5.1 About Oracle Machine Learning for R on Exadata

Exadata is an ideal platform for OML4R.

The parallel resources of R computations in OML4R take advantage of the massively parallel grid infrastructure of Exadata.

Note:

The version of OML4R must be the same on the server and on each client computer. Also, the version of R must be the same on the server and on each client computer. See the Create a Database User for Oracle Machine Learning for R for supported configurations.

To install OML4R on Exadata:

1. On each node:

   • Install Oracle R Distribution

   • Verify and configure the environment

   • Install OML4R Server and the supporting packages

2. On the first node only, create an OML4R user, if desired. Alternatively, configure an existing database user to use OML4R. See .

You can simplify the process of installing OML4R on Exadata by using the Distributed Command Line Interface (DCLI).
