1442 z/VM: CP Commands and Utilities Reference
Use SLEEP to stop your virtual machine for a specified period of time. When the
specified period elapses, your virtual machine automatically resumes processing.
nn SEC
nn MIN
nn HRs
identifies the number of seconds, minutes, or hours, measured by the
time-of-day clock, that your virtual machine is to remain stopped. The value nn
can be any decimal number from 00 through 99. If you specify no time unit, CP
assumes that nn indicates minutes.
ATTN
specifies that if the SLEEP command with a time interval is issued through a
DIAGNOSE X'08' instruction, the return code indicates whether the virtual
machine restarted because the time interval expired (RC=0), or because an
attention was signaled (RC=1457).
1. During the dormant period, the virtual machine does not run, but connection
time is still counted.
2. Messages continue to be displayed even though your virtual machine is in the
dormant state.
3. You can start your virtual machine at any time by pressing the ENTER key. If
you specify a sleep interval in the command line, your virtual machine awakens
automatically when the specified interval has elapsed.
4. If you do not specify an interval, your virtual machine remains dormant until you
press the ENTER key.
5. If you enter the SLEEP command from a CP environment, you will return to the
CP environment when the time interval has elapsed, or when you press the
ENTER key.
6. If you enter the SLEEP command while in virtual machine environment, the end
of the time interval or pressing ENTER returns your display to virtual machine
mode without entering the CP environment.
7. The SLEEP command, with the time interval, is a convenient way to delay or
schedule the execution of certain jobs that could be run more efficiently at a
later time (for example, second shift).
