- 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.

Software required to connect to a DBMS
Your client machine (for example, the one running ArcGIS Pro or ArcGIS Server) must have the appropriate client files installed for the RDBMS you're using. These client files are available from their respective RDBMS vendors, but some are also available from My Esri. RDBMS client files available from My Esri are IBM Db2 and Microsoft SQL Server. Client files for all other supported databases must be obtained from the RDBMS vendors. See Database clients for more information.
