PageIOLatch Slowing Server To A Halt
Oct 2, 2007
We're having problems with our SQL 2000 SP3 standard server (on Win 2k3). Our quasi-data-warehouse application does data processing on feeds of approximately 7 million records. Once the data is loaded in the queries against that data and updates against large tables will often wait with PAGEIOLATCH_SH contention. To give an example, over 7 million rows I was testing something out in development and issued: UPDATE <Table> SET <VarcharColumn> = null, which took forever (over an hour) with the PAGEIOLATCH problem....meanwhile someone else using another database was completely blocked from making an update during that time. It seems like something is very wrong.
The server has 4 drives spinning at 15k rpm with some sort of a high end raid controller, so I'm sure it's not a slow i/o subsystem.
Has anyone experienced this behavior before? Is this an issue that's resolved in 2000 SP4?
Thanks in advance,
-Mark

I'm running into an issue when developing a clr project. I open the project to make changes and apparently it hoses up the sql server that I'm connecting to. I'm opening the CLR Project from a mapped drive on another computer. I can't figure out why just opening up the project causes the slow down. Any ideas.
Thanks,
Josh

We have a process here where a ~45Gb is copied from DB1 to DB2 (both on the same server) using the Export Data wizard and choosing the "Transfer objects and data between SQL Server 7.0 databases" - All the defaults are left as is.
Under 6.5 this method took around 24 - 26 hours, now with SQL 7.0 (SP3) it takes about 16 hours. That's great execpt towards the end of the copy it seems to be hogging most of the server resources - although the processors aren't mazed out.
Users of the other databases are having queries take 5+ mins when they normally come back in < 5 seconds. As soon as the copy finishes there query time return to 'normal'.
Anyone any ideas on where to start looking or how to analyse this problem.
Thanks in advance.

Hello there,
I have a SQL Server 2000 with a dozen of databases. The databases are rather small (all sum up to 10 GB).
The entire server gets extremelly slow from time to time (lasting a few days when it happens and suddently coming back to normality). A profiler trace doesn't show anything strange (besides a lot of SQL Agent entries).
I pretty much tried to isolate every single application that makes use of the databases in that server and see if it was the cause of the problem, but I couldn't find any correlation.
I know the computer where this server runs is quite fragmented. Is there any way I could make sure this is the cause of my performance issues?
I don't know if this might help, but once the server simply went down for some 3 hours, and I wasn't able to bring it up in any way. It eventually started working again by itself. The only thing I did in the meantime was to run DBCC CHECKDB a few times, always getting the response "No errors found on the database".
Any hint on that?

The server being used is a Intel Xeon E5310 Clovertown 1.6GHz 2 x 4MB L2 Cache Socket 771 80W Quad-Core 2U Passive Processor.
The problem is that this server is slowing down everytime about 1000 users log into a forum which the server is running. I think that the server should be able to handle this many users with no problems but I am not sure if that is the case.. The problem is probably something to do with the SQL of the server I am guessing. The server is not mine but I want to help the owner of the server as well as the users who are trying to access this forum but cant because of this server issue. If I was able to get the SQL would I be able to fix this problem? I doubt you need this but the server url is www.smashboards.com
I am fairly new to servers and have never really set one up myself yet. Forgive me for my lack of knowledge about them.
-Thank you!

Hi everybody,
I have a query slower in SQL Server 2005 than in SQL Server 2000. I have a database in SQL 2000, I put it on the same server, but with SQL 2005 and the query take 5 seconds instead of 0 seconds. The DB compatibility is SQL Server 2000 (I tried with 2005 and result is the same). Execution plan seems right and I tried to change some DB options without results. It is weird, when I remove left join on MandatsEx, it take 2 seconds. The view currentEmployeeLevelHistoric returns 45 000 rows and mandatsex has 0 rows.
Here is the sample:
Select ls.EmployeNiveau.pk_EmployeNiveauID as NoNiveau,
IsNull(nullif(ls.Traduction.Description, ''), ls.TraductionDefaut.Description) + ' (' +
ls.currentLevelHIstoric.NoNiveau + ')' As Nom,
ls.currentEmployeeLevelHistoric.DebAssign As DateAssignationDebut,
ls.EmployeNiveau.assignmentReason As AssignmentReason,
ls.currentEmployeeLevelHistoric.FinAssign As DateAssignationFin,
ls.MandatsEx.noDossier, ls.MandatsEx.pk_MandatID,
'' As Period, ls.currentEmployeeLevelHistoric.NiveauPrincipal,
ls.currentEmployeeLevelHistoric.pk_emplNiveauHisto_Id,
ls.EmployeNiveau.fk_NiveauID_Niveaux, ls.EmployeNiveau.No_Ent_leg,
IsNull(nullif(TradPere.Description, ''), TradDefautPere.Description) + ' (' + NiveauPere.NoNiveau
+ ')' As NomSup,
ls.EmployeNiveau.No_Ent_leg + ls.EmployeNiveau.no_divisio + ls.EmployeNiveau.no_sec_eco +
ls.EmployeNiveau.no_etabli + ls.EmployeNiveau.no_mat as employeeScope,
case when ls.mandatExternalisation.fk_mandatID_MandatsEx is null then 2 else 1 end as
ContractCategory
From ls.currentEmployeeLevelHistoric
Inner Join ls.EmployeNiveau on
ls.currentEmployeeLevelHistoric.pk_EmployeNiveauID = ls.EmployeNiveau.pk_EmployeNiveauID
Inner join ls.currentLevelHistoric On
ls.EmployeNiveau.fk_NiveauID_Niveaux = ls.currentLevelHistoric.fk_niveauID_niveaux
Left Outer Join ls.TraductionDefaut On
ls.currentLevelHIstoric.fk_TraductionID_TraductionDefaut = ls.TraductionDefaut.pk_NoTraduction
Left Outer Join ls.Traduction On
ls.TraductionDefaut.pk_NoTraduction = ls.Traduction.No_Traduction and

