In other words W access gives you W, R and E access but not D.K

  • ACL: Each job can have an Access Control List associated with it. D An ACL is a list of identifiers and what access each one of thusEidentifiers can obtain. The rules for ACL formating are the standard EVMS ones. Please refer to the VMS documentation for more information.E
  • FLAGS: Only one general job flag exists at this time. A flagBvalue of NOHISTORY indicates that no history information is to be accumulated for this job.F
  • STATUS: The STATUS field is an output field and indicates the:last completion status code that was generated by the job.@
  • JOB_TAG: The JOB_TAG field is the initial value that is?given the SET_TAG whenever this job is used to start a job set.F
  • PRE_COM_FILE: The PRE_COM_FILE is a command procedure that isCexecuted first before any other DCL commands associated with a job.H
  • POST_COM_FILE: The POST_COM_FILE is a command procedure that is=executed last after all DCL commands associated with the job.H
  • STARTUP_WINDOW: The STARTUP_WINDOW is used to control how jobs F that are in the B (waiting until start time) scheduling queue are I processed when the system is booted. In a cluster this would be when L all nodes go down and come up. When the system comes up a check is made K to see if any jobs in the B queue should have already been started. If J so and that start time is no more then the STARTUP_WINDOW in the past J the job is initiated. The main purpose is to prevent extra job starts 0 if the system has been down for a long time.L
  • EXECUTE_WINDOW: The EXECUTE_WINDOW is maximum time that is allowed I for a job to go from the E (waiting for prerequisites) to the M (job H completed) scheduling queue. If this limit is exceeded any initiate J jobs are not activated. If a job is already in an execution queue the L batch job is allowed to terminate. The main purpose is to prevent a run K away catch up mode from taking place if the system comes back up after L being down for a long time. This condition is checked in the scheduling  queues H, I, J and M.

  • RESCHEDULING OPTIONS: Jobs that have time based starts can be I rescheduled via one of three methods. The various methods are detailed  below:
      G
    1. INTERVAL Rescheduling: Interval rescheduling uses the current H start time and just adds in the interval to determine what the next  start time should be.J
    2. MARKED CALENDAR Rescheduling: Marked calendar rescheduling looks J for a specified mark (a letter A through Z) on the indicated calendar 7 and then runs the job at the indicated time of day.I
    3. NAMED DAY Rescheduling: Named day rescheduling selects the next J run date by the name of the day (MONDAY, TUESDAY, etc.) and then runs ) the job at the indicated time of day.B
    4. CALENDAR: This field indicates what calendar to use when I determining the next start time. For example, what days are holidays 9 and weekends is determined by examining the calendar.E
    5. NONE: This option clears out all automatic job rescheduling.
