Roopalini-
As a starting point, you can examine ResUsage:
Calculating parallel efficiency using ResUsage
The ResNode macro (DBC.ResGeneralInfoView) provides the following:
/* Parallel efficiency of total pct of time CPUs were busy */
(AVG(CPUBusy)*100)/NULLIFZERO(MAX(CPUBusy))
(FORMAT 'ZZ9', TITLE 'CPU//Eff// %'),
/* Parallel efficiency of the logical device IOs */
AVG(LogicalDeviceIOKB)*100 / NULLIFZERO(MAX(LogicalDeviceIOKB))
(FORMAT 'ZZ9', TITLE 'Ldv//Eff// %'),
