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 ArcGIS Pro, ArcMap, or ArcGIS Server) must have the appropriate database client files installed for the RDBMS you are using. These client files are available from their respective RDBMS vendors. See Database clients for more information.
