The SHUTDOWN command stops the z/OS Master Controller after shutting down each of the process subtasks. The z/OS Master Controller will remain active until each of the process subtasks have been shutdown.
The SHUTDOWN command has two levels:
- NORMAL - Allows each of the process subtasks to stop normally before the Master Controller stops. This is the default unless the P command is entered from the operator’s console, which is interpreted as a STOP FORCE command.
- FORCE - Stops all process subtasks immediately by detaching the TCB of the process(es). This is the default if the P command is issued from the operator’s console. Otherwise, the FORCE keyword must be specified after the STOP command.

Example
