hi,
I ran into a situation that if I don't use sql server for a while, in MS SQL Server Management Studio, when I run some query again, it takes a long time to respond. I looked into it with Activity Monitor, seems like the query was waiting for something, in the process view tab, it shows that:
WaitType: LATCH_EX
Resource: LOG_MANAGER(112F88C8)
What is the latch-ex? What should I check next to find out the problem?
Thanks.
Hi
I have Problem, My response time is too Low. Is Any one Know how to improve my response time. My DATABASE SIZE IS 11 GB. I didn’t change any configuration parameter after installing SQL Server. Right my server Having default configuration parameters. Whether I have to change any parameters or not. My queries will generate lot of temporary tables.

At my location we are running Great Plains on SQL server with the Great Plains client on the front end communicating over IP Sockets. Occasionally the client will stop responding for up to 15 minutes. This occurs to all clients at the same time. While this is happening I have ran performance monitor on the SQL server using the SQL counters and everything looks fine. Performance on the server and the network does not degrade. Only the Great Plains client is affected. From this I feel this is not a network problem. I would like some suggestions on what could possible cause this type of problem. I am really just looking for a starting point on where the problem may be originating from. Any suggestions will be greatly appreciated.
thanks.
Here is the configuration we have at our site:
64 bit virtual server - Clustered 64-bit SQL Server 2005 Standard SP2 listening on port 1433.
32 bit virtual server - 32-bit application that connects to above SQL Server 2005 via standard OLEDB driver installed with windows (String utilized: Provider=SQLOLEDB.1;Persist Security Info=False;Initial Catalog=applicationdb;Data Source=ServerInstanceName).
We are experiencing a slow reponse of 45 sec to more than a minute on a simple select statement on a table having 5000 rows.
The same select statement on the Server locally in Studio returns results back in 2 seconds or less. But from Stuido on any other desktop (remote) it takes 45 secs or more. Same slow response is seen by the application which is using OLEDB.
I've looked into some of the Server parameters but didn't find any clues.
Any help is greatly appreciated.
Hi all,
I have a website www.searchcontracts.com which has a search feature on the front page. The problem is that whenever a search is submitted (without and filters) it processes extremely slow (if at all, sometime throws 'general network' errors). If working properly it will return about 500+ records. As far as i know if there should be no issues returning a recordset of this size. I have the site hosted in a shared environment and it uses a SQL2000 db. If you filter the search resutls, it's more reponsive (still fairly slow).
If you believe that the hosting server i'm using should be upgraded, what would be the best solution? Keep in mind that i want to be able to return way more than 500+ records in one go.
Thanks

I am working with a client that after every reboot of there SQL 2000 DB server, they experience slow response time for a couple of hours. The server has 12 GB RAM and a Dual 3.8 processor. It is believed that the slow response is due to as queries run after the reboot, they are re-building information in memory and after the memory is built up, it goes back to the normal performance utilizing the memory for speed. Is this an accurate assumption or is there something else to be looking at after the server is rebooted?
Thanks,

Hi
i had a problem with the SSIS response time - its very slow.

Hello,
I have 2 servers (say MAINSRV e SECSRV) running SQL2000 Standard SP3 on Windows 2000 Advanced within a NT (!) domain and each server is linked to the other.
My problem is that if I run a query returning few dozens of rows like:
SELECT * FROM MAINSRV.DbName.dbo.TblName TBLA
WHERE Fieldx = 'anyval'
from a client connected to the SECSRV server, it takes something like 35 minutes to complete, while the same query completes in no time when run on clients connected to MAINSRV.
Even the simplest SELECT Count(*) FROM... takes more than one minute from SECSRV while completing in a fraction of second from MAINSRV.
I tried to change the linked server security options (SQL/Windows), but the remote query remains slow.
There are no locks active on the table, both the servers have almost no load (CPU less than 10%, when tested) and the query returns just a few KBytes, so communication overhead will not be the problem.
Any suggestions will be very appreciated, thank you!!!
Hello.I have a slow response with a system that I am setting up. The OS isWin 2000 Server with SQL Server 2000. My first execution of the SQLprocedure is slow (about 40 seconds), while the second execution isfaster (approx. 3 seconds and what I expect).Using query analyser I can leave the window up and come back ( aftersay 10 minutes ) and my next response is will be slow (and fasterstraight after this).The query itself is the "TOP 10" rows from a table of a remote DB (MSDE2000 - NT station).This is similar to;---------------------DECLARE @SelectRowsFromRemoteDB NVARCHAR(400)SET @SelectRowsFromRemoteDB = "SELCT a.* FROM OPENROWSET('SQLOLEDB', 'Remote', ....) a"EXEC sp_executesql @SelectRowsFromRemoteDB---------------------The CPU usage goes high (with Task Manager), but oddly the task withmost usage is the "Idle Process".Please help with an answeror a good starting point to known where the resources are being used.Regards JC.....

