The IBM i Job Model: Jobs, Queues, Subsystems

Every program you run on IBM i executes inside a job, and every job runs inside a subsystem — understanding that structure is the difference between guessing why something is slow

What you'll be able to do

1. 1Define what a job is and how it differs from a program
2. 2Explain how job queues and subsystems control where and how work runs
3. 3Distinguish between interactive, batch, and system jobs
4. 4Locate and inspect an active job's status using standard commands
