An external procedure is a procedure invoked from a program that is written in a different language. Oracle Database uses an external procedure agent named
extproc to support external procedures. Oracle R Enterprise uses
extproc to support embedded R execution.
When an application invokes an external procedure, Oracle Database starts an
extproc agent. The application uses the network connection established by Oracle Database to pass instructions to the agent for executing the procedure. The agent loads a DLL or shared library, runs the external procedure, and passes back to the application any values returned by the external procedure.
Oracle R Enterprise uses the default configuration of
extproc agent is spawned directly by Oracle Database, and no configuration changes are required for either
extproc supports any external procedure call. If you want to only allow external procedure calls for Oracle R Enterprise, you can edit the
EXTPROC_DLLS environment variable in
The following statement on a Linux or UNIX system sets
EXTPROC_DLLS to only execute external procedures for Oracle R Enterprise:
extproc to service any external procedure, set
ANY or simply leave it blank (the default).
