Monitoring the System from the Console
You monitor the system to ensure appropriate shared use of the system, to
respond to tape reply requests, to respond to place special forms on the
printers, and to keep informed about disk storage and other resource
usage. Usually the system administrator performs these routine functions
from the system console.
The system console is the terminal that is directly connected to the
computer box. From it the system administrator typically monitors
messages from users, requests for loading tapes, and various information
about system use. The console may appear to be a simple terminal, yet
its function is critical to the operation of the system. The console
should not be turned off while the system is operating. For information
on turning off the console, or the computer, refer to the "System
Shutdown" section of this chapter.
To identify the console
It is critical to know which terminal is the system console. The console
terminal must not be turned off while the system is in operation. It is
the only input device for a special set of commands that monitor and
control the system.
For the HP 3000 Series 9X8LX, the console is physically connected to the
computer. Its logical device (LDEV) number is usually LDEV 20, but your
system could be different. This console may also run software
applications, but its role as system console is critical to keeping the
system operating.
1. Enter the CONSOLE command to identify the LDEV number associated
with the console on your system:
:CONSOLE Return
CONSOLE IS CURRENTLY ASSIGNED TO LDEV 20
This command is limited to those users who have been granted its
use.
2. Enter the SHOWME command and compare LDEV numbers to ensure that
the terminal that you are on is the console. On the SHOWME screen
find this LDEV number after $STDIN and $STDLIST. In the following
example, the terminal from which the SHOWME command has been
issued is LDEV 20.
___________________________________________________________________________
| |
| |
| :SHOWME Return |
| |
| USER: #S118,ROSEN.PAYROLL (NOT IN BREAK) |
| RELEASE: C.45.00 MPE/iX HP 31900 B.57.06 USER VERSION: C.45.00 |
| CURRENT : WED, DEC 15, 1993, 3:58 PM |
| LOGON : WED, DEC 15, 1993, 3:57 PM |
| CPU SECONDS: 2 CONNECT MINUTES: 1 |
| $STDIN LDEV: 20 $STDLIST LDEV: 20 |
| |
___________________________________________________________________________
3. If the terminal's LDEV number is not the same as the console's
LDEV number, enter the SHOWME command from other terminals until
the console is located.
To log on to the console
Usually, the reason for logging on to the console is to perform
operations that require the special console commands. For this reason,
you must log on to the special MANAGER.SYS account. You can log on as
MANAGER.SYS, which has SM capability, or you can log on as OPERATOR.SYS,
which has OP capability. OP capability is usually sufficient for
monitoring the console. This is also the logon identity into which the
Series 9X8LX systems boots; that is, if you have just started the
computer, you may already be in OPERATOR.SYS at the console.
1. To log on to the console
* To log on to the console from the logon prompt
MPE/iX:HELLO MANAGER.SYS Return
* To log on to the console from the system prompt
:HELLO MANAGER.SYS Return
2. You are prompted for any account and user passwords that have been
set up.
3. At the system prompt, you can perform the tasks as needed. If
there is no system prompt, press Return.
Remember that, unlike other terminals, this terminal is the system
console and should not be turned off.
To create a welcome message
A welcome message is a convenient way to transmit information of general
interest to all users of the system. To create a welcome message, use
the WELCOME command. This command can be issued only at the system
console. (To create a Welcome message using any terminal, refer to
chapter 9.)
To create a welcome message, do the following:
1. Type WELCOME at the system prompt:
:WELCOME Return
2. At the # prompt, begin creating your message. To end your
message, press Return at the # prompt. Enter as many lines as you
wish; however, the length of each line cannot exceed 72
characters.
_____________________________________________________________________
| |
| |
| #WELCOME TO THE HP 3000. THE SYSTEM Return |
| |
| #WILL BE BACKED UP ON MONDAY NIGHT AT 17:00. Return |
| |
| #THERE WILL BE A POWER SHUTDOWN ON SATURDAY, MARCH 9. Return |
| |
| # Return |
| |
_____________________________________________________________________
3. To check your welcome message, use the SHOWME command at the
system prompt.
To erase a welcome message
To delete an old welcome message, do the following:
1. Type WELCOME Return.
2. At the # prompt, press Return.
To send an urgent message to all users
Use the WARN command to send urgent messages to users of the system.
This command can be issued only from the system console.
:WARN @;message up to 67 characters. Return
The message text of the WARN command should contain no more than 67
characters. Type one continuous line without pressing the Return key.
When you are finished writing the warning message, press Return. This
action terminates the message text and sends the warning message to all
users logged on to the system.
