JES2 Job Controls I

This course covers the services provided by JES2. It reviews the purpose of a job entry system in the MVS environment and describes the services provided by JES2. The basic structure of JES2 and the functions it performs are discussed along with remote job entry (RJE), network job entry (NJE) and additional facilities. The course covers the JES2 control statements for establishing job parameters and communicating with the operator. SYSOUT data processing is discussed as well as the various ways to control how SYSOUT data is processed. The course describes how to route jobs for execution on another processor in a network, the types of JES2 commands and the restrictions typically placed on a command entry from remote terminals. This course is written to JES2 version 5.2.

Job Controls I training covers such topics as:

Introduction to JES2
Controlling JES2 Processes
JES2 Communications
Job Control Commands

This course is designed for operators with previous JES2 experience

JES2 System Control I
Description
This course covers the JES2 and MVS commands for controlling batch jobs, started tasks, and
time-sharing users. Manipulating jobs in the queues and controlling JES2 initiators are also described.
The course describes JES2 initiators, the commands used to control them, and how JES2 initiators
select work from the execution queues. Also discussed are commands to change the class or
priority of jobs in the JES2 execution queue. The course provides an introduction to the operating
system and its components, describes the stages of job processing after a job has been selected for
execution, explains the execution of started tasks and the services provided to TSO users by MVS
and JES2. MVS and JES2 commands used to control jobs in execution are discussed as well as how
to cancel batch jobs, started tasks, and time-sharing users in execution. The course describes the
commands used to start, modify, stop, cancel, and monitor the execution of a started task. It
explains how to send messages to time-sharing users, the characteristics of a multi-access spool
complex, and the concept of system affinity, as well as how programmers can specify which
processors in the complex are eligible to execute a job. Finally, the course explains operational
considerations for JES2 network job entry environments, how to route jobs and SYSOUT data to other
systems in the network, and how to determine the status of jobs at other systems. This course is
written to JES2 version 5.2.
Audience
