Before starting to deal with large volumes of data problems on Oracle R Enterprise (ORE) you need to perform a couple of configurations over your Oracle Linux and Oracle Database systems. Here is the recipe:
- Ensure that you have the following lines in your oracle users .bash_profile file
export R_HOME=/usr/lib64/R export PATH=/usr/bin:$PATH
- Ensure that you have already installed libpng.x86_64 and libpng-devel.x86_64 packages on your Oracle Linux otherwise issue to install them.
yum install libpng.x86_64 libpng-devel.x86_64
- Switch to root and issue R. Once you are in R session, install two prerequisites of ORE:
- Ensure that your database is 184.108.40.206 otherwise refer you need to apply several database patches:
- Go to Oracle R Enterprise Download Page and download Oracle R Enterprise Server Install for Oracle Database on Linux 64-bit (91M) and Oracle R Enterprise Client Supporting Packages for Linux 64-bit Platform (1M) (ore-server-linux-x86-64-1.1.zip and ore-supporting-linux-x86-64-1.1.zip) under Oracle R Enterprise Downloads (v1.1) section
- Unzip the file by issuing
unzip ore-server-linux-x86-64-1.1.zip ore-supporting-linux-x86-64-1.1.zip
- At this point ensure that your database to support Oracle R Enterprise is up and running
install.shin order to create ORE libraries and database objects into SYS and RQSYS schemas.

NOTE: To use ORE functionality, a database user with RQROLE role,
a few more grants and synonyms is required. A complete list of
requirements is available in rquser.sql. There is also a demo
script demo_user.sh creating a new user RQUSER.
To use embedded R functionality, an RQADMIN role is required.
Please, consult the documentation for more information on various
- Finally install some required R libraries/packages by using
install.packagescommand in R. Ensure that user (
rootwill do that) you will start R has a write permission on
install.packages("/home/oracle/Desktop/server/ORE_1.1_R_x86_64-unknown-linux-gnu.tar.gz", repos = NULL) install.packages("/home/oracle/Desktop/server/OREbase_1.1_R_x86_64-unknown-linux-gnu.tar.gz", repos = NULL) install.packages("/home/oracle/Desktop/server/OREeda_1.1_R_x86_64-unknown-linux-gnu.tar.gz", repos = NULL) install.packages("/home/oracle/Desktop/server/OREgraphics_1.1_R_x86_64-unknown-linux-gnu.tar.gz", repos = NULL) install.packages("/home/oracle/Desktop/server/OREstats_1.1_R_x86_64-unknown-linux-gnu.tar.gz", repos = NULL) install.packages("/home/oracle/Desktop/server/ORExml_1.1_R_x86_64-unknown-linux-gnu.tar.gz", repos = NULL) install.packages("/home/oracle/Desktop/supporting/ROracle_1.1-2_R_x86_64-unknown-linux-gnu.tar.gz", repos = NULL)
- Finally start a R session (ensure that
$ORACLE_HOME/libis in your
LD_LIBRARY_PATHbefore starting R session) and load ORE library
