GOAL:
What is Solaris Fixed Scheduling?
GOAL:
What is Solaris FX Scheduling?
FACT(s) (Environment):
Solaris
Solaris 10
Progress/OpenEdge Product Family
FIX:
The FX scheduler provides a scheduling policy for processes that require user or application control of scheduling priorities. The priorities of processes that run under FX are fixed. These priorities are not dynamically adjusted by the system.
This scheduling model is similar to the HP-UX SCHED_NO_AGE scheduling where process priority does not degrade over time it is fixed.
If this scheduling model is used, it should be applied identically to all Progress related processes.
This is not the default on Solaris. The default is FSS Fair Share Scheduling but FSS changes priority based on system availability and may create performance issues.
