Supported operating systems

If your database management system is installed on a server where ArcGIS products are installed, the server operating system must meet the ArcGIS product system requirements as well as the operating system requirements for your Informix version.
If your database is not installed on the same server as an ArcGIS product, see the IBM documentation for operating system requirements for your Informix version.

Software required to connect to a DBMS

Your client machine (for example, the one running ArcMap) will need to have the appropriate client files installed for the RDBMS you are using. These client files are available from their respective RDBMS vendors, but some are also available on My Esri as a convenience. RDBMS client files available from My Esri are IBM DB2 and Microsoft SQL Server. Client files for ALTIBASE, Dameng, IBM Informix, IBM Netezza, Oracle, SAP HANA, and Teradata are not available on My Esri and must be obtained from the RDBMS vendors. See Database clients for more information.