WARN @; THE SYSTEM WILL SHUTDOWN IN 5 MINUTES. LOG OFF NOW. Return
To control the number of jobs
You can set a limit on the number of jobs that the computer processes by
using the LIMIT and JOBFENCE commands.
With job and session limits.
The job and session limits set the number of jobs and sessions that can
process at the same time. If the job limit is set at 10, only the first
10 jobs are allowed to begin processing. Subsequent jobs wait in the
input queue until one job ends so that another can begin. The session
limit controls the number of sessions that can be opened at one time.
* To set the job limit to 10 and the session limit to 25, enter the
limit for jobs and then sessions in the LIMIT command:
:LIMIT 10,25 Return
* To set only the job limit to 10, enter:
:LIMIT 10 Return
* To set only the session limit to 25, use a comma as a place holder
for the job limit, followed by the session limit number:
:LIMIT ,25 Return
With the jobfence.
The number of jobs processing on the system can also be controlled by the
job priority. This priority level is called the jobfence. To execute, a
job's priority must be the same as or greater than the jobfence. The
jobfence is a number from 0 to 14 that can be raised and lowered to
increase or reduce the priority of jobs permitted to run. If the
jobfence is high, a job needs a high priority to run on the system at
this time. Lowering the jobfence allows jobs with lower priorities to
run on the system too. Usually the jobfence is set at a priority of 5.
:JOBFENCE 5 Return
To display outstanding messages
To display outstanding messages, known as reply requests, at the console,
use the RECALL command.
:RECALL Return
The following example shows the display of several types of console
messages.
_________________________________________________________________
| |
| |
| THE FOLLOWING REPLIES ARE PENDING: |
| ?13:57/#S25/43/LDEV# FOR "T" ON TAPE (NUM)? |
| ?14:04/#J36/44/FORMS; PLEASE MOUNT PAYROLL CHECKS |
| ?14:04/#77/45/#SP12/LDEV# for #J36; OUTFILE ON LP (NUM)? |
| |
_________________________________________________________________
Console messages provide the following information:
* The time the request was made, using a 24 hour clock (13:57 and
14:04).
* The requestor's job (#Jnn) and session (#Snn) numbers.
* The process identification number, or PIN, following the second
slash / symbol. In the above example, 43, 44, and 45 represent
PIN. This number identifies who should receive the reply.
If there are no pending messages sent to the console, the following
message appears on the screen:
NO REPLIES PENDING (CIWARN 3020)
To respond to a tape reply requests.
1. Locate the proper cassette tape.
2. Determine whether the tape should be a read and write tape or a
read-only tape.
3. Load the tape into the DDS tape drive.
4. Use the REPLY command. Enter the PIN number that appeared in the
request. Also enter the LDEV for the DDS tape drive.
:REPLY 43,7 Return
To respond to a special forms request.
At times, it may be necessary to load special forms (such as mailers,
checks, or labels) on the printer. The job is suspended until someone
responds to the message on the console.
1. Select a printer and mount the correct form.
2. Use the REPLY command to respond to the message requesting the
printer's LDEV number. Enter the PIN and the LDEV number of the
appropriate printer.
:REPLY 44,6 Return
The printer runs briefly to print a test pattern. It is then
suspended again with another request.
?14:20/#77/44/LDEV #6 FORMS ALIGNED OK (Y/N)?
3. Look at the test pattern that has printed, and verify the
alignment of the printing with lines or boxes on the form.
(Often, program documentation supplies a sample of how the test
pattern should look if it is aligned properly. Compare the sample
with the test pattern.) Fix the alignment of the form, if
necessary.
a. If the forms were already aligned accurately and you did
not make any adjustment, reply YES.
:REPLY 44,YES Return
b. If you adjusted the forms, reply NO to the prompt.
:REPLY 44,NO Return
4. A negative reply prints another test pattern and prompts you to
verify the alignment again. Continue this sequence to test the
printing until the form is aligned properly and you can reply YES.
To respond to any user message.
A user can send messages to the console, using the TELLOP command. The
following is an example of how a user's message is displayed on the
console screen:
14:15/#S27/46/FROM PAT.PAYROLL/HOW SOON IS SYSTEM SHUTDOWN?
The TELLOP command supplies the following information to the console
screen:
* the time the message was sent (14:15)
* the session number from which the message was sent (#S27)
* the LDEV, logical device number, of the sender's terminal (46)
* the sender's logon identity (PAT.PAYROLL)
* the message text
To reply to a TELLOP message, use the TELL command. The sender of this
message is identified by the session number or logon identity, in this
example, #S27.
:TELL #S27;SHUTDOWN IS AT 7:30 Return
