While logged on as a superuser on Linux, check the etc/inittab file for these
lines:
# z/VM or LPAR is shutting down
ca:12345:ctrlaltdel:/sbin/shutdown -h now
Important: Be sure the shutdown command shuts down Linux (-h) rather than
restarting it (-r).
You are done.
Setting up the programmable operator
This topic describes the programmable operator facility and shows you how to set
it up.
Overview of the programmable operator
The programmable operator facility increases the efficiency of z/VM system
operation and allows operation of systems in a distributed processing environment.
The facility intercepts all messages and requests directed to the z/VM operator
virtual machine and handles them according to programmed actions. Some
messages are simply recorded for future reference, others are acted upon
programmatically, and others are sent to a real operator to handle.
The programmable operator facility runs in a CMS virtual machine. Although it
can run in any virtual machine, because of its programmed capability to log,
handle, or redirect messages, it is most commonly run in the CP system operator’s
virtual machine.
The programmable operator facility compares all messages directed to it against
entries listed in a
routing table , a CMS file. When a match occurs, the prescribed
action is performed. If there is no match, no action is performed. Any messages
requiring a real operator’s response or action are sent to the defined operator at
another console, called the
logical operator console. If the default action is to log
messages, all messages are logged in a CMS log file . The benefit is that the real
system operator sees only important messages, while all messages are recorded for
auditing.
Example: As shown in Figure 8 on page 89, the OPERATOR user ID is defined as
the CP system operator when the CP system is configured. Set up the
programmable operator to run in the OPERATOR virtual machine and establish
another virtual machine with a user ID of LGLOPR. In the routing table, specify
LGLOPR as the logical operator. Now any CP or virtual machine user messages
sent to the system operator virtual machine can be handled or filtered by the
programmable operator or routed to the LGLOPR user ID. A real system operator
logs onto LGLOPR and monitors messages sent to that virtual machine.
