即Oracle 11gR2 New Features Oracle Restart

Oracle Restart improves the availability of your single-instance Oracle database. Oracle Restart automatically restarts the database instance, the Automatic Storage Management (ASM) instance, the listener, and other components after a hardware or software failure or whenever your database host computer restarts. Server Control (SRVCTL) is the command line interface to manage Oracle processes that are managed by Oracle Restart on a standalone server.
