See:
"Installing Oracle R Enterprise on Exadata" in Oracle R Enterprise Installation and Administration Guide.

- The list of RPMs required for Oracle R Enterprise is now provided for both Oracle R Distribution 3.1.1 and 3.0.1 on both Oracle Linux 5 and Oracle Linux 6.

See:
"Installing Oracle R Distribution on Linux Using RPMs" in Oracle R Enterprise Installation and Administration Guide.

New Features in Oracle R Enterprise 1.4.1

Oracle R Enterprise 1.4.1 introduces the following new features:

- 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.

See Also:
"Installing Oracle R Enterprise Server" in Oracle R Enterprise Installation and Administration Guide

- 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. The server must be installed in a pluggable database, not in the root database.

See Also:

- Oracle Database Concepts for an introduction to multitenant architecture.

- Oracle Database Administrator's Guide for information about managing a multitenant environment.

- Oracle R Enterprise 1.4.1 includes two new supporting packages: arules and statmod. The Oracle R Enterprise 1.4.1 supporting packages are:

arules 1.1-3
cairo 1.5-5
DBI 0.2-7
png 0.1-7
ROracle 1.1-12
statmod 1.4.20

"About the Oracle R Enterprise Supporting Packages" in Oracle R Enterprise Installation and Administration Guide

- The ore.glm function now accepts offset terms in the model formula and the function can now be used to fit negative binomial and tweedie families of generalized linear models.

- The ore.sync function has an additional optional argument, query, that creates an ore.frame object from an optimized SQL SELECT statement without creating a view in the database. You can use this argument to create a query even when you do not have the CREATE VIEW system privilege for the current schema.

See Also:
"Using ore.sync to Add ore.frame Proxy Objects to an R Environment" in Oracle R Enterprise User's Guide

- The new global option for serialization, ore.envAsEmptyenv, specifies whether referenced environments in an object should be replaced with an empty environment during serialization to an Oracle Database. This option is used by the following functions:

- ore.push, which for a list object accepts envAsEmptyenv as an optional argument

- ore.save, which has envAsEmptyenv as a named argument

- ore.doEval and the other embedded R execution functions, which accept ore.envAsEmptyenv as a control argument.

The default values of the above arguments are regulated by the global option ore.envAsEmptyenv, but by using the argument you can override the global option value for a function.

About Oracle R Enterprise and Oracle Database

Oracle R Enterprise 1.4.1 supports Oracle Database 11.2 and 12.1. However, both versions of Oracle Database ship with earlier releases of Oracle R Enterprise. If you are using an earlier release of Oracle R Enterprise, you should upgrade to release 1.4.1.

About Oracle R Enterprise and R

Oracle R Enterprise 1.4.1 requires R 3.0.1 or 3.1.1. Oracle recommends that you use Oracle's own distribution of R with Oracle R Enterprise. Oracle R Distribution automatically resolves dependencies and offers other significant advantages. See "Why Oracle R Distribution?" in Oracle R Enterprise Installation and Administration Guide for details.

Oracle R Distribution is available for download free of charge from this website:

http://www.oracle.com/technetwork/database/database-technologies/r/r-distribution/downloads/index.html

If you use open source R with Oracle R Enterprise, then you must build it from source. Follow the instructions in "Open Source R and Oracle R Enterprise" in Oracle R Enterprise Installation and Administration Guide.

Known Issue in Oracle R Enterprise 1.4.1

Bug Number: 18386225

Title: R:ORE: OLDER LIBS NEED TO BE CLEANED ON ORE UPGRADE FROM 1.3.1 TO 1.4

Description: The uninstall script for Oracle R Enterprise Server 1.3.1 removes the following libraries:

libimf.so
libintlc.so
libiompprof5.so
libiompstubs5.so
libirc.so
libomp_db.so
libsvml.so

Starting with release 1.4, these libraries no longer ship with the product. The uninstall script for Oracle R Enterprise Server 1.4 does not remove them. If you upgrade from 1.3.1 to 1.4, then uninstall 1.4 and reinstall 1.3.1, the installation fails.

Workaround: Manually remove the libraries before reinstalling Oracle R Enterprise 1.3.1 if you have already upgraded and uninstalled 1.4.
