Our entire sales database sits on an Informix server and users run their reports directly to this server.
Because of the volume of data - upwards of 7 million rows in some tables we are finding performance is becoming an issue. We realise that Informix is not the best for running queries and so are looking to replicate to a SQL server and use that as a reporting server.
My chosen method is DTS using ODBC which works fine. However due to the sheer volume of data to be downloaded each night (over a 512K wan link) we only want to download changed data.
Is there any way we can get SQL2000 to download only change data - i.e a differential download or something? We don't have a unique field in the table (for whatever reason) such as sales date or transaction ID (shops might upload old / back-dated transactions for example due to a systems failure).
If I do have to download all the data every night is my method the most efficient or is there some other approach I could use?
Ultimatly the aim here is to relieve the Informix server of the reporting overhead so any alternative ideas are welcome!
I need to transfer seven tables from Informix DB to SQL Server every night. Any suggestions for the best way of doing it? Is DTS the best way? How about through replication?
I have Informix 9.4TC6 and SQL Server 2005.DB_LOCALE in Informix DB is en_US.utf8 (en_US.57372).First, I created DSN to Informix. Then tried to get data with WinSqltool and it works fine.But when I created linked server in SQL Server 2005 I have problemswith languages other than English.I get a string like:è 'å· åŒ-å|å·¥æ¥æ ªå1/4 ä1/4šç¤3/4It seems to me that SQL Server splits 2-byte characters in 2 1-bytecharacters.If in options of linked server we set Collation Name to exactlanguagewe want --then string data will be correct (of course only oflanguage that we choose).Do you have any suggestions?????????P.S. I don't want to use SSIS (DTS) for extraction from Informix DB
hi guys, i want to use SSIS package to download files from an http website. i am tried using Http connection managers and webservice task but it asking me the wsdl file. i dont know where that file is. can anyone please guide me? or suggest me any other way to do this?
I'm having an error with merge replication my suscriber are downloading old data, all this start happen after I install SP4.
let explaint this with more details ,
if a made an update to a row in a table from the publisher , the agent history show that 1 change have downloaded to the suscriber, a put an audit in the suscriber and yes one update was downloaded but the row still the same, look like the suscriber downloaded old data instead of the curent change that i made.
If i delete the row, the rows gets delete at the suscriber, if a insert the row the row get insterted ok.
The problem only happen with rows inserted at the suscriber, that later on get update at the publisher. My suscriber has MSDE 2000 SP3 an my Server has SQL Enterprice 2000 SP4.
Hi all, One year ago, I did "Ruuning Setup to Install AdventureWorks Sample Databases and Sample" to install "AdventureWorks" in my SQL Server Management Studio Express. Now, It just have the name "AdventureWorks" on and no contents (no tables, schemas, etc.) in it. In my Control Panel, Add or Remove Programs, AdventureWorksDB (162.00 MB) is still there and AdventureWorks (Windows Installer Package [27,992 KB]) is in my C:/drive.
(1) Should I delete the name "AdventureWorks" in my SQL Server Management Studio Express, and remove AdventureWorksDB (162.00 MB) from the Add or Remove Program, before I re-install AdventureWorks, AdventureWorksDW, and Adventure Works DW sample databases and samples from Windows Installer Package [27,992 KB]? Is my old AdventureWorks (Windows Installer Package [27,992 KB]) still good and complete for installation? (2) SQL Server 2005 Books Online (September 2007) presents "Reinstalling Sample Databases from Script". But (i) I can not find the file instawdb.sql for reinstalling AdventureWorks from script and I do not have AdventureWorks OLTP in my C:Program FilesMicrosoft SQL Server90ToolsSamples folder, (ii) I can not find the file instawdwdb.sql for reinstalling AdventureWorksDW from script and I do not have AdventureWorks Data Warehouse in my C:Program FilesMicrosoft SQL Server90ToolsSamples folder either!!?? Please help and tell me what is the best way and some detailed instructions/tips to have AdvenureWorks, AdventureWorksDW, and Adventure Works DW sample databases and samples installed in my SQL Server Management Studio Express.
I am looking for some material for downloading documents from sql server. I can upload documents in my app but i would also like to download those files too.
I keep getting eeror mess when downloading SQL server 2005. Micro soft cust service says they are not qualified to fix but if I pay $99.00 they can have someone help with it.
I think that is nuts since they are sending me the download. I tried to do it manually and some components installed but everyday I get update notifications
I'm trying to import data from an Informix Database to my SQL Server 2005 database with the import/export wizard. I have an ODBC-connection that works, Access fetches data with no errors. From the wizard I can only choose to use the IBM Informix OLE DB Provider as datasource. As fare as I know the OLE DB Provider is using settings from the ODBC-driver?
In SQL Server 2000 there is a posibillity to choose Other(ODBC provider) as datasource which works against this database. Any ideas how i can use an ODBC-datasource?
