This information supports z/OS (5694-A01).
Purpose of this information:
This information describes how to use MVS™ system
operator commands for the z/OS (5650-ZOS)
operating systems. Although you can also perform many of the tasks
described in this information using JES2 or JES3 commands, this information
describes only the MVS (base control program) system
commands. For information about commands for other z/OS elements,
such as communications server (IP and SNA), DFSMS, JES2, JES3, and RACF®, see z/OS Information Roadmap. For information about commands for other software products that
run on z/OS, see z/OS® Software Products Collection, SK3T-4270.
Who should read this information:
This information is intended for anyone using a console and system
commands to control the operating system. This information assumes
that the user understands the hardware controls and features of the
installation. It also assumes that the user understands the general
organization and functions of a z/OS operating
system.
How to use this information:
To describe the basic tasks within these general tasks and to provide
a convenient system commands reference, this information is organized
as follows:
- System operations, describes the tasks of running
the system from the time the system comes up to the time the system
goes down for a normal or abnormal reason.
- System Reconfiguration, describes the reconfiguration actions
of hardware units and partitions. It also shows how to physically
or logically reconfigure the hardware units of a system; and for a
partitionable processor complex, how to partition the complex into
two sides or merge the two sides together.
- z/OS operator console operations, describes the consoles that MVS supports as operators' consoles. Console characteristics and operations describes the operations and characteristics that you cannot define, including the operations that are common on all
operator's consoles.Defining and changing console characteristics describes the
console characteristics that you can define, including the
commands that operators and system programmers can use to tailor the
consoles and console operations to the installation's requirements. Defining and changing console characteristics also describes how to restrict the use
of system commands based on which operator issues the command and/or
which MCS or SMCS console the operator uses.
- MVS system commands reference, summarizes the function, syntax,
and parameters of all the MVS system commands that you can
use to control both the system and the MCS and SMCS consoles.
