JOBFENCE 

The JOBFENCE command defines the minimum input priority that a job or a
session must have in order to execute.

Syntax 

JOBFENCE priorityfence 

Parameters 

priorityfence         The number 0 allows a job or session to log on with
                      any INPRI value.  The number 14 prevents all jobs
                      and sessions from logging on regardless of their
                      INPRI value.  The use of HIPRI as well as the job
                      and session limits affects the ability of a job or
                      session to log on.

                      The system does not process jobs or sessions with
                      an input priority less than or equal to the
                      priorityfence until you raise their input priority
                      with the ALTJOB command or lower the jobfence.

Operation Notes 

   *   Usage 

       You can enter this command from a session, a job, a program, or in
       break mode.  Pressing Break does not affect this command.

       You must enter this command from the console; however, you can
       enter this command from your terminal if your system administrator
       has used the ALLOW command, which permits you to enter this
       command.

   *   Overriding the jobfence 

       If you have SM or OP capability, you can override the jobfence
       setting by logging on with the HIPRI parameter of the JOB or HELLO
       commands.  Alternatively, you can log on with an input priority
       greater than the jobfence, as indicated by the SHOWJOB command.

Examples 

   *   To defer all non-HIPRI jobs and sessions and then allow waiting
       jobs to log on, do the following:

          1.  Set the jobfence to 14:

                   :JOBFENCE 14 
                   16:18/#J7/34/DEFERRED JOB INTRODUCED ON LDEV #10
                   16:18/#J8/35/DEFERRED JOB INTRODUCED ON LDEV #10

          2.  Enter the SHOWJOB command to display the effect of the new
              jobfence:

                   :SHOWJOB 

                   JOBNUM  STATE  IPRI  JIN   JLIST  INTRODUCED  JOB NAME

                   #S26    EXEC          20   20     THU  4:17P  OPERATOR.SYS
                   #J7     WAIT   D 8    10S  12     THU  4:18P  JOB1,FIELD.SUPT
                   #J8     WAIT   D 8    10S  12     THU  4:18P  JOB2,FIELD.SUPT

                   3 JOBS:
                      0 INTRO
                      2 WAIT; INCL 2 DEFERRED
                      1 EXEC; INCL 1 SESSIONS
                      0 SUSP

                   JOBFENCE= 14; JLIMIT= 5; SLIMIT=16

          3.  Reset the jobfence to 6 to allow waiting jobs to log on:

                   :JOBFENCE 6 

                   16:21/#J7/34/LOGON FOR: JOB1,FIELD.SUPT ON LDEV #10
                   16:21/#J8/35/LOGON FOR: JOB2,FIELD.SUPT ON LDEV #10