If I try to use the IBM Informix OLE DB Provider I get an error message after the first step of the wizard:
Cannot get the supported data types from the database connection "Provider=Ifxoledbc;Password=;Persist Security Info=True;User ID=uid;Data Source=db@server".
I am trying to download the SQL Express Server 2005 software direct from Microsoft. I am having trouble locating the ENGLISH version. I am located in Frane but prefer using software in my native language....no pun intended. Every attempt to d/l gives me the French version. Can anyone provide me a link for the ENU version of SQL Express Server 2005.
I have a problem downloading Microsoft SQL Server 2005 Express Edition with Advanced Services.
Every time I download the complete file (234 mb) I get an error that the downloaded file is corrupt. I've tried also downloading it on other locations but every time the file is corrupt.
Is there another way to obtain this version of SQL server 2005 ?
I had a small requirement i had a table with embedded attachments and attachments are uploaded to the table and saved in varbinary field from front end. Want i want is i want to download particular embedded files in that table within SQL Server itself. I have tried googling but none of seems to be within SQl Server T-SQL. all are linked to Asp.NET how i can do?
If I try to download using a download manager it stops after 98% (the segment that stops is the first segment). If I try to download without a download manager it stops after 1% (456Kb).
What can I do?
Is there an alternate place where I can download the file?
Hi , I am an Informix user who has shifted to SQL Server,,,,I just wanted to know the equivalent of 'ISOLATION TO DIRTY READ' as in Informix in SQL SERVER....
Anyone here ever used the Informix database and can give me some differences between Informix and SQL.
One of our users is thinking about purchasing a COTS product that only supports an Informix database. I need to convince the user to evaluate other rival applications that can support SQL and need some arguments in favor of not going with Informix.
I am considdering to link a Informix database (running on SCO Unix) to a SQL Server 2005. Only problem is ... I have no idea how to do this! The reason I'm attempring this is to try and see if it would fix a problem I'm experiencing when using Reporting Services to generate reports from a Informix data source. I've been told that setting up a linked server might fix the problem. If anyone could perhabs guide me through setting up the linked server I would be very grateful! The ODBC credentials for setting up a connection to the Informix DB as follows:
we r doing some application and SQL server as backend DB Server. this sql server has to be updated continiously 24*7 with data from 3 external sources Cache DB, Iformix and Oracle DB servers. How to handle this in such away that all changes at 3 external sources to be updated to SQL server and this data will use by our application at frondend. we though of ODBC., but ODBC is very very slow. It should lke Shadowing. How to handle this?. any help will greatly appreciated.
Does anyone know where to get a migration tool for porting Informix stored procedures to SQL Server? I'm not looking forward to hand migrating 111 stored procedures. I can't find a migration tool on the net. :eek:

What can be the reason(s) why I can't get data from a linked server using an ODBC datasource that works fast & fine from MS Access?
I have an ODBC connection (System DSN) configured for an Informix ODBC driver. The Test button (belonging to this driver-setup) reports a successfull connection test. Getting data from this database by linking tables in MS Access works fast and easy. But I have tried for many days now to setup a linked server from SQL Server (2005) Creation goes fine, but as soon as I issue a query, (e.g. 'select * from infrem723...remotetable' or using 'openquery') I get the following error: ---
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDASQL" for linked server "infrem723" reported an error. The provider did not give any information about the error.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "infrem723".

Why is Access able to read what "MSDASQL" cannot? I am desperate - can anybody help?Thanks a lot!
Hi, I'm trying to set up a linked server in sql server 2000 (in both win2k an NT) with informix. I've tried using the informix cli driver to ODBC and the OLE DB driver provided by IBM, but I always get errors.
When I try to set the linked server with ODBC the error is : 7399 , It says that the provider did not give any information about the error (..??...) I tested the DSN with the dbping tool and it works fine. I also testet it linking tables with access and also works.
When I try to set up the server using OLE DB, the erro message is Error: 7303 Could not initialize data source object of OLE DB provider "ifxoledbc".OLEDB erro trace [OLE/DB Provider 'Ifxoledbc' IDBInitialize::Initialize returned 0x80040e21: [PROPID=unknown PROPERTY ID VALUE = " .... and so on.....
In both machines, sql server have sp3, the latest MDAC.
The curious thing is that in another machine running windows NT (it's almost a twin of the trouble machine) the linked server works fine and I even can run querys.
I'm desperate!! could anybody help me please!!!!!!!!!!
PD: Attached is an image that shows the error message
I am trying to use Integration Services for something I've never done before; i.e., download a few files from an AS 400 and then turn around an email them to a user.
My basic problem is that I don't know where to start to get the files from the AS400 to a directory on the SQL Server. I have an Iseries ODBC connection configured correctly that will let me get to the files. Do I use a file system task to get the files from the AS 400 or do I use a data flow task? Don't know what task to start with. Once I get the files into a directory on the SQL server I don't think I will have any trouble emailing them.
I know it's a silly question but I've looked at a couple of books without any obvious answer popping out.
