A.2.3 Install Oracle Machine Learning for R Server

OML4R Server includes the RQSYS schema in Oracle Database and OML4R packages and shared libraries.

To install OML4R Server:

Verify the environment according to Table A-1.
Create an installation directory for the OML4R Server components. The directory can have any name. For example:
```
/myhome/myomlserver/
```
Download the OML4R Server installation files and supporting packages from the Oracle Machine Learning for R Downloads website.
1. Accept the license agreement and download the OML4R Server files for your platform to your installation directory.
2. Accept the license agreement and download the OML4R Supporting packages for your platform to your installation directory.
The installation directory now contains two zip files.
```
ore-server-linux-x86-64-1.5.1.zip
ore-supporting-linux-x86-64-1.5.1.zip
```

Unzip the files.

unzip ore-server-linux-x86-64-1.5.1.zip
unzip ore-supporting-linux-x86-64-1.5.1.zip

The installation directory looks like this after you unzip both files:

/myhome/myomlserver
     ore-server-linux-x86-64-1.5.1.zip
     ore-supporting-linux-x86-64-1.5.1.zip
     server.sh
     /server
     /supporting

Run server.sh to perform a default installation of OML4R Server as shown in the following example. In this example, the script runs interactively. User input is shown in bold.

Note:

When the script displays [list] in a prompt, you can press Enter to obtain a list of available items for your choice.
On Oracle Linux 6, set LD_LIBRARY_PATH to the location of the files installed by the R-core-extra RPM:
```
export LD_LIBRARY_PATH=/usr/lib64/R/port/Linux-X64/lib
```

Example A-1 A Default, First-Time Installation of OML4R Server
