The START NORECOVERY method of starting the system does not retain scheduled jobs. Use the START NORECOVERY command:

  • When the system configuration has changed.

  • If a START RECOVERY failed.

To start the system without recovery

Use the START NORECOVERY option:

  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. Enter:

       RS Return
    

    The computer responds:

    Type Y to confirm your intention to restart system (Y/N):
    

    Enter:

       Y Return
    

    The computer responds with messages similar to the following:

    SPU hardware was successfully reset.
    
    
    
    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 NORECOVERY, 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. Since you are doing a START NORECOVERY, boot the system from the primary path disk. Press:

       Y Return
    

    The system responds:

    Interact with IPL (Y or N)?>
    
  5. For the above message, enter:

       Y Return
    

    The system responds:

    Booting.

    ISL>
    
  6. Enter the start command at the ISL> prompt:

       START NORECOVERY  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, 1990,  5:00:00 PM (Y/N)?
    
  7. 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.

  8. 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)?
    
  9. After you enter the time, the system asks you to verify that the date and time are correct. Press:

       Y Return
    

    The system seems idle for a couple of minutes before it continues booting.

To prepare the system for normal activity

If your operator session was not automatically started, you have to log on to the console.

  • At the system prompt (MPE XL), enter:

       HELLO OPERATOR.SYS;HIPRI Return
    

    Adding HIPRI allows you to start a session regardless of the value of the session limits or jobfence. If you do not see one of the following prompts or your application prompt, you need to reset and start the computer:

       MPE XL:
    
       :
    
       ENTER GROUP PASSWORD:
    
       ENTER ACCOUNT PASSWORD:
    
       ENTER USER PASSWORD:
    

    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:

       SHOWME Return
    

    The screen displays:

    USER: #S18,YOUR.ACCOUNT,PUB      (NOT IN BREAK)
    
    RELEASE: X.40.12   MPE/iX  HP31900 B.19.22   USER VERSION: X.40.12
    
    CURRENT: TUE, JAN 22, 1991,  3:00 PM
    
    LOGON:   TUE, JAN 22, 1991,  2:59 PM
    
    CPU SECONDS: 0         CONNECT MINUTES: 1
    
    $STDIN LDEV: 20         $STDLIST LDEV: 20
    

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 limits, 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. 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