I bet every SQL-Server guy in this forums has fought pageiolatch issues from one time to another. Either bad indexing, overloaded disks / controllers etc. I know I have, with a great variety of systems and solutions.
Anyways.... I simply have to ask for any of your experiences, as I'm currently stuck with a Navision client, that ocassionally stalls on pageiolatch on even simple queries.
User selects a customer account, asks to see his / her details, scrolls up and down a bit, and whammo, stall, and pageiolatch appears on the server.
Something tells me that this might be an ODBC driver issue rather than actual sql-server issues. Fetching the initial data isn't the issue, but scroling back and forth in the recorsset it seems to cause the cursor to freeze or at least lose track or stall in the progress of paging through the records.
All of the above sounds very unclear, I know, I'm just trying tro track down or center on the problem, so that I might find a solution. So if you have any experiences with clients, cursors and odbc driver version for sql-server, that really make a lot of trouble, let me know.
Cheers, Trin

Hi Guru,After spening quite sometimes to watch my box, I've seen PAGEIOLATCH isa lead blocker in my SQL Server 2000 server. Below is the detailed:SPID lastwaittype waitresource blocked status cmd57 LCK_M_S KEY: 7:963690681:8 65 sleeping execute65 PAGEIOLATCH_SH 7:1:217904 0 sleeping selectI thought, latching should be very short-term synchronization. Fromsystemprocess table, I saw the latch waited in a minute sleepingwithout doing any work.My database is about 23GB and more than 5000 tables. The RAID subsystemis RAID1 with 1 disk mapped to C and D logically. Data files and tempdbfiles are located in one location. Tranlog file and log backup filesare located in the same location with different disk spindle.Currently, we are experiencing very slowness and IO bound. I'm ready torebuild the server by putting the RAID10 and 1 and distributingmultiple data files to different RAID10 and tempdb and log files toRAID1.Other than this, how to minimize the IO latch contention?Thanks so much,Silaphet,

Hi,I have an app that imports alot of info from alot of files, processes it and stores it in a SQL database. It works fine except for the fact that if tries to import to much information (about 50000 lines) the whole machine grinds to a halt. It processes the first part quickly enough but then gets progresively slower untill its at a stand still. Could this be due to:a) the fact that I read from several different files ; do I need to free up the memory assciated after closing 1 file and opening another.b) I have over 3000 tables ; is this mad? should I restructure?c) I do many thousands of inserts; Are there memory freeing issues I need to be aware of? Thanks for any helpDan

Is there a way to continue the execution of a script after an error occured after a BULK INSERT execution?
I tried this but is not working:
ex:
declare @m_strSQL nvarchar(4000)
declare @m_RetCode int
select @m_strSQL = N'BULK INSERT DBName.[dbo].[tableName] FROM ''c:FileName.txt'' WITH (CODEPAGE=''ACP'')'
execute @m_RetCode = sp_executesql @m_strSQL
if @m_RetCode > 0
print 'error'
else
print 'no error'

the following test script works fine and displays a list of cars from the fairly small database, but if I specify the sort order in the querystring, the page takes ages to display and usually times out.

