Operator Console Display

Consoles provide a means of communication between the operator and the computer. There are two types of consoles: hard copy, which print on paper, and CRT displays, which have a cathode ray tube (CRT) or plasma screen.

Although it is possible to enter system commands from other types of devices, the operator console is the tool used to initiate system initialization (IPL), vary hardware equipment online and offline, issue JES commands, execute programs, or submit JCL. Because consoles are the primary operator communications device, they must be physically secure from access by unauthorized personnel.

Review inactive and active consoles because inactive consoles can be made active with the VARY console command.

The Operator Console Display follows with sample data. This screen shows you:

• The number of z/OS operator consoles defined to the system
• How to track the physical location of each console
• Command groups that can be issued from the messages that each console can receive
• Active Parmlib members for specific consoles
• For consoles in a sysplex:
  • The logical name and alternate logical name of the console
  • The user who is signed on to the console, if applicable
  • The name of any alternate group the console is part of
  • The system ID of the console
  • The Sysplex ID of the console

The operator console is the primary device that controls the z/OS operating system. Because passwords and access control software do not protect consoles, ensure that they are physically secure from access by unauthorized personnel. Also, protect operator commands.
