A.2.2 Install Oracle R Distribution

To install Oracle R Distribution on the server from Oracle public yum, follow these steps:

Log in as root and change to /etc/yum.repos.d:
```
cd /etc/yum.repos.d
```
List the contents of the directory to determine if the yum configuration file is present. The yum configuration file for Oracle Linux 6 is called public-yum-el6.repo.
If public-yum-el6.repo is not present, then execute the following command to download it from Oracle public yum:
```
wget http://public-yum.oracle.com/public-yum-el6.repo
```
Open public-yum-el6.repo in a text editor and specify enabled=1 for latest and addons:
```
[el6_latest]
enabled=1

[el6_addons]
enabled=1
```
Install Oracle R Distribution 3.3 by executing these commands:
```
yum install R-3.3.0
yum install R-core-extra
```
Set LD_LIBRARY_PATH to the location of the files installed by the R-core-extra RPM:
Exit the root user.
```
exit
```

A.2.3 Install Oracle R Enterprise Server

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

To install Oracle R Enterprise Server:

Verify the environment according to Table A-1.
Create an installation directory for the Oracle R Enterprise server components. The directory can have any name. For example:
```
/myhome/myoreserver/
```
Download the Oracle R Enterprise Server installation files and supporting packages from the Oracle R Enterprise Downloads page on the Oracle Technology Network.
1. Accept the license agreement and download the Oracle R Enterprise Server files for your platform to your installation directory.
2. Accept the license agreement and download the Oracle R Enterprise 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/myoreserver
     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 Oracle R Enterprise 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.
