JOBFENCE

Operation Notes

MPE/iX does not dispatch jobs or sessions with an input priority less than or equal to the priorityfence until their input priority is raised with the ALTJOB command, or until the jobfence is lowered. System managers and system supervisors may override the jobfence setting by logging on with the HIPRI parameter of the JOB or HELLO commands. Or, they may log on with an input priority greater than the jobfence as reported by the SHOWJOB command.

Use

This command may be issued from a session, job, program, or in BREAK. Pressing Break has no effect on this command. It may be issued only from the console unless distributed to users with the ALLOW command.

Examples

To defer all non-HIPRI jobs and sessions, first set the jobfence to 14, as shown below:

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

Then 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

Finally, 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
