LIGHTS Program (Super-Group Only)
ALL
turns on every sys-option at once (DISPATCHES, SYSPROCS, and PAGING).
BEAT
flashes light 0 (zero) once every second to indicate that the processor is
functioning.
Considerations
•
To run the LIGHTS program, you must have a group ID of 255.
•
Processor lights are lit for these reasons:
°
Lights 0 through 10 indicate processor usage. Light 0 is always lit (or flashing if
BEAT was specified). One additional light is lit for each 10 percent increase in
processor usage.
°
Processor light 11 is always off.
°
Light 12 is lit if the processor successfully recovered from a power
failure.When you run the LIGHTS program, light 12 is turned off in all
processors.
°
Lights 13 through 15 are lit for the reasons given in the syntax description for
DISPATCHES, SYSPROCS, and PAGING, respectively. Each light is lit for a
larger percentage of the time if more processing time is spent on the
corresponding activity.
•
When the system is cold loaded, the default LIGHTS setting is ON, ALL, BEAT.
