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:
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.
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?
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:

I am transferring the data from sql server 2005 to Informix 7.3.1 SE using SSIS .
I am using the OLEDB data connection for both source as well as destination databases.
I am trying to mapping the source and destination tables .I am getting the following error.
TITLE: Microsoft Visual Studio ------------------------------ Error at Data Flow Task [OLE DB Destination [184]]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E21. Error at Data Flow Task [OLE DB Destination [184]]: Opening a rowset for ""srinivas"."company"" failed. Check that the object exists in the database.

I am using the following ODBC driver for the connecting INFORMIX 7.3.1 which is running on LINUX environment. Openlink Generic ODBC Driver
It's creates the table in the informix 7.3.1 but it's not mapping the source and destination databases columns.

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!
I have created an Access2003 project (existing data) that links to external data. First I connected to a SQL Server 2000 database. Success. Then I tried to set up a Transact SQL data connection to a legacy MDW-secured Access97 database. (A third-party VB6 application goes against it, and we don't have the source code, so we cannot upgrade it.)
The Transact SQL link tests OK but I cannot select any of the tables or queries from the list presented. However, with the same credentials, I can use these same objects in Excel 2003.
When setting up the link in Access2003, I specify JET 4.0 OLE DB Provider, I enter the MDW file on the All tab, a username and a password on the Connection tab where I browse to the MDB file, and specify Shared Deny None on the Advanced tab. When I test the connection, it tests OK ("Test connection succeeded"). Yet on the "Select the Database and Table/Cube which contains the data you want" dialog, "(Default)" appears in the grayed-out dropdown. Then, beneath that dropdown, there is a grid with Name and Description columns. The grid contains query names but the grid is not enabled. The list of queries is this table is grayed out. Neither of the scrollbars works.
BUT... if I use the SAME username and password in Excel2003, and specify the same MDW, there is no problem working with these same database objects in the legacy Access97 database. WHAT IS DIFFERENT ABOUT THE WIZARD IN EXCEL THAT ALLOWS IT TO SUCCEED AND THE WIZARD IN ACCESS THAT CAUSES IT TO FAIL HERE? In Excel, the list of available providers says Microsoft Access Driver, not JET 4.0 OLE DB Provider.
When trying to link to an SQL table in Access 2003, the software appears to be malfunctioning.
The sequence of events is File - Get External Data - Link Tables - Files of Type: ODBC Databases().
The Problem: On two of my computers, the select data source window does not pop up, preventing me from linking to any ODBC data source.
Observations: This function has worked normally in the recent past and works on other computers running Access 2003. One difference between the computers working and non-working computers is Norton Antivirus 2006 (recent upgrade).
Has anyone experienced anything like this? What's going on?
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, 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 drag data from Informix to Sql Server. When I kick off the package using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP errors on two fields from Informix which are date data ....no timestamp part
I tried a couple of things:
Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.
Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them as datetime but it failed.
Can any one tell me what I did wrong? Tried to set up link server from SQL 7.0 to Oracle.I did it as it was instruct in BOL. When I tried to click on the table, I got this message "error 7399: OLE DB provider "MSDAORA" reported error. Thanks.
I have created a linked server using an userid that have access to 2 different databases. The linked was created successfully but I am only able to see tables in 1 database but not both. The tables of the databases that I can access is the default database of that userid. Is there a way to see all the tables from more than 1 database that the user is authorized to? Thanks.

Hi, I have two database one on local system and another on web both are in MS SQL 2005 Now I want to link both of them by using Link server but the System procedure ask of oledb I am not understanding what to do. I searched the web but ..... So plz tell me some link or code ........
Is it possible to link MSDE to another server through ODBC? I want to do this like you can in Access, where you get external data by linking tables. Any ideas? Thanks!
I am having two databases(MS-Sql) on two different servers.Let say they are Server1 and Server2.I am having some stored procedures(sps) which are executing on Server1.Results given by these sps are 6 different tables(Theses tables are temporary tables e.g #Table1 and they are created in one of the sps on Server1). And I want to use these 6 tables on Server2. But constraint here is, i can create link server for Server1 from Server2 but not from Server1 to Server2.So i can not access Server2 directly from Server1. Even if i am using custom tables here instead of temp tables(#) it will take me to solution but that is again a constraint i can not do this. Is there any alternative solution for Link server in this case? I dont want to go for OPENROWSET and OPENDATASOURCE b'coz of performance issue.
