Enabling a power-handling program to control system activity during a power interruption

 

System software support is essentially the same for both the battery feature and the uninterruptible power supply attachment.

In some environments you may want to perform different actions when the uninterruptible power supply begins supplying power to the system or when power is fluctuating. A power-handling program can use any of the following methods to handle these situations:

To specify that you have power handling programs, change the QUPSMSGQ system value to the name of a queue you have created. The system will send the same messages to both QSYSOPR and the queue you specified. Change the QUPSDLYTIM system value to *NOMAX.

The program you use to handle the message queue must be active and must allocate the queue. If a program has not allocated the queue that is specified in QUPSMSGQ, the system will assume that no power handling program exists.
