Disable CRS

Disable CRS

With the article “Disable CRS,” we provide the command to disable CRS upon operating system reboot to disable autostart.

The command is just one, but we advise executing it with caution, as with any command on server platforms, of course. Disabling CRS disables CRS on the system and consequently its automatic startup.

This stops the high availability service, precisely because upon reboot, the instance and its related resources on a node would remain DOWN.

So, in the case of server maintenance activities, including OS updates or a change of some HW component, if multiple reboots are required, you’ll need to disable automatic startup with the following command.

The command to disable CRS to be executed with the root user is:

crsctl disable crs

Wasn’t it simple? Perfect! 🙂
