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 11.2.0.4, the minimum supported version is IBM AIX 6.1.0.0.
  • Linux (64 bit)—For Oracle 11.2.0.4, the minimum supported version is Red Hat Enterprise Linux (RHEL) Server AS/ES 5 - update 11.
  • Solaris (64 bit)—For Oracle 11.2.0.4, 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.

  • Support for Oracle Linux is based on Oracle documentation that Oracle Linux is compatible—both source and binary—with Red Hat Enterprise Linux Server. See the Oracle Linux FAQ on the Oracle website.
  • Support for the Oracle Exadata Database Machine is based on Oracle guidance that OEM software that supports both Oracle Linux and Oracle RAC is compatible with Oracle Exadata.
  • A new option starting with Oracle 12c, called Multitenant Architecture, consisting of a container database that can hold many pluggable databases, is supported at the pluggable database level. ArcGIS supports the same functionality in pluggable databases as is supported for Oracle 11g R2.

Database requirements/limitations

Branch versioning is supported at Oracle 12.1.0.2 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.
