2 (5650-ZOS).
Purpose of this information
This information contains planning information for MVS™ operations. It describes how to define and
use multiple console support (MCS) consoles, SNA Multiple console
support (SMCS) consoles (as of z/OS V1R1),
and extended MCS (EMCS) consoles. It also describes how to manage
messages and commands in an MVS single-system
or sysplex environment.
Who should read this information
System programmers who plan MVS operations
and persons who administer the security procedures for their installations
should use this information. The information assumes that the user
understands the installation's hardware and software, and also understands
the general organization and functions of MVS.
Users should also have a good understanding of parmlib and how to
use it.
How to use this information
The information is organized as follows:
- Planning MVS operations describes setting operations
goals for an MVS environment.
It provides a brief introduction to multiple console support (MCS)
consoles, SMCS consoles, and extended MCS consoles.
- Defining console configuration describes how to define
an MCS and SMCS console configuration. It describes how to define
a device as a console and how to define console functions in CONSOLxx
of parmlib. It also provides information to plan for console recovery,
console security, and system logging.
- Managing messages and commands describes how to manage
messages and commands for consoles in an MVS environment.
It includes information about the message processing facility (MPF),
the action message retention facility (AMRF), installation exits to
modify messages and commands, and message translation using the MVS message service (MMS).
- Planning for operation tasks describes how to plan for
basic MVS operator tasks like
initializing a system and operating MVS on
a day-to-day basis.
- Examples and MVS planning aids for operations provides examples of defining
a console cluster to handle message traffic in an MVS system and defining a console configuration
in a two-system sysplex. It also contains reference information to
help you in your planning.
