Setting the kernel.panic tunable

The topic applies to SF Oracle RAC.

By default, the kernel.panic tunable is set to zero. Therefore the kernel does not restart automatically if a node panics. To ensure that the node restarts automatically after it panics, this tunable must be set to a non-zero value.

To set the kernel.panic tunable

  1. Set the kernel.panic tunable to a desired value in the /etc/sysctl.conf file.

    For example, kernel.panic = 10, will assign a value 10 seconds to the kernel.panic tunable. This step makes the change persistent across restarts.

  2. Run the command:

    sysctl -w kernel.panic=10

    In case of a panic, the node will restart after 10 seconds.