I have a problem with querying systemjobhistory data. Response time is slow and it is vary from time to time, sometime it takes few seconds and sometime it takes more than 2 minutes. I understand that there is quite a number of jobs in DB server and which might result in slow response time.
Is it possible to shorten the response time? like using index? My application is always look like hang when the query take very long time to run.
Any help is greatly appreciated. Thank you.

I am having an issue with the login time from my program to authenticate through the SQLExpress. I have the latest version and I am using for code this :
Dim cnn As New SqlConnection(Globals.m_con_str)
Dim cmd As New SqlCommand("star_login", cnn)
cnn.Open()
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.AddWithValue("@UName", txtUN.Text)
cmd.Parameters.AddWithValue("@PWord", txtPW.Text)
Dim dr As SqlDataReader
dr = cmd.ExecuteReader()
If dr.HasRows Then
While dr.Read()
..........execution of successful login
end while
end if
If cnn.State = ConnectionState.Open Then
cnn.Close()
End If
My issue is this. Once you have done this once speed is good from there on out. After you log out of the program, the login is good. I have tried reindexing because I though this might be the issue but it did nothing.
Any help would be greatly appriciated
I have a windows forms application that runs on my PC that populates a SQL Server Compact 2005 database and then transfers that .sdf file to my mobile device. The communication between the mobile device and PC is done using the Desktop RAPI class from OpenNetCF (http://www.opennetcf.com/FreeSoftware/DesktopCommunication/tabid/90/Default.aspx)
Anyway, I was previously using SQL Server Mobile 2005 and my populated .sdf was around 1.7 MB and I could transfer it to my mobile device in a minute. Once I switched to SQL Server Compact 2005, the transfer process began taking 3 minutes with a 1.5 MB .sdf file. The SSCE also got bloated more easily so I added in the Compact operation each time after I fully populate the SDF to keep the file size at 1.5 MB, but even then it still takes 3 minutes.
I've done a few tests where I simply switch between the two database versions and that simple switch of the version changes the transfer time. I am dumbfounded trying to figure out what the cause might be. Since it is just a file transfer, why would the version even matter unless somehow SSCE is really not compacting and lying about its actual size.
Has anyone run into anything similar to this or may have any ideas what might be going on?
Thanks.

It's to slow when I handle XML field in SQL 2005!
I find that it's slow when I handle XML field (maybe only stored 200kb date) in SQL 2005! Especially when I insert a sub tree to XML field !I have indexed the XML field.
Is it possible that the XML field is not ripe in SQL 2005 database?

Hi!
I have a SQLServer 2005 running om a 64bit cluster. It is used to run a SharePoint 2007 portal. My problem is that the access to the database from the other servers in the farm is very slow.
I made a test program in C# that creates a standard .Net sqlConnection and runs a simple query 100 times. When run on the database server it takes less than a second, but when I run it from the web frontend server it takes 30 seconds. It never fails, it's just slow. The network connection is fast when copying files etc.
I see nothing out of the ordinary in the event log.
Do any of you have an idea what might be the problem or know how I could try to find the problem?
Thanks!

I've just moved a website/database application from windows server 2000 and sql server 2000 to windows server 2003 sp2 and SQL 2005 Express SP2. Database intensive pages now take about 40 seconds where before they took 2-3 seconds.
Things I've tried that haven't helped...
- I changed the ADODB connection string
from: sCnString = "dsn=mydsn;Database=mydatabase;uid=myuid;pwd=mypassword"
to: sCnString = "driver={SQL Native Client};server=myserverSQLEXPRESS;Database=mydatabase;uid=myuid;pwd=mypassword"
- Checked that autoclose is false.
What else can I look at?

