Oracle R Enterprise Configuration on Oracle Linux


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:
    install.packages("DBI")
    install.packages("png")
    
  • Ensure that your database is 11.2.0.3 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
  • Execute install.sh in order to create ORE libraries and database objects into SYS and RQSYS schemas.
    cd server
    ./install.sh

    Checking R ................... Pass
    Checking R libraries ......... Pass
    Checking ORACLE_HOME ......... Pass
    Checking ORACLE_SID .......... Pass
    Checking sqlplus ............. Pass
    Checking ORE ................. Pass

    Choosing RQSYS tablespaces
    PERMANENT tablespace to use for RQSYS [SYSAUX]:
    TEMPORARY tablespace to use for RQSYS [TEMP]:

    Current configuration
    R_HOME = /usr/lib64/R
    R_LIBS_USER = /u01/app/oracle/product/11.2.0/dbhome_1/R/library
    ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1
    ORACLE_SID = orcl
    PERMANENT tablespace = SYSAUX
    TEMPORARY tablespace = TEMP

    Installing libraries ......... Pass
    Installing RQSYS ............. Pass
    Installing ORE packages ...... Pass
    Creating ORE script .......... Pass

    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
    roles.

    Done

  • Finally install some required R libraries/packages by using install.packages command in R. Ensure that user (root will do that) you will start R has a write permission on /usr/lib64/R/library
    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/lib is in your LD_LIBRARY_PATH before starting R session) and load ORE library
    library(ORE)
    Loading required package: OREbase
    Loading required package: ROracle
    Loading required package: DBI
    
    Attaching package: 'OREbase'
    
    The following object(s) are masked from 'package:base':
    
        cbind, data.frame, eval, interaction, order, paste, pmax, pmin,
        rbind, table
    
    Loading required package: OREstats
    Loading required package: MASS
    Loading required package: OREgraphics
    Loading required package: OREeda
    Loading required package: ORExml
