Performing System Operation Tasks
Starting the System under Normal Conditions
There are five ways to start the operating system:
* START RECOVERY starts the system and retains scheduled jobs. Use
this method after a normal scheduled system shutdown, system hang
or failure, or when you need to save scheduled jobs.
* START NORECOVERY starts the system but does not retain scheduled
jobs. Use this method after a change in system configuration or
if START RECOVERY fails.
The last three startup options are your system manager's responsibility:
* UPDATE NOCONFIG replaces the operating system stored on disk with
a "clean" copy from tape. The system retains and uses the
configuration files stored on disk. Update the computer at the
recommendation of your system manager, who may also supervise the
process.
* UPDATE CONFIG replaces the operating system stored on disk with a
copy from tape. In this case, the system uses the configuration
contained on the tape. Update the computer at the recommendation
of your system manager, who may also supervise the process.
* INSTALL replaces the operating system, subsystem files, and
destroys all files on the system volume set. The system volume
set files can be restored from tape. An install may require that
you reconfigure the system. This is a last resort if all other
startup options fail.
To start the system under normal conditions
Use the START RECOVERY option:
* After a normal scheduled system shutdown.
* After a system hang, or system failure.
* Anytime you need to preserve scheduled jobs.
1. Press the Return key on the console.
Look for the Control-B prompt (CM>). If you do not see it,
activate control mode by pressing the CTRL and B keys.
2. Use the two-character reset commands to reset the system. At the
CM> prompt, enter:
TC Return
A soft reset (TC) preserves the current processor state, performs
a nondisruptive memory test, and terminates I/O operations. A
hard (RS) reset is disruptive. It initiates the processor
self-test that resets memory and terminates all I/O operations.
The computer responds with messages similar to the following:
________________________________________________________________________
| |
| |
| Processor Dependent Code (PDC) revision 2.1 |
| |
| Console Path = 2/4.1.0.0.0.0.0 |
| Primary boot path = 2/4.0.0.0.0.0.0 |
| Alternate boot path = 6/4.3.0.0.0.0.0 |
| |
| 32 MB of memory configured and tested. |
| |
________________________________________________________________________
If autoboot is enabled, the system attempts to autoboot and issues
a message:
________________________________________________________________________
| |
| |
| Autoboot from primary path enabled. |
| |
| To override, press any key within 10 seconds. |
| |
________________________________________________________________________
3. If you are sure that the autoexecute file contains commands and
options that boot the system START RECOVERY, then use it.
Otherwise, override it.
If autoboot has been disabled, the system asks for boot path
information:
________________________________________________________________________
| |
| |
| Boot from primary boot path (Y or N)?> |
| |
________________________________________________________________________
4. For the above message, enter:
Y Return
Note that depending on your system you may not need to press
Return after entering Y or N.
The system responds:
________________________________________________________________________
| |
| |
| Interact with IPL (Y or N)?> |
| |
________________________________________________________________________
For the previous message, enter:
Y Return
The system responds:
________________________________________________________________________
| |
| |
| Booting. |
| |

| ISL Revision A.00.00 June 6th, 1988 |
| |
| ISL> |
| |
________________________________________________________________________
5. Enter the start command at the ISL> prompt:
START RECOVERY Return
After a minute or so, the system prompts you for the correct date
and time:
________________________________________________________________________
| |
| |
| MPE XL launch facility |
| Initialize_genesis - Version : <<870204.1552>> |
| MON, JAN 30, 1991, 5:00:00 PM (Y/N)? |
| |
________________________________________________________________________
6. If the date and time are correct, you can either press Y Return or
not take any action. After waiting 10 seconds for input, the
system assumes that the date and time are correct and continues
booting.
If the time and date are not correct, press N Return.
The system responds:
________________________________________________________________________
| |
| |
| DATE (M/D/Y)? |
| |
________________________________________________________________________
After you have entered the current month, day, and year, the
system replies:
________________________________________________________________________
| |
| |
| TIME (H:M:S)? |
| |
________________________________________________________________________
7. After you enter the time, the system asks you to verify that the
date and time are correct. Enter:
Y Return
The system seems idle for a couple of minutes before it continues
booting.
To verify that the system has been started
To verify that the system has been started:
1. If the CTRL B prompt (CM>) is on the screen, enter:
CO Return
Then press Return again.
This takes you out of Control-B mode.
2. If the CTRL A prompt (=) is on your screen, press Return a couple
of times.
3. If you do not see one of the following prompts or your application
prompt, you need to go to the "Problem Solving" section, chapter
11, of this document:
MPE XL:
:
ENTER GROUP PASSWORD:
ENTER ACCOUNT PASSWORD:
ENTER USER PASSWORD:
4. If you see a system prompt (MPE XL:), enter:
HELLO OPERATOR.SYS Return
The computer prompts you for any passwords, then displays logon
information. You will see the colon prompt on the left side of
the screen.
5. Verify your logon by entering:
SHOWME Return
The screen displays:
________________________________________________________________________

To prepare the system for normal activity
To conclude the startup, you must check, and possibly reset, the
following four things:
* The job and session limits.
* The jobfence.
* The outfence.
* The streams device.
To check and reset the job and session limit
1. To check and reset the job and session limit, enter:
SHOWJOB STATUS
2. If you know what the values should be, set them now, using the
LIMIT command. Enter:
LIMIT nn,yy
The nn and yy are the job and session limits respectively.
If you are not sure what the limits should be, check with your
system manager. If your system manager is not available, use the
following formula as a guideline:
SLIMIT = the number of terminals connected to your computer.
JLIMIT = approximately one-fifth of the session limit.
3. To check and reset the spooler outfence, enter:
SHOWOUT STATUS
4. If your system-wide outfence is equal to a number other than 1 or
14, then it has been set for you (by the SYSSTART.PUB.SYS file)
during the startup procedure. If it is equal to 1 or 14, check
with your system manager for the correct outfence. For example,
if the correct outfence is 6, enter:
OUTFENCE 6
5. To reset an individual outfence, enter:
OUTFENCE 6;DEV=nn
To set the streams device
To allow users to stream jobs, enter:
STREAMS 10
