Supported operating systems
If your database management system is installed where ArcGIS products are installed, the operating system must meet the ArcGIS product system requirements as well as the operating system requirements for your Oracle version.
If your database is not installed on the same server as an ArcGIS product, see the Oracle documentation for operating system requirements for your Oracle version.
Additional requirements for the ST_Geometry shape library
Esri supports the following four operating systems when you use the ST_Geometry shape library and configure Oracle external procedure (extproc). Minimum operating system versions are listed if the minimum version that Esri supports differs from what Oracle databases support.
- IBM AIX (64 bit)—For Oracle 126.96.36.199, the minimum supported version is IBM AIX 188.8.131.52.
- Linux (64 bit)—For Oracle 184.108.40.206, the minimum supported version is Red Hat Enterprise Linux (RHEL) Server AS/ES 5 - update 11.
- Solaris (64 bit)—For Oracle 220.127.116.11, the minimum supported version is Solaris 10 SPARC.
- Microsoft Windows (64 bit)
On Windows, you need the latest Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, and 2019 installed on the Oracle database machine. See the latest supported Visual C++ downloads from Microsoft support for more information.
Branch versioning is supported at Oracle 18.104.22.168 and later releases.
The Oracle Text component must be installed. The Text component is installed by default in Oracle; however, if you did not perform a default installation, the Text component may not have been installed.
Oracle database patch support
See Oracle Support for all Oracle patch set (and Interim Patch) documentation and installation instructions. Esri recommends making a full backup of your Oracle database prior to applying any Oracle patch sets or interim patches. If functionality that was working prior to applying the Oracle patch set or interim patch stops working, return to the previous version of Oracle. Contact Oracle support as needed.
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.
