A user-defined routine (UDR) written in C language or in the Java language is called an external routine. External routines must include the External Routine Reference clause that specifies a shared-object filename. By default, only users to whom the DBSA has granted the built-in EXTEND role can create or drop an external routine. See the section Granting the EXTEND Role (IDS) for additional information about this feature.
