1 Overview of Oracle R Enterprise Installation

This chapter introduces the Oracle R Enterprise installation process. This chapter contains the following topics:

1.1 About Oracle R Enterprise

Oracle R Enterprise integrates R, the open source scripting language and environment, with Oracle Database. R supports advanced statistical analysis and has sophisticated graphical capabilities. Oracle R Enterprise provides powerful and scalable in-database algorithms for model building and data scoring. A component of the Oracle Advanced Analytics Option of Oracle Database, Oracle R Enterprise enables the R language to operate transparently on Oracle data and to execute user-defined R scripts through Oracle Database on the database server machine.

1.2 About Oracle R Enterprise and Open Source R

Oracle R Enterprise requires the installation of R, which is third-party, open source software. Open source R is governed by GNU General Public License (GPL) and not by Oracle licensing. The following Oracle tools facilitate and enable the use of R with Oracle Database:

  • Oracle R Distribution

    Oracle R Distribution is Oracle's free distribution of open source R. Oracle R Distribution offers these significant advantages for Oracle R Enterprise:

    • Simplifies the installation of R for Oracle R Enterprise

    • Simplifies integration with the Intel Math Kernel Library (MKL) on Linux and Windows platforms. MKL greatly improves the performance of many mathematical computations in R, including highly vectorized and threaded Linear Algebra, Fast Fourier Transforms (FFT), Vector Math, and Statistics functions.

    • Automatically uses Sun Performance Library on Oracle Solaris systems. Like MKL for Linux and Windows, Sun Performance Library offers improved performance of many mathematical computations on Oracle Solaris. Sun Performance Library is part of Oracle Solaris Studio.

    • Oracle provides support for Oracle R Distribution to customers of Oracle Advanced Analytics, Oracle Enterprise Linux, and Oracle Big Data Appliance.


    Oracle recommends that you use Oracle R Distribution with Oracle R Enterprise whenever possible.

    If you choose to use open source R with Oracle R Enterprise, then you must build it from source. See Section 3.1.2 for instructions.

  • ROracle

    ROracle is an open source R package that enables interaction between R and Oracle Database. Originally developed by a third party, ROracle has been enhanced by Oracle and is now maintained and supported by Oracle. ROracle is one of the supporting packages used by Oracle R Enterprise.

1.3 About Oracle R Enterprise and Oracle R Advanced Analytics for Hadoop

Oracle R Advanced Analytics for Hadoop provides a general computation framework in which you can create R scripts and execute them on an Hadoop cluster. Oracle R Advanced Analytics for Hadoop includes a collection of R packages that provides interfaces to work with Apache Hive tables, the Apache Hadoop compute infrastructure, the local R environment, and Oracle database tables.

Oracle R Advanced Analytics for Hadoop provides a basic level of access to Oracle Database. You can move the contents of a database table to HDFS, and move the results of HDFS analytics back to the database. You can then perform additional analysis on the reduced data set using Oracle R Enterprise.

1.4 Oracle R Enterprise Architecture

Oracle R Enterprise has a client-server architecture based on Oracle Database and Oracle Client. R engines run on the server computer and on each client computer.

  • SQL Transparency

    Oracle R Enterprise packages on the client support SQL transparency, which enables Oracle tables to appear "transparently" as native R objects. With SQL transparency, data analysts can use R to explore, cleanse, and transform data without having to know SQL.

  • Embedded R Execution

    Oracle R Enterprise packages, libraries, and R and SQL APIs on the server support the execution of R commands within SQL queries and PL/SQL statements. Embedded R is executed in spawned R engines that can run in parallel. With embedded R, you can execute R algorithms on very large data stores, and you can use database facilities like DBMS_SCHEDULER to schedule the execution of user-defined R functions for lights out processing.

Figure 1-1 illustrates the client-server architecture of Oracle R Enterprise.

Figure 1-1 Client-Server Architecture of Oracle R Enterprise

Description of Figure 1-1 follows
Description of "Figure 1-1 Client-Server Architecture of Oracle R Enterprise"

1.5 Client and Server Components of Oracle R Enterprise

Oracle R Enterprise has client components and server components:

  • Oracle R Enterprise Client Components:

    • Oracle Database Client

    • Oracle R Enterprise packages and supporting, open source packages

  • Oracle R Enterprise Server Components:

    • Oracle Database with schema objects and shared libraries for supporting Oracle R Enterprise clients

    • Oracle R Enterprise packages and supporting, open source packages

1.6 Oracle R Enterprise Installation Steps

The Oracle R Enterprise client and server installation steps are illustrated in Figure 1-2.

Figure 1-2 Oracle R Enterprise Client and Server Installation Steps

Description of Figure 1-2 follows
Description of "Figure 1-2 Oracle R Enterprise Client and Server Installation Steps"


If you intend to use both client and server components of Oracle R Enterprise on the computer that is hosting Oracle Database, then you do not need to perform a separate client installation. A local installation of Oracle Database Client is automatically included in the installation of Oracle Database.

1.6.1 Postinstallation Steps

After you install the software, you must create at least one database user for Oracle R Enterprise. A script for creating users is provided with Oracle R Enterprise Server.

1.7 Oracle R Enterprise System Requirements

Oracle R Enterprise runs on 64-bit platforms only. Both client and server components are supported on each of the platforms described in Table 1-1.
