ContentДЇirstly, download and install the latest Informix drivers for Windows: This article reveals how toВ make Microsoft SQL Linked Server and Informix Standard Engine work together. However, the settings are not obvious that are required to make this work with Informix Standard Engine (SE) вЂ“ the legacy version of Informix that uses C-ISAM to store tables (*.dat) and indexes (*.idx) in individual files (whereas Dynamic Server manages storage within its own вЂњdbspacesвЂќ). If you need to add additional linked servers for other instances, that can be done following exactly the same format described above without additional DSN entries.Microsoft SQL Server is a popular choice for consolidation of report data from multiple database products, as its Linked Server feature вЂ“ which is included in the base product вЂ“ makes it possible to access tables in heterogeneous databases within T-SQL via OLE DB or ODBC. + N'DB_LOCALE=en_US.819 CLIENT_LOCALE=en_US.819 ' -Change to your locale, as neededД®XEC = N'UCCX', -Linked Server system ', -Your System DSN you're dealing with a single instance, it should be enough to simply match the values used to create your System DSN. + N'SERVICE= ' -Informix service name, ex. + N'HOST= ' -Informix Hostname or IP adddress Modify as needed: DECLARE NVARCHAR(4000) The provider string is pulled into a variable for inline commenting purposes only, while still having executable code.

If you're more of a manual SQL kind of person, see below. Provider: Microsoft OLE DB Provider for ODBC Drivers.The trick with the Linked Server setup is to use the following (items in codeblocks are literal): Additionally, set up a corresponding System DSN entry. Use the SetNet32 application provided with the drivers and set up the Server Information tab appropriately.

The correct IBM Informix ODBC Driver must be installed on the database server.

Ultimately, the solution had several parts, of which you've done the first few: I would consistently receive the same errors as you, and nothing I was able to dredge up online proved helpful. I had several Informix instances that needed to be linked to a single SQL Server instance for warehousing purposes, and was told by our resident SME that this was impossible only a single Informix instance could be referenced per server. We had a nightmare setting something similar up, specifically with the issue of connecting to multiple Informix environments. I have very little experience with Informix which should be apparent and this isn't a local installation, it's a Cisco instance as you probably gleaned from the blogs I was using.

SQLNCLI11 for linked server UCCX returned message 'Invalid connection string attribute' Check if instance name is correct and if SQL Server is configured to allow remote connections. OLE DB provider SQLNCLI11 for linked server UCCX retunred a message 'A network-related or instance-specific error has occured while establishing a connection to SQL Server. OLE DB provider SQLNCLI11 for linked server UCCX returned message 'Login timeout expired' Named Pipes Provider: Coould not open a connection to SQL Server. OLE DB provider 'Ifxoledbc' for linked server 'UCCX' returned messazge 'EIX000: (-23197)' Database locale information mismatch' (Microsoft SQL Server, Error: 7303)Дў) Using Microsoft OLE DB Provider for SQL Server as explained in this blog which returns the error: Googled and read everything I could to resolve this without success.ДЎ) Using IBM Informix instructions with OLE DB Provider in which I get the following error (regardless if I use a DNS in provider string):Д¬annot initialize the data source object of OLE DB provider 'Ifxoledbc' for linked server 'UCCX'.

Attempted to create the linked server in two ways below.

Tested the connectivity of the DSN settings (test is good) after changing the locale settings so the client and server match, and server is correct.

Configured a System DSN for the IBM Informix ODBC Driver Setup.

Installed the latest Informix OLE DB Driver on the SQL Server host machine.

I haven't tried this with other versions (2008R2, etc) since I wanted to set up the connection in a test environment first.

After about 3 days of trying, I am unable to create a linked server from SQL Server 2016 to Informix 11.5.
