This preface describes changes in Oracle R Enterprise Installation and Administration Guide for Oracle R Enterprise Release 1.5.1 and for earlier releases to Oracle R Enterprise Release 1.4.
This guide contains information about these installation changes for Oracle R Enterprise Release 1.5.1.
For information about other new features in Oracle R Enterprise Release 1.5.1, see Oracle R Enterprise User’s Guide.
New Data Manipulation Package
The new package OREdplyr contains Oracle R Enterprise functions for data manipulation such as filtering for rows, selecting specific columns, re-ordering rows, adding new columns, and summarizing data.
New Graph Analysis Package
Beginning with Oracle Database 12c, Release 2 (12.2) , the OAAgraph package provides an R interface to the Oracle Spatial and Graph Parallel Graph Engine (PGX) for use with Oracle R Enterprise and database tables. The OAAgraph package and its supporting packages require separate downloads and installation on server and client systems.

Oracle R Enterprise 1.5.1 requires R 3.3.0. As with earlier releases of Oracle R Enterprise, Oracle recommends that you use Oracle R Distribution.
Oracle R Distribution Installation
Beginning with Oracle R Distribution 3.3.0, you can install the Linux RPMs in a directory other than the default Linux R_HOME.
New RPM for Oracle R Distribution
This release has a new RPM R-core-extra-3.3.0-1.el6.x86_64.rpm.
R has always depended on several third party libraries, specifically, zlib, bzip2, xz, pcre, and curl. Prior to R-3.3.0, R depended on much older versions of these libraries, but, if they were not found on the system, bundled copies were included that were built on the fly.
R-3.3.0 depends on much newer versions of these libraries and no longer contains the bundled copies. This means that R 3.3.0 won't build against Linux 6 as is, because the native versions of these libraries are older than those that R-3.3.0 requires.
The R-core-extra RPM contains the required versions of these libraries and is provided as a convenience for users of Oracle Linux 6. Adding the location of the libraries in R-core-extra to LD_LIBRARY_PATH removes the need to built these libraries separately. Oracle Linux 7 introduces the required versions of these libraries, but the R-core-extra RPM is provided as a convenience if needed.

R 3.2 requirement
Oracle R Enterprise 1.5 requires R-3.2.0. As with earlier releases of Oracle R Enterprise, Oracle recommends that you use Oracle R Distribution.

Installing Oracle R Enterprise Client for details about the supporting packages
Installation and administration of Oracle R Enterprise Server are significantly enhanced.
A single script, server.sh or server.bat, performs all administrative operations that affect Oracle R Enterprise Server. You can run the script to install, upgrade, or uninstall the server or to create or configure Oracle R Enterprise users. The script can be run interactively or in batch or hybrid mode.

Installing Oracle R Enterprise Server for details
The Multitenant Container Database (CDB) feature of Oracle Database 12c is supported.
You can install support for Oracle R Enterprise Server in a multitenant environment. Oracle R Enterprise Server must be installed in a pluggable database, not in the root database.

Previously only R 3.0.1 was supported.
R 3.0.1 requirement
Oracle R Enterprise 1.4 requires R 3.0.1. As with earlier releases of Oracle R Enterprise, Oracle recommends that you use Oracle R Distribution.
Oracle R Distribution supported on Microsoft Windows
Oracle R Distribution 3.0.1 is supported on 64-bit Windows in addition to the 64-bit Linux and UNIX platforms that were supported in earlier releases.
Cairo package used for graphics display on the server
Oracle R Enterprise 1.4 uses Cairo to display graphics on an Oracle R Enterprise server. Cairo is an open source R package that creates high quality bitmap, vector, and display output.
Cairo is bundled with the Oracle R Enterprise supporting packages. With Cairo, there is no longer a need to configure an X11 server on Oracle Solaris and AIX servers.
See Table 6-2
New client packages
Oracle R Enterprise 1.4 includes two new client packages:
OREcommon — Common low-level functionality for Oracle R Enterprise
OREembed — Embedded R functionality for Oracle R Enterprise
See Table 6-1.
Enhancements to Oracle R Enterprise Server installation script
The Oracle R Enterprise Server 1.4 installation script includes these enhancements:
Configuration mode
When the configonly flag is set, the Installer performs database configuration for Oracle R Enterprise but does not copy the Oracle R Enterprise libraries to $ORACLE_HOME/lib and does not install the Oracle R Enterprise client packages.
Prompts for the RQSYS password and displays the default password
The default password is displayed so that the user can determine whether to accept the default password or specify a different password.
Enhancements to demo_user script
The demo_user script, which creates a database user for Oracle R Enterprise, can now enable an existing user for Oracle R Enterprise in addition to creating a new user.
Migration scripts
Oracle R Enterprise 1.4 includes scripts for importing and exporting Oracle R Enterprise data and schema objects from a source environment to a target environment. The source and target must have the same version of Oracle Database and Oracle R Enterprise.
