Controlling system shutdown using a power-handling program

 

Power-handling programs can minimize interruptions during a power loss. You should use a power protection device, such as an uninterruptible power supply, with your power-handling program.

Power protection (for example, uninterruptible power supply) devices help provide energy to the system when utility power is temporarily interrupted. The energy that is provided helps prevent system functions from ending abnormally. The controlled shutdown mechanisms help the system shut down as smoothly as possible, minimizing adverse impacts on initial program load (IPL) time.

You can tailor the CL program examples to your specific system requirements, as well as test the power-handling program that you created.
