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 stop home SRVCTL command stops all of the components that are managed by Oracle Restart in the specified Oracle home. The start home SRVCTL command starts these components. The Oracle home can be an Oracle Database home or an Oracle Grid Infrastructure home.

    When you use the home object, a state file, specified in the -statefile option, tracks the state of each component. The stop and status commands create the state file. The start command 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 status home command.

  • The stop CRSCTL command stops Oracle Restart, and the disable CRSCTL command ensures that the components managed by Oracle Restart do not restart automatically. The enable CRSCTL command enables automatic restart and the start CRSCTL command restarts Oracle Restart.
