Is this just done
in the maintenance jobs?
My users need to use this system (reliably) asap tomorrow. I'm going in
2 hours before the office opens in hopes of saving the day and anything
I could arm myself with to make this process easier would be completely
awesome.
So with that in mind. I'll stop rambling.
Ah yes, some information regarding the system:
Windows SBS Server 2k3
SQL Server 2000 w/ SP3 (or maybe 4?) (came with SBS 2k3)
Hardware:
AMD X2 4800+
2GB ECC RAM
160GB x 2 Sata Raid config.
1x Gigabit Network Card
(Not connected to the outside 'world' at all).
Thank you for your consideration,
Ryan

I have an asp page that inserts several pieces of input into an SQL database. Page was working fine, and Im not sure what could have changed to cause the following error when data is entered into one of the fields:
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]Line 1: Incorrect syntax near 'room'.
/Global.asp, line 20
where global.asp line 20 is oConn.execute cSql
In this case the text I input was: this room is big
I also tried input of fdsa, and recieved the following error:
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]Invalid column name 'fdsa'.
/Global.asp, line 20
More Details:
The field I am inserting this value into is a (nvarcar(1000),null).
None of the other fields on the page have a problem, and this is the last value insert into the database.
Any suggestions or ideas on where I should look to begin solving this issue.
Thanks!

I am working on a web application at work where we are using a SQL Express 2005 database.
We have 2 environments, my development environment which involves my local machine and VS 2005 Pro, and the database on a seperate server.
The client environment is on another server on another network also running SQL Express.
I was working on Friday, everything was fine and dandy. I was sick yesterday. When I come in today with no code changes (checked SVN) I am now suddenly getting timeout problems.
Error Type:
Database
Message:
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
I thought maybe this was just a problem with my machine so I've checked another development box here, same problem.
Also, the client emailed and they are getting the same problem. Thier environment is using a compiled version of the code from last week. No changes.
Did something happen yesterday or today that requires a patch or upgrade? Why would these failures suddenly appear? What can I do to troubleshoot this?
Thanks,
James

Hi. I recently upgrading my dev machine to Vista and VS 2008 simultaneously (clean install) and upgraded my VS2005 project, which was previously using SQL CE 3.1. Now when I compile and run it, I get a database exception telling me to upgrade my database to version 3.5!
First of all, I tried running the Repair() method to upgrade the database file, but then I get an exception telling me the password is incorrect (it most certainly is not, I didn't change a thing), so it won't even let me upgrade it.
Secondly, I even tried removing the reference to System.Data.SqlServerCe and manually adding the verison 3.1 reference back, but it still for some reason loads version 3.5 instead of version 3.1.
So! Please either tell me how I can properly upgrade my users' database file to version 3.5 and have it work with the latest libraries, or tell me how I can at least use the old libraries like I was under VS2005. The .dll files are all present in the project and I haven't changed them at all, they're being properly copied to the output directory and everything. I even checked the "Specific Version" attribute on the reference in the project, but no help.
Do I have to do something special to tell my application to load the local copy of the assembly as opposed to, say, one in the GAC?

I have been developing a database in SQL Server Management Studio Express for the past few weeks. I have been writing stored procedures and functions, creating and deleting tables, etc., etc. and everything has been working just fine.
Today, however, if I try to run any of the functions I have written I get "Invalid object name 'functionName'."
This occurs even if I create a new function, execute the CREATE statement. Then if I refresh the Functions folder I can see my newly created function, but I cannot run it.
This is terribly frustrating.
Does anyone have any ideas as to what might have changed? I am logging in as the same user, on the same machine that I have always logged in on. I created the database that is giving the error.
When I right-click SQLEXPRESS in the object browser, and go to Permissions in the Server Properties dialog, no permissions are selected as "granted" for my login name under any of the Logins/Roles. (ex. BUILTINAdministrators: my login name is listed in the "Explicit permissions for BUILTINAdministrators" list, but no permissions are granted. If I go down the list selecting [checking] the various permissions, then close the dialog. When I open the dialog again, rows have been added to the list that have the Permission name, then "sa" listed as the Grantor, with that row checked. But, there are still no checks next to my login name.)
The only thing that has changed on my machine, that I am aware of, is that a Windows Authentication update ran on my machine earlier today. I am using Windows Authentication in my SQL Server instance. I assume it has something to do with that.
Please help. This is urgent. We have a presentation on this project in 3 days.
ugh.
Thanks in advance for any help you can provide.

