Chapter 10. Running Operating System Commands

Oracle provides a number of facilities for running operating system commands from the database server — some intentional and others "hacks." Commands can be executed via PL/SQL, Java, and default packages, and by manipulation of the server parameters using the ALTER SYSTEM command. Needless to say, the relevant high-level permissions are required to run OS commands, but earlier chapters have shown that gaining such privileges is not a difficult task.
