The following kernel parameters control aspects of process scheduling:
maxclsyspri
maxclsyspri is the maximum global priority of processes in the system class. When the kernel starts system processes, it assigns their priorities using the value of maxclsyspri as a reference point. maxclsyspri must have a value of 39 or greater, because the kernel assumes that the total range of system class priorities is at least 40.
If you change this parameter, you must rebuild the scheduling class tables with values that correspond to the maximum priorities that you assign.
sys_name
sys_name is the character string name of the system scheduler class. The default value of sys_name is SYS.
