1.3 Oracle Machine Learning for R Installation Steps
These steps and this roadmap illustrate a typical OML4R installation.
For Oracle Database 19c or later, use the rqcfg.sql script to install OML4R Server, as described in Install Oracle Machine Learning for R Server for Oracle Database 19c or later.
Note:
If you intend to use both client and server components of OML4R on the computer that is hosting Oracle Database, then you do not need to perform a separate client installation. A local installation of Oracle Database Client is automatically included in the installation of Oracle Database.

OML4R Installation Roadmap
This roadmap provides the steps required to install and configure a typical OML4R environment. To install OML4R, do the following:
-
Verify that your system meets the basic requirements
-
Obtain the correct installation software
-
Perform and validate the installations
Table 1-1 Tasks for Installing OML4R
| Task | Description | Documentation |
|---|---|---|
|
1. Review the OML4R sample installation. |
Review the steps for a typical installation of OML4R on a Linux server and a Windows client. Note: All the supported configurations are listed in Oracle Machine Learning for R System Requirements for On-Premises Database. |
|
|
2. Verify supported platforms and system requirements. |
Use the Platform Requirements table and Server Support Matrix to verify your environment meets the requirements for installation. |

|
3. Identify installation users for Oracle R Distribution and OML4R. |
The user executing the installation and configuration on your system requires sufficient permissions and privileges. For Oracle R Distribution, the installation user is root (Unix/Linux) or Administrator (Windows). |
User Requirements for OML4R Server |
|
4. Download the product installers. |
Oracle R Distribution is available from Oracle’s public yum or the Oracle download site. Oracle Database and Oracle Machine Learning for R are available on the Oracle download site. For Oracle Database 18c and later, the OML4R installers are shipped with Oracle Database. |

|
5. Install and configure Oracle Database. |
OML4R requires the 64-bit version of Oracle Database Enterprise Edition. |

|
6. Install and configure R. |
OML4R requires an installation of R on each node of the server and on each client computer that interacts with the server. Oracle R Distribution is recommended. The OML4R Server components must be installed on the database server. |
|
|
7. Install and configure OML4R Server. |
OML4R includes several components on the server. Together these components enable an OML4R client to interact with an OML4R server. |
|
|
8. Install Open Source R packages on the OML4R server. |
Embedded R execution with OML4R allows the use of CRAN or other third-party R packages in user-defined R functions executed on the Oracle Database server. |

|
9. Install and configure the OML4R client. |
If a physical client is configured, then you must install the following OML4R components separately on each client computer:
If you wish to run the OML4R client through a web browser, then install RStudio Server on the database server (Linux only). |
|
|
10. Install Open Source R packages on the OML4R client. |
R packages installed on the OML4R server must also be installed on the OML4R client. |
|
|
11. Verify the OML4R Installation. |
Test the OML4R installation by connecting to the OML4R client to the server and executing some OML4R functions. |