I have a database with tables that are used for various front-ends, Access 97 and ASP. All of a sudden, my "Stores" table will not let me add, edit, delete, insert records. I checked security permissions everywhere and cannot figure out why this is happening. Is there something linked to this that might be running a process that might be causing this?
TIA,
Bruce

I have several databases on a 2012 instance that are mirrored to a second server, and log ship to a third server for reporting purposes.Recently, for two of the databases, the log shipping has been failing at least once per day, and sometimes more often.
i have deleted and recreated both the mirroring and log shipped databases on several occasions, but the problem is still happening.The log shipping restore jobs don't get marked as failed in the job history, but if you expand the history you can see errors such as this:
Date21/11/2013 13:00:01
LogJob History (LSRestore_OAK-DCSQLDB1_OtherCarrierLive)
Step ID1
ServerCHERRY
Job NameLSRestore_OAK-DCSQLDB1_OtherCarrierLive
Step NameLog shipping restore log job step.
Duration00:00:30
Sql Severity0
[code]....
Restoring a new backup of the database cures the problem for anywhere between 15minutes and 12 hours, but it always seems to re-occur.I have run DBCC on the source databases with no errors reported, and five other databases have the log shipping working without errors.

I've got a job that sends out the results of a stored procedure in anemail via xp_sendmail. The job code is as follows:DECLARE @rlist varchar(1000)Declare @Q varchar(100)Select @Q = 'EXEC impact_exec..TLD_Reconciliation'Declare @Sub nvarchar(60)Select @Sub = 'TLD Reconciliation - Condensed Report'SELECT @rlist = 'jmiller@wbhq.com'exec master..xp_sendmail @recipients=@rlist,@query=@Q, @subject=@SubThe error message I get when running this in Query Analyzer is:ODBC error 7410 (42000) Remote access not allowed for Windows NT useractivated by SETUSER.In Enterprise Manager the owner of the stored procedure in question isdbo. Our SQL guru here suggested I change the owner of the storedprocedure from dbo to myself.I did that and got a warning message that changing the owner willbreak connections. (I'm paraphrasing here because I don't rememberthe exact wording of the warning.) Anyhoo, after changing the owner,and then trying to run the code in Query Analyzer I got the errormessage that the stored procedure could not be found.I'm not sure what to do here. I've never seen the error messagebefore. This same query worked just fine a couple of days ago.Any ideas?Thanks,Jennifer

Hi,
We're running a replicationprocess for months now, and 2 days ago it broke down, for no appearant reason I can detect. The setup is this:
A SQL2K server has a publication defined on a database, consisting of several dozen tables. It is a transactional publication, running continuously. There is 1 subscriber, a SQL2005. Both servers run with Win2003 and all have the latest servicepacks.
Up until 2 days ago there was hardly a problem. Then I received errormessages on being unable to load into a specific table. That table had been changed on that day, namely, 1 column was changed from CHAR(13) to CHAR(12). I do not know if this has any relation with the problem we experience.
Currently the databases are structural the same. I could not get the replicationprocess to work and deleted all, publication on server1 and subscription on server2. I tried to setup a new transactional publication, which is not a problem, however, I cannot create a succesful subscription. I receive the message:
The process could not bulkcopy into table 'Tablename', where tablename is the changed table...
Again, both tables in publisher and subscruiber are the same in all respects. When I remove the offending table from the publication, the same message now with another tablename... Removing this table will result in again this message with another tablename...
I am really flabbergasted. Any idea where to look at?
TIA

I've been building and running script tasks for years without issue. Then all of sudden last week Visual Studio starts showing the "Task is configured to pre-compile the script, but binary code is not found" error anytime I open a script -- even I make no changes. If I copy the dtsx package to another machine, the script compiles fine and I can see the binary data in the raw .dtx file -- so I know the code is correct.
I can also reproduce the error simply by adding a new script task, going into "Design Script", make no changes to the default code (which is basically one line: Dts.TaskResult = Dts.Results.Success) and simply press "OK" on the Script Task Editor.
I've been trying to find some VS setting somewhere that might stop the script IDE from producing the binary code, but I can't. It doesn't seem to be project setting, because all my SSIS projects are now suffering this problem on my main dev box.
Anyone experience this?

I have had SQL2005 on a server for a very short period of time. Today I found that I am not able to execute an SSIS package in debug. It give me an error stating that the evaluation period has expired for data transformation services. I went to check the version by querying, but nothing happens when I click on the Server Management Studio link.
Has anyone seen this before or how long the trial version should last?
Does anyone know what version may have been installed on my server?
Thanks,

Has anyone noticed that if you created DTS package and try to
change connection properties (i.e. change DSN or redirect
DTS to different server or Database), as soon you click OK
it does not save new password and hence does not work
anymore. In my case to move Database from Development to
Production server I would have to recreate all DTS packages.
Is there any way around it?
Any ideas greatly appreciated.

I am trying to get random numbers to have a unique value for different processes, then I can identify each process. What happens is that I use rand() function without seed, so I got my random numbers, but after shutting down SQLServer and try to get again another random number after booting up, the same series of random numbers is given again and again. So if anyone knows how I can get unique values,even though reseting the server, and using random function or any other method which automatically provides unique values,I'll really appreciate it if you let me know it.
This is the function: select rand()
Alberto.
