Stopping and Restarting Oracle Restart for Maintenance Operations
When several components in an Oracle home are managed by Oracle Restart, you can stop Oracle Restart and the components managed by Oracle Restart in the Oracle home.
You can also disable Oracle Restart so that it is not restarted if the node reboots. You might need to do this when you are performing maintenance that includes the Oracle home, such as installing a patch. When the maintenance operation is complete, you can enable and restart Oracle Restart, and you can restart the components managed by Oracle Restart in the Oracle home.

Use both the SRVCTL utility and the CRSCTL utility for the stop and start operations:
The
stophomeSRVCTL command stops all of the components that are managed by Oracle Restart in the specified Oracle home. ThestarthomeSRVCTL command starts these components. The Oracle home can be an Oracle Database home or an Oracle Grid Infrastructure home.When you use the
homeobject, a state file, specified in the-statefileoption, tracks the state of each component. Thestopandstatuscommands create the state file. Thestartcommand uses the state file to identify the components to restart.In addition, you can check the status of the components managed by Oracle Restart using the
statushomecommand.
The
stopCRSCTL command stops Oracle Restart, and thedisableCRSCTL command ensures that the components managed by Oracle Restart do not restart automatically. TheenableCRSCTL command enables automatic restart and thestartCRSCTL command restarts Oracle Restart.
