2.1.1 About Connecting to the Database

Oracle Machine Learning for R client components connect an R session to an Oracle Database instance and the OML4R server components.

The connection makes the data in a database schema available to the R user. It also makes the processing power, memory, and storage capacities of the database server available to the R session through the OML4R client interface.

The following topics discuss connecting and disconnecting an R session to an Oracle Database instance:

• About Using the ore.connect Function
  To begin using OML4R, you first connect to a schema in an Oracle Database instance with the ore.connect function.
• About Using the ore.disconnect Function
  To explicitly end the connection between an R session and the Oracle Database instance, invoke the ore.disconnect function.
