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).

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

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.

Communication

  • Communication jobs are started by a request, over a telephone line, by another system.

Autostart

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