1.4 Oracle Machine Learning for R System Requirements

OML4R runs on 64-bit platforms only.

Both client and server components are supported on each of the platforms described in this topic.

Table 1-2 Oracle Machine Learning for R Platform Requirements

Operating System	Hardware Platform	Description
Linux x86-64	Intel and AMD	64-bit Oracle Linux Releases 6, 7, and 8 64-bit Red Hat Enterprise Linux Releases 6 and 7 Note: Starting with R-3.6.1, Linux 6 is no longer supported. Oracle Linux may be running on Oracle Exadata Database Machine.
Oracle Solaris on x86-64 (64-Bit) Oracle Solaris on SPARC-64 (64-Bit)	Intel and SPARC	64-bit Oracle Solaris 10 update 11 through Oracle Solaris 11 for both SPARC and x86-64 (Intel) platforms Oracle SPARC SuperCluster Oracle Solaris Studio (formerly Sun Studio) 12u3 or later Oracle Solaris may be running on Oracle Exadata Database Machine.
IBM AIX on POWER Systems (64-Bit)	IBM	64-bit IBM AIX 5.3 or higher
Microsoft Windows x64 (64-Bit)	Intel	64-bit Microsoft Windows Professional

The following table shows the supported configurations of OML4R Server components. Oracle recommends that you use Oracle R Distribution, Oracle's free distribution of R, with OML4R. You should install Oracle R Distribution before installing OML4R.

1.0	2.13.2	11.2.0.3, 11.2.0.4, 12.1.0.1

Note:

The version of R must be the same on the server and on each client computer. Also, the version of OML4R must be the same on the server and on each client computer.

Note:

R-3.6.1 has an OML4R 1.5.1 binary built under R-3.6.1 and is not compatible with the OML4R 1.5.1 built under R-3.3.0.

Note:

Starting with Oracle Database 18c, to install OML4R you must use the installation scripts that come with the database. See Install Oracle Machine Learning for R Server for Oracle Database 18c and Later.

Note:

In Oracle Database Release 12.1.0.2, for some embedded R operations to be successful, Oracle R Enterprise releases 1.4.1 and later require the database patch -- 20173897 WRONG RESULT OF GROUP BY FROM A TABLE RETURNED BY EXTPROC (Patch).

Verifying 64-Bit Architecture on Microsoft Windows

OML4R only runs on 64-bit operating systems. You can determine if your Windows system is 64-bit by following these steps:

• Windows 7 or Windows Vista:

  1. From Windows Control Panel, choose System.

  2. Verify that System type is 64-bit Operating System.

• Windows XP:

  1. From the Start menu, choose My Computer.

  2. Click Properties.

  3. On the System tab, verify that the system is x64 Edition.