I've been doing some experiments with speeding up copying tables ofapproximately 1 million rows between databases using BCP and BULK INSERT.I noticed that the total time for removing the indexes (non-clustered) andthen recreating them after the BULK INSERT was significantly less than justdoing the BULK INSERT with the indexes left there, even though I specifiedTABLOCK.I would have expected SQL Server not to update the index until the insertcompleted (given the table lock) and so removing the indexes would have noeffect. Can anyone explain why removing the indexes should speed it up?This is on SQL Server 7.CheersDave

In SQL Server Profiler, I see the following SQL statements with durations of 2000 - 7000:
select top 1 keywordID, keyword, hits, photo, feed from dbo.XXXX where hits > 0 order by hits
and
UPDATE XXXX SET hits=1906342 WHERE keywordID = 7;
Where the hits number is incremented by one each time that is selcted for that keyword ID.
Sometimes these happen so frequently the server stops accepting new connectinos, and I have to restart the SQL server or reboot.
Any ideas on why this is happening?

Hello:
Interestingly enough, I haven't come across this before. I have a SQL stored procedure which takes four parameters; periodstartdate (datetime), periodenddate (end time), hsgradyearstart (int), hsgradyearend (int)
[dbo].[CalculateActivityTotal]
-- Add the parameters for the stored procedure here
@periodstartdate datetime = '2007-01-01',
@periodenddate datetime = '2007-01-08',
@hsgradyearstart int = 1900,
@hsgradyearend int = 2007
AS...
If I run the stored procedure and pass the parameters using EXEC or
sp_executesql "CalculateActivityTotal '2008-01-04 12:00:00', '2008-01-11 12:00:00', 1900, 2008"
the stored proc takes well over ten minutes to run (it does a bunch of aggregation). If I modify the stored procedure to take no parameters, however, and I hardcode the dates in the stored proc using declare and set then it runs in 13 seconds. What could be causing my problem and how I can I go about resolving this? I need to pass the parameters via reporting server. Thanks!

My server is a dual AMD x64 2.19 GHz with 8 GB RAM running under Windows Server 2003 Enterprise Edition with service pack 1 installed. We have SQL 2000 32-bit Enterprise installed in the default instance. AWE is enabled using Dynamically configured SQL Server memory with 6215 MB minimum memory and 6656 maximum memory settings.
I have now installed, side-by-side, SQL Server 2005 Enterprise Edition in a separate named instance. Everything is running fine but I believe SQL Server2005 could run faster and need to ensure I am giving it plenty of resources. I realize AWE is not needed with SQL Server 2005 and I have seen suggestions to grant the SQL Server account the 'lock pages in memory' rights. This box only runs the SQL 2000 and SQL 2005 server databases and I would like to ensure, if possible, that each is splitting the available memory equally, at least until we can retire SQL Server 2000 next year. Any suggestions?

Hi,
We have an old machine which holds SQL server 2000 database. We need to migrate a whole database to a new machine which has SQL server 2005.
When we tried to move whole database using Import and Export Wizard, only tables can be selected to import/export. However we want to import/export the whole database, including tables, stored procedure, view, etc. Which tool should we use?
Thanks.

When I proposed start to use SQL Server 2005 for new VS 2005 web sites, one of my co-workers responded that
we will update the old SQL Server 2000 databases to SQL Server 2005 when we are ready to use 2005 SQL Server.
Questions:
1. Any expected problems to upgrade old 2000 databases to new 2005 SQL Server?
2. I have installed both 2005/Management Studio Express and 2000/Enterprise Manager in my PC. Any expected
problems when running both 2000 and 2005 SQL Server at the same database server?
3. What is the best configuration for running SQL Server 2005 when we have old 2000 databases? Upgade or not upgrade?
TIA,
Jeffrey

Hi,
I am having a problem connecting my .net applications from the application server to the database server. When I run the application from my windows xp (sp2) box it works fine. When I try to connect via SQL Management Studio to the database server from the application server I get the same error.
Here is the error:
System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Here is the Environment:
App Server:
Windows Server 2003 Standard Edition
Inside Company's Firewall/ Network
Database Server:
Windows Server 2000 Advanced Edition
SQL Server 2000 SP4
Remote Connections to the Server is checked
Enable Protocols: Named Pipes & TCP/IP
TCP/IP Port: 1402 (I don't know why it isn't the default of 1433)
The db server is sitting out side the Company's firewall (don't ask me why). I can access it fine from inside the firewall on my XP box but not from windows server 2003. There is a web server outside the our network that also connects to the db server with no problem and that is running Windows Server 2003 Web Edition.
I can ping the db server from the app server using the IP address.
I tried using the IP address and the port 1402 in my connection string but that didn't work from any machine (XP and Server).
I imagine the issue is somehow related to the company's firewall but why would it only block Windows Server 2003 and not XP?
What do I tell the network admin to change?
Any help would be appreciated.
Thanks,
Oran

if you can restore a database to Server B using Server A as the service. Meaning we would issue the command on Server A but somehow point to Server B as where we want the restore to happen.
The backup file would be in a location independent of both servers.

Dear all,On Win2000 server with SP3, I am trying to access a SQL Server 7.0database, "TestDB", from VB6 via a SQL Server ODBC system DSN using ADO2.7. In SQL Server Enterprise Manager, there is a login named "Tester".In its property window, NO "Server Roles" was assigned but its"Database Access" was set to "TestDB". This login was also made as theuser of "TestDB" with "public", "db_datareader" and "db_datawriter"selected as its "Database role membership". All the tables I am tryingto access in "TestDB" were created under "Tester".My code is like:Set conn = New ADODB.Connectionconn.Open "DSN=TestDSN;UID=Tester;PWD=test"Set cmd = New ADODB.Commandcmd.ActiveConnection = conncmd.CommandText = SQLset rs = cmd.Execute()If I set the SQL to something like "SELECT * FROM tbl_test", I alwaysget an error of "-2147217865" saying "[Microsoft][ODBC SQL ServerDriver][SQL Server] Invalid object name tbl_test". If I set the SQL to"SELECT * FROM Tester.tbl_test", everything runs properly. Could anyoneplease kindly advise why the first SQL is not working? Or in otherwords, why must I prefix the table name with its owner while the DBconnection is already made under that owner name? Thanks in advance.Tracy

When I try to migrate a database on a SQL Server 2000 server to a SQL Server 2005 server with the Copy Database Wizard of the SQL Server Management Studio, I'm confronted with the following problem;
Performing operation...
- Add log for package (Success)
- Add task for transferring database objects (Success)
- Create package (Success)
- Start SQL Server Agent Job (Success)
- Execute SQL Server Agent Job (Error)
Messages
* The job failed. Check the event log on the destination server for details. (Copy Database Wizard)
When I take a look at 'Event viewer' on the SQL 2005 server, the following error is displayed;
InnerException-->An error has occurred while establishing a connection to the server.
When connecting to SQL Server 2005,
this failure may be caused by the fact
that under the default settings SQL Server does not allow remote connections.
(provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
I already enabled the MSSQLSERVER network configuration protocols (TCP/IP and Named Pipes ).
How do I solve this problem?

My site works fine in VWD2008 express, but I get this error when I try to use it on my live website.
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
According to this article: http://support.microsoft.com/kb/914277 I am supposed to:
1.
Click Start, point to Programs, point to Microsoft SQL Server 2005, point to Configuration Tools, and then click SQL Server Surface Area Configuration.
Ok, there is no such program in this folder. The only thing in there is "SQL Server Error and Usage Reporting"...
The other thing I am greatly concerned with is this: All is want is for my webpages to be able to access my database for user authentication. I DO NOT want to grant the internet rights to remote connect to my database.

Hi Guys,
I have had SQL Server Express and Sql Server Management Studio Express installed on my machine for some time and recently tried to install a trial of SQL Server 2005 as well. (Yes, I'm migrating from Visual Studio Express to Visual Studio Professional, just as in tended!)
Everything went fine except that nothing seemed to be installed. I searched in all the obvious places - both on the Start/Programs menu and on the hard-drive: nothing.
A check under Add/Remove Programs showed that Sql Server 2005 Express was installed, but called SQL Server 2005.
So after a number of retries in which the install program kept saying that there was nothing to install, I selected every option under Advanced in the intall process. This resulted in stuff being installed and I now have SQL Server 2005 running on my machine, but no SQL Server Manager icon.
My questions are:
Where can I find the SQL Server Manager executeable?
Has anyone installed SQL Server Express, SQL Server Mangement Studio Express, SQL Server 2005 and SQL Server Management Studio on a single machine successfully? If so, what order did you install them in? (I'm planning on uninstalling everything SXQL Server related and starting again.)
Thanks very much for your help.
Regards
Gary

Hi
I have created a linked server from SQL Server 2005 (SP 1) to SQL Service 2000 (SP 4) with a sql server login that is available on both servers but with different passwords and permissions.
I am getting the following error while accessing the linked server in management studio based on the scenario given below ;
------ Error Message Starts
OLE DB provider "SQLNCLI" for linked server "(SQL Server 2000 instance name)" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote host.
Msg 18456, Level 14, State 1, Line 0
Login failed for user 'abc'.
------ Error Message Ends
Consider login name is abc.
Now this login abc has sysadmin rights on sql server 2005.
The same login abc has only db_datareader rights on sql server 2000 on just one database and is not associated with any fixed server role.
I have configured the linked server using the following options;
1. I have tried impersonating login from SQL Server 2005 to SQL Server 2000 .
2. I have also tried specifying remote login / password option.
Anyone having any idea, would be of great help.
Regards,
Salman Shehbaz.
