This preface describes changes in Oracle R Enterprise Installation and Administration Guide for Release 1.4.
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.
See Section 3.5, "Installing Oracle R Distribution on Windows".
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 Section 6.1.3.2, "Oracle R Enterprise Supporting Packages"
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
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.
See Section 4.1.3, "About the Oracle R Enterprise Server Installation Script".
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.
See Section 7.1, "Creating a Database User for Oracle R Enterprise".
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.
