This presentation shows how to install and configure Oracle R Enterprise Server 1.5 on Oracle 12C Linux OEL6.

Architecture

Following picture shows general architecture of Oracle R. This article will focus only on installation of Server parts.

Installation steps for Server parts

Installation consists of three steps:

• Install Oracle Database Enterprise Edition (not presented in this article just look for installation of 12C on OEL6 on my blog)
• Install Oracle R Distribution (presented in this article) or Open Source R
• Install Oracle R Enterprise Server

Software to install

Following table shows software certification matrix 64-bit Red Hat Enterprise Linux Release 5 update 6 through Red Hat Enterprise Linux 6

1.4.1	3.0.1, 3.1.1	11.2.0.3, 11.2.0.4, 12.1.0.1
1.4	3.0.1, 3.1.1	11.2.0.3, 11.2.0.4, 12.1.0.1
1.3.1	2.15.1, 2.15.2, 2.15.3	11.2.0.3, 11.2.0.4, 12.1.0.1
1.3	2.15.1	11.2.0.3, 11.2.0.4, 12.1.0.1
1.2	2.15.1	11.2.0.3, 11.2.0.4, 12.1.0.1
1.1	2.13.2	11.2.0.3, 11.2.0.4, 12.1.0.1
1.0	2.13.2	11.2.0.3, 11.2.0.4, 12.1.0.1

In this installation I use following software:

• Oracle R Enterprise 1.5 – later referenced as ORE 1.5

Packages to download ORE 1.5 are here:

http://www.oracle.com/technetwork/database/database-technologies/r/r-enterprise/downloads/index.html

You need to download “supporting” and “server” for Linux 64-bit.

ore-server-linux-x86-64-1.5.zip  
ore-supporting-linux-x86-64-1.5.zip

copy them to some directory of user oracle (/home/oracle/oinstall) and change owner and group(oracle:oinstall)

[root@oel6 ~]# cp ore* /home/oracle/install
[root@oel6 ~]# cd /home/oracle/install
[root@oel6 ~]# chown oracle:oinstall ore*

• Oracle R Distribution 3.2.x

To download it first ensure Oracle addons are available

cd /etc/yum.repos.d/

vi public-yum-ol6.repo

[public_ol6_latest]
name=Oracle Linux $releasever Latest ($basearch)
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1

[public_ol6_addons]
name=Oracle Linux $releasever Add ons ($basearch)
baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/addons/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1

Install Oracle R Distribution

Install as user root

yum install R-3.2.0

Install Oracle R Enterprise Server

As user Oracle unizp software. Make sure owner of the files is oracle

cd /home/oracle/install
[oracle@oel6 install]$ chown oracle:oinstall ore*

[oracle@oel6 install]$
unzip ore-server-linux-x86-64-1.5.zip  
unzip ore-supporting-linux-x86-64-1.5.zip

Start installation

As user Oracle

set ORACLE_SID before installation for your database. NOTE Installation of ORE is executed on pluggable database. It’s supported solution.

EXPORT ORACLE_SID=ORA12C

Then run server.sh script. This script works as well as upgrade script.

You will be asked to provide (I just put examples):

• pluggable databasse name for container type architecture
• permanent tablespace for user RQSYS – USERS
• temporary tablespace for user RQSYS – TEMP
• password for user RQSYS – oracle12c
• choosing ORE user name – ORE
• permanent tablespace for user ORE – USERS
• temporary tablespace for user ORE – TEMP
• password for user RQSYS – oracle12c

Installation verification

As user Oracle connect to database using $ORACLE_HOME/bin/ORE. You should see prompt “>”

$ORACLE_HOME/bin/ORE
>

once you connected via ORE load oracle library. It’s required for next steps

library(ORE)

establish connection to pluggable database

ore.connect(user="ORE", service="PORA12C1.dbaora.com", host="oel6.dbaora.com",password="oracle12c", port=1521, all=TRUE)

if you use not pluggable database then try following

ore.connect(user="ORE", sid="ORA12C", host="oel6.dbaora.com",password="oracle12c", port=1521, all=TRUE)

List of tables should be empty.

## Is the ORE client connected to the ORE server?
## The output of this command should be TRUE.
ore.is.connected()

## List the available database tables 
ore.ls()

list demos available for test

demo(package="ORE")

Run some sample demos

demo("aggregate", package="ORE")
demo("row_apply", package="ORE")

Have a fun 🙂
