Hi All,
Thank you for the responses. We in the lab have consolidated the
responses and categorised them as below.
Response 1: Make it available to only MANAGER.SYS, not also to
OPERATOR.SYS.
No of votes: 13.
Response 2: Ability to tell the system not to DUMP, but just BOOT.
No of votes:2
Response 3: New capability for shutdown like SD.
No of votes:1
Response 4: Lockword on the command/ACDs.
No of votes:3
Response 5: Look for a new file SYSSHUT.PUB.SYS and then execute.
No of votes:2
Response 6: " I would like to see it restricted to console, but allowable.
The suggestion of tying it with MANAGER.SYS & OPERATOR.SYS
bothers me a bit in that not every one uses these default
users".
No of votes:1
Response 7: Confirmation to be got before that shutdown command executes.
No of votes:2
Response 8: Command available only to SM users & should be only a console .
command.
No of votes:3
While it is possible to implement most of the requests, considering the
effort involved to incorporate these requests, we like to maximise on
the critical needs of most of out customers. Hence we propose to implement
the one which got the maximum # of votes ie, SHUTDOWN command available
only to MANAGER.SYS.
Hope this is acceptable to most of our customers.
Once again your valuable inputs are welcome
thanx & regards

Note: Sorry for the incorrect reference to AUTOBOOT feature in the original
posting. It is available in the base os. But FORMAT command is only
available with the AUTORESTART product.

Hi All,
We in CSY Lab are investigating the feasibility of providing a
SHUTDOWN command on the CI prompt in MPE/iX. As part of this
investigation we would like to know customer's expectations and
requirements regarding this command.
We have attached a brief description of what we think is essential
for this command. Please spend some time to review this command
and send us your comments/suggestions either directly to us through
email or to the 3000-L mailing list.
Thanks

OBJECTIVE:
=========
Presently MPE/iX supports the =SHUTDOWN with console interrupt ([CTRL][A]).
The =SHUTDOWN command performs an implicit =LOGOFF of all sessions,
including the session logged at the system console. The CPU halts,
and console interrupt ([CTRL][A]) is ineffective .
The objective of this enhancement is to provide shutdown mechanism with a
reboot option similar to HP-UX.
The enhancement provides a :SHUTDOWN command on the CI prompt, with
a RESTART option which shuts down the system completely and reboots
automatically.
EXISTING FUNCTIONALITY:
======================
=SHUTDOWN
Initiates a shutdown of MPE/iX.
syntax
=SHUTDOWN [system ]
[terminal]
[dtc ]
[tape ]
[disk ]
[network ]
[other ]
The machine will be completely shutdown. It needs operator
intervention. CTRL-B ,TC or RS is needed to boot the system.
New CI Command :
================
:SHUTDOWN
Initiates a shutdown of MPE/iX.
syntax
:SHUTDOWN [system ];RESTART
[terminal]
[dtc ]
[tape ]
[disk ]
[network ]
[other ]
:SHUTDOWN
will shutdown the system completely.
:SHUTDOWN;RESTART
will shutdown the system completely and reboot the system
automatically to ISL> prompt.
This command can be issued only by users with system manager (SM)
or system supervisor (OP) capability.
This RESTART option is not applicable to other types of
devices such as terminal, dtc, tape etc.
With AUTOBOOT:
With this :SHUTDOWN ;RESTART option, we are also proposing to
give AUTOBOOT functionality as part of the solution. Currently
AUTOBOOT is available only with AUTORESTART product.
With AUTOBOOT configuration, the system can be restarted automatically.
In simple terms, AUTOBOOT configuration file specifies the command
to be RUN in ISL> prompt when the control transfers to ISL prompt. Hence,
when :SHUTDOWN ;RESTART results in ISL, it automatically executes the
command in AUTOBOOT file (typical command is :START -R NORECOVERY ...).
Before executing the AUTOBOOT sequence, there exists a 10 seconds window
to abort the AUTOBOOT sequence, in case operator/manager wants to perform
some other operation.
Sample steps for creating the Autoboot file and configuration
=============================================================
1. :SHUTDOWN;RESTART with AUTOBOOT feature
------------------------------------------
The AUTOBOOT feature provides a FORMAT utility that enables user to create
a specially formatted file that contains the special sequence of startup
commands. The system automatically executes these commands in sequence
during system startup if this feature is activated.
Building a AUTOBOOT file
-------------------------
* Create a file called AUTOIN which contains the
"START -R NORECOVERY" command .
* Run FORMAT.PUB.SYS. Output will be in a file called AUTOOUT
in the same group.
* Copy AUTOOUT,AUTOBOOT.MPEXL.SYS
* Set the autoboot file with the SYSGEN utility.
:SYSGEN
>sy
>aa file=autoboot.mpexl.sys;type=disc
>hold
>exit
>keep
>tape verbose
* Perform a configuration UPDATE to your system with the CSLT tape
created under SYSGEN
* After UPDATE is done, use the ISL AUTOBOOT command to
enable the autoboot feature.
At the ISL prompt enter:
ISL> AUTOBOOT ON
* Use the START command with the -R option, to start the system.
At the ISL prompt enter:
ISL> START -R start_options
If the -R option is not used with the START command the autoboot feature
wil not be enabled.
Once the above steps are complete & the autoboot feature is enabled, the
commnd :SHUTDOWN;RESTART will completely shutdown the system and the
startup needs no operator intervention.
