KEY HIGHLIGHTS:
- What is a JES?
- How JES2 Fits into the OS/390 System
- Relationship of JES2 to JCL and Submitted Jobs
- JES2 Compared to JES3
- Overview of JES2
- How does JES2 manage its work?
- Where does JES2 store its data, and how does JES2 provide integrity
- What is spooling
- What is checkpointing¦
- What processing configurations does JES2 support
- What is a multi-access spool complex
- What is poly-JES
- What is remote job entry
- What is network job entry?
- During the life of a job, what processing does JES2 do for OS/390
- What are some of the major JES2 functions that make it special?
- Review the Phases of Job Processing
- Review the six phase of Job
- Input Phase
- Conversion Phase
- Processing Phase
- Output Phase
- Hard-Copy Phase
- Purge Phase
- Explain the status of jobs:
- Waiting to run - conversion queue
- Currently running - execution queue
- Waiting for their output to be produced - output queue
- Having their output produced - hard-copy (print/punch) queue
- Waiting to be purged from the system (following completion of all processing) - purge queue.

- Tailoring Your JES2 System
- How can JES2 be tailored at initialization to meet my installation's needs ?
- Do I need to get so involved in customizing JES2 that I need to write 'operating system' code?
- What other means can I use to enhance JES2 if it does not meet all my specific processing needs?
- What are JES2 'table pairs'
- What's the difference between an IBM-defined exit and an installation-defined exit?
- Interacting with JES2
- Communicating with JES2?
- Operator control over JES2
- Automating routine processing needs
- JES2 problems
- Diagnosis and recovery?
- Stopping and Restarting & JES2 Commands
- Operator commands can be used to:
- Add function and functional subsystems
- Modify previously defined processing, such as: output definition, the dynamic alteration of the checkpoint definition, enabling installation-defined exits, offload devices, printer and punch characteristics, and job characteristics
- Delete function, and network systems, exits, and diagnostic traces
- Start, stop, and halt devices under JES2's control
- Assign units to local printers, punches, card readers, and lines or reassign units to these devices
