Running the z/VM Operator's Virtual Machine

When you bring up the z/VM® system, CP automatically logs on the primary system operator at the z/VM primary system console. The primary system console is a display. Your installation defines its device number on the RDEVICE statement in the system configuration file.

Your installation defines the primary system operator's user ID on the SYSTEM_USERIDS statement in the system configuration file. Your installation may also have defined other user IDs for you to use when you perform special operations tasks. For example, an installation often has a spooling operator who controls the installation's printers. If you are the spooling operator, you often use another user ID at another console.

However, the primary system operator has special privileges. If you are responsible for controlling z/VM, you usually use the user ID of the primary system operator.

In addition to having special CP command privileges, the primary system operator's virtual machine has default settings that differ from those of other users. For example, the primary system operator's default setting for the TERMINAL MODE command is CP rather than VM. And the initial setting of the SET RUN command is ON rather than OFF.

Otherwise, the primary system operator's virtual machine is the same as any other virtual machine.
