With exadata x3 models, oracle delivers oracle r enterprise at the compute node operating
system level as well as oracle r functions and packages inside the database. the following examples will
show you how to install r in an exadata x2-2 environment. By default, r is not installed on the exadata Compute
nodes or storage cells and although oracle discourages installing additional software on the compute nodes,
http://docs.oracle.com/cd/E11882_01/doc.112/e26499/install.htm#BABCEACI
provides instructions specific
for exadata. if your organization does not allow you to install r on a compute node, an alternative approach is to extract
cellcli
data to a different server or workstation and analyze the results from there.
Prior to executing the scripts provided in this recipe, you will need to install R on an Exadata Compute Node. To
accomplish this, first download the
public-yum-el5.repo
file from
http://public-yum.oracle.com/public-yum-el5.
repo
and place it under
/etc/yum.repos.d
. Disable the current Exadata repository by renaming the existing repository
with the
.disabled
suffix:
[root@cm01dbm01 yum.repos.d]# ls -l
total 12
-rw-r----- 1 root root 220 Oct 11 03:17 Exadata-computenode.repo.disabled
-r--r----- 1 root root 1160 Jul 13 13:39 Exadata-computenode.repo.sample
-rw-r--r-- 1 root root 3974 Oct 30 02:20 public-yum-el5.repo
[root@cm01dbm01 yum.repos.d]#
Next, set
enabled=1
for the el5_addons and el5_oracle_addons stanzas in the
pubic-yum-el5.repo
file:
[el5_addons]
name=Enterprise Linux $releasever Add ons ($basearch)
gpgcheck=1
enabled=1
When this is complete, run
yum install R
as
root
on your compute node:
[root@cm01dbm01 yum.repos.d]# yum install R
el5_addons | 1.2 kB 00:00
el5_latest | 1.4 kB 00:00
el5_oracle_addons | 951 B 00:00

After R is installed, you can validate it by launching
R
:
[root@cm01dbm01 yum.repos.d]# R
