6.1 About Oracle R Enterprise Client

Oracle R Enterprise includes several components that must be installed separately on each client computer.

Components of Oracle R Enterprise Client

R (See Installing R for Oracle R Enterprise)
Oracle Database Client Software
Oracle R Enterprise packages
Oracle R Enterprise supporting packages

The Oracle R Enterprise client components can be installed in any order:

6.1.1 About Oracle Database Client Software

ROracle, one of the supporting packages used by Oracle R Enterprise, requires an installation of Oracle Database client software to enable communication between an R client and an Oracle database. The Database client can be either Oracle Database Client or Oracle Database Instant Client:

Oracle Database Client is distributed with Oracle Database and is based in the Oracle home of the database.
Oracle Database Instant Client is a free, standalone implementation of Oracle Database Client. Oracle Instant Client is not based in an Oracle home directory and requires less disk space than Oracle Database Client.

6.1.2 About the Oracle R Enterprise Packages

The Oracle R Enterprise packages are a set of Oracle proprietary packages that support Oracle R Enterprise.

These packages are required on each client computer and on the server computer that hosts Oracle R Enterprise Server. On the server, the Oracle R Enterprise packages are installed automatically by the Oracle R Enterprise Server installation script.

Note:

The version of the Oracle R Enterprise packages on the client must match the version of the Oracle R Enterprise packages on the server.
