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.
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. Use the two-character reset commands to reset the system. At the CM> prompt, enter: 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.
|
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)?>
|
For the above message, enter: 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: The system responds:
Booting.

Enter the start command at the ISL> prompt: 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)?
|
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: After you have entered the current month, day, and year, the system replies: After you enter the time, the system asks you to verify that the date and time are correct. Enter: 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: If the CTRL B prompt (CM>) is on the screen, enter: Then press Return again. This takes you out of Control-B mode. If the CTRL A prompt (=) is on your screen, press Return a couple of times. 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:
|
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. Verify your logon by entering: The screen displays:
USER: #S18,YOUR.ACCOUNT,PUB (NOT IN BREAK)

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.
To check and reset the job and session limit | |
To check and reset the job and session limit, enter: If you know what the values should be, set them now, using the LIMIT command. Enter: 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. To check and reset the spooler outfence, enter: 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: To reset an individual outfence, enter:
