DTS Database Transfer - Slowing Down The Server
May 29, 2001
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.

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'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

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
ls.Traduction.Langue = 1
Left Join ls.MandatsEx on
ls.EmployeNiveau.fk_MandatID_MandatsEx = ls.MandatsEx.pk_MandatID

Hi,
I am new to the database concepts, maybe my questions are very basic.
I transfered data from one sql server to another thru object/database transfer. The transfer was successful, ie.,
all the data was present in the new server too. I am using an application with ASP as front end and SQL server 6.5 as back end.
So i am able to all new records, delete them, update them thru my ASP programs. But, i am not able to update the records
which where transfered from the old server. I hope some one of can help me, as i said earlier i am new to databases,
so give me a detailed solution.
Thanks,

there is applications which were written in FoxPro. Recently it has been redone in SQL.
How can I check that Whether their server designated to host the database is ready and fully up to spec on revs and patches,If not how and who can bring it up.
and How can I determine what else needs to be addressed to ensure a smooth transition and implement?
Define ongoing maintenance requirements.

Hy ,
How can i transfer a database from Access to Sql Server 2000?
Exactly : i want to transfer a .mdb into .mdf, and i want to keep the structure of .mdb, a structure which have tables, queries, macros, modules... When i start the transfer with Data Transformation Services ( DTS- Import Data ) , i can see that DTS shows me only tables and queries. At the end of transfer, in my .mdf database, on server, i have only tables, without queries, macros, modules.
My question is how can i transfer the queries and macros ( exactly how are in .mdb ) to .mdf database?
Thanks in advance for any advice..

Hi,
A question regarding SQL Server 2005 Express edition. Is it possible to export Access databases into SQL databases without using programming (e.g. using SQL and programming languages)?
I understand you can do this with DTS, but the Express edition seems not have DTS.
Many thanks

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

Background
SQL Server 2005 Standard 9.0.1399 64bit
Windows 2003 64-bit
8gb RAM
RAID-1 70gb HD 15K SCSI (Log Files, OS)

8 Clustered Windows 2003 32-bit OS IIS Servers running Asp.net 2.0 websites
All 8 servers talking to the one SQL server via a private network (server backbone).
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!

Transfering DB from one collation in SQL 2000 to a different collation in SQL 2000.
We need to transer our databases from codepage 850 to 1252.
We have succesfully transfered all objects and data EXCEPT stored procedures and triggers using the "Import/Export Data Wizard." We then scripted all the stored procedures and triggers from the cp850 database and installed them into the cp1252 DB. However for quite a few stored procedures and triggers we get the error "Cannot resolve collation conflict for equal to operation." I have tried scripting the sp's with the option 'Only script 7.0 compatible features' on and off but get the same errors each time.
Can anyone help?
Thanks
Paula.
