2.2 Using EXTPROC with Embedded R Execution

Oracle Database uses an external procedure agent named extproc to support external procedures.

An external procedure is a procedure invoked from a program that is written in a different language. OML4R uses extproc to support embedded R execution.

• About EXTPROC
  When an application invokes an external procedure, Oracle Database starts an extproc agent.
• About EXTPROC Configuration for OML4R
  OML4R uses the default configuration of extproc.
• Troubleshooting EXTPROC
  Calling an OML4R embedded R function may result in an error if a database configuration problem exists.
