Systems, methods, and devices are provided for transactional kernel configuration. One embodiment includes a kernel configuration tool, a system file accessible by the kernel configuration tool, and program instructions executable by the kernel configuration tool to immediately and persistently apply kernel configuration changes a manner that ensures a transactional kernel configuration change.

Transactional kernel configuration

The present invention is directed to a method and apparatus in which a UNIX operating system can be configured or tuned without rebooting the system. Advantageously, the present invention is directed to a dynamic mechanism for updating kernel parameters which is persistent and lasts across reboots. The present invention provides a dynamic kernel tunable framework for changing tunables in a kernel without rebooting. A graphical user interface displays and is used to change graphical values and settings of dynamic tunables.

Dynamic kernel tunables

A method for testing a service that provides interface functions having no user space interaction and that is runs in a kernel space of an operating system. The method includes loading into the kernel space a dynamically loadable kernel module (DLKM) containing a pseudo device driver having interface commands corresponding to the interface functions of the service to be tested, invoking the interface commands to exercise the interface functions to be tested, and unloading the DLKM module.
