Oracle Restart improves the availability of your Oracle Database. When you install the Oracle Grid Infrastructure for a standalone server, it includes both Oracle ASM and Oracle Restart. Oracle Restart runs out of the Oracle Grid Infrastructure home, which you install separately from Oracle Database homes.
Oracle Restart provides managed startup and restart of a single-instance (non-clustered) Oracle Database, Oracle ASM instance, service, listener, and any other process running on the server. If an interruption of a service occurs after a hardware or software failure, Oracle Restart automatically takes the necessary steps to restart the component.
With Server Control Utility (SRVCTL) you can add a component, such as an Oracle ASM instance, to Oracle Restart. You then enable Oracle Restart protection for the Oracle ASM instance. With SRVCTL, you also remove or disable Oracle Restart protection.
