Batch

What is the required batch throughput or turnaround for various job classes?
How much service do batch jobs require, and what service rate is needed to meet the turnaround requirement?
- An RMF™ workload report or reduction of SMF data in type 5 or type 30 records will provide the average service consumed by jobs of different classes. Based on service definition coefficients of CPU=10.0,IOC=5.0,MSO=3.0,SRB=10.0; the following approximations can be made:
  - Short jobs use 30,000 service units or less.
  - Long jobs use more than 30,000 units.
What is the average number of ready jobs?
- Most likely, this is the number of active initiators. A few extra initiators may be started to decrease turnaround times.
