Scheduler Planning, Configuration,
and Management
This section describes how to work with the scheduler:
Planning Schedulers
Planning your organization’s schedulers is a three-stage process that involves:
Task 1. Compile Job Information
To start planning schedulers, gather information about jobs whose submission,
execution, and management you want placed under NetBatch control. This information
helps you determine how many schedulers you need, the schedulers’ attributes, and
their class and executor configurations.
This table lists the information you need for each job you identify. Record information
about your jobs in a table similar to Figure 3-1 on page 3-2. For a detailed job planning
procedure to help you get this information, see Planning Procedure on page 4-1.

Information
required Function
Job category Describes the job or job type (for example, COBOL compiles)
Executor program Specifies the job’s executor program (for example, TACL or NBEXEC)
Executor-program
priority
Specifies the execution priority of the job’s executor-program process
Executor-program
nodes
Specifies the nodes on which the job runs
CPU-bound or
I/O-bound
Specifies whether job processing is CPU-bound or I/O-bound. (CPU-
bound processing occurs predominantly in a CPU, with few references
to I/O resources such as disk files. I/O-bound processing places a
heavy demand on I/O resources, but few demands on CPU resources.)