Hi,
I have got an application running which connects 2 databases and performs an action that copies data from one database to the other database.
When using SQL Server 2000 MSDE, it takes about 5 seconds.
When using SQL Server 2005 Express Edition it takes about 30 seconds.
For testing 2005, I use 'upgraded' databases, so same indexes and data. I tried reindexing the databases, but always get the same result.
My setup string for installing SQL Server 2005 Express is :
/qb ADDLOCAL=ALL INSTANCENAME=DBNAME SECURITYMODE=SQL SAPWD=QWERTY SQLACCOUNT="NT AUTHORITYSYSTEM"
The code (ADO) is something like :
SELECT FROM original database
-- do something with data
INSERT INTO other database
Until EOF
Any idea how to solve this ???
P.S. When perfoming a simple Query on the databases (with 1.000.000 rows result) with SQL Server Management Studio Express, I see 37 seconds for SQL Server 2000 and 33 Second for SQL Server 2005. That is more the result I expect.

i was using sql 2000, the database contains 500+ tables, 3000+ sp.
i moved to sql 2005 and found problem on generating script (right click database -> tasks -> generate scripts).
i need to generate the table relations.... it is very very slow compared to sql 2000 which is done in about 30 seconds to few minutes.
i already tried many ways including set options to false which in my thought could speed up a lot...but still very slow.
average generate script time with sql 2005 (sp 2): 70-90 minutes.
average generate script time with sql 2000 (sp 4): 2-3 minutes.
can anyone tell why ? thx in advance
Hello,
We have log-shipping set up between a source and 3 destination SS 2000 databases. Two of the destination servers actually perform their log restores across the network from the other secondary server. This allows us to only copy the files once from a remote location. All three servers stay caught up within 15 minutes of each other.
Recently, I added a fourth server to this that has SS 2005 SP2 (X64). I wrote a stored procedure that restores log backups from the same single location as the maintenance plan jobs. The problem that I'm experiencing is that this fourth server is not keeping up with the other three. It seems to take longer to restore the same log backups. The destination servers are all on the same domain. This fourth server was previously part of the same maintenance plan configuration as the others prior to rebuilding it for SS 2005 SP2 (X64). During that time, it stayed caught up with the other servers. There is another database on the new server that I am log-shipping to in the same manner and it stays caught up, though, for the most part, the log backups are smaller. There is a file on the fourth server with a ckp extension for the database in question that doesn't seem to exist for the other databases on this server and the other servers.
Any information on this behavior would be appreciated.
Hi
Here is the brief to my problemWe had our database on SQL Server 2000 and Windows 2000.This machine
had 2gb of RAM and dual Penitum 3 processors and about 25-30 users were
connected all the time. The size of database is around 2 gb. Even on this setup
rate of data retrival was good, never had any issues. We moved to SQL Server 2005 and Windows 2003. This machines has
2 Pentium Xeon 3.4 processors and 2 stick of KINGSTON 1024 MB 333
MHZ DDR DIMM ECC CL2.5 DUAL RANK X4 INTEL. The rate of data
retrival is awful and its very slow. It using about 1.7 to 1.9 gb of RAM all the
time. Page File usage is about 2.07 gb and Virtual Usage is about 1.7gb.I dont quiet understand why is it so slow to get data. We use bespoke software,
so nothing has changed there. Hardware specification of our server is far more better then the recommended
system requirement for SQL Server 2005.Am i missing something out or i havent set up the SQL Server properly? Any help would really be appreciated.Mits
Hi,
Recently our database has been migrated from SQL 2000 to SQL 2005 on a new server(machine) with windows 2003(previously windows 2000). If the database is retained on the same machine but with a named instance of 2005, the application(websphere 5.1) is behaving normal whereas if i configure the aplication to the new server it is running slow for some of the queries but not all.
This change will have to be implemented in production very soon. Any advise will be of great benefit
Thanks

Hello
we have two SqlServer 2005 in cluster. The machines act very slow (although the CPU load is low) as soon as we achieve one of these operations:
- drop / create database
- restore database
We achieve those operations through the SqlServer Browser or via sqlcmd.
Everything else is running smoothly.
Is there any known reason on why it can be so slow ?
best regards
Thibaut
(hope this is not too OT, but could not find any cluster-specific forum).
Sql 2005 Express with XPP SP2 and the latest MS updates sometimes runs very slow.
A SELECT which should take a fraction of a second can take several 10s of seconds.
I have checked autoclose is OFF for database using
use master
go
exec sp_dboption 'your_db_name','autoclose'
And it is definitely showing as OFF
I've looked at the Activity Monitor and when stalled it shows one or two processes for my database which are sleeping with 1 or 2 open transactions. When I look at their details they are simple select statements.
Often when my computer should be idle SqlServer.exe can be consuming 20 - 30% of cpu
I've noticed that I have TWO sqlservr.exe showing in my Task Manager, Processes display
One sqlservr.exe is 27K using about 17% even tho computer is idle has username NETWORK SERVICE
Other sqlservr.exe is 343K using 0% has user name SYSTEM
I don't know why.
