Defining Jobs

  • Jobs are chunks of Work done on the 400.
  • Jobs are basic units of work on the 400.

Job Names

  • Each job has a unique name
  • A job name has 3 parts
    • Job Number
    • User Name
    • Job Name

We need to know the individual naming ingredients when using Green Screen Commands to access info about particular Jobs.

Types of Jobs

  • Each job requires some system resources from a pool that is made available.
  • DSPJOBTBL to check on those resources and see if we need more added to lower risk of Degradation.

System Jobs

  • System jobs begin with the letter Q.

Spooling Jobs

  • System provided print programs (writers).
    • Start = Start Writer Command
    • End = End Writer Command

User Jobs

Interactive

  • Interactive jobs usually start when a user signs onto work station display of Green Screen, and end when the user signs off the work station.
    • Start = Sign on
    • End = Sign off
  • Each time user signs on, that is a new job.

Batch

  • Batch jobs are normally run by submitting requests for processing of data by programs that do not need to interact with the user.
  • These requests go into a JOBQ to run as system resources are available.
  • Start = Placed on JOBQ
  • End = EOJ End of Job

Communication

  • Communication jobs are started by a request, over a telephone line, by another system.
    • Start = Request from Remote System
    • End = Same as batch or interactive

Autostart

  • Typically Autostart jobs are launched with the start of some subsystem to handle housekeeping chores associated with the function of that subsystem.
    • Start = Start subsystem
    • End = EOJ End of Job
