7.2 Backlogged Work 7.2 Backlogged Work There will be times when schedules or jobs will not complete the day on which they were selected which means that they may be candidates for being backlogged, but first, define what a day is. In terms of your company, a day would be your normal daily business computer cycle. For example, production work starts at 16:00 and is to be completed by 08:00 the next morning. This is fairly typical which means you run autoscan at, or shortly after, 08:00 (to select schedules and jobs for the next 16:00 to 08:00 time period). Thus, in terms of Unicenter CA-Scheduler, a day is the 24-hour period that starts with the time that you run autoscan. This is termed the production day or autoscan day. Schedules and jobs that do not complete on the production day on which they were selected can be carried over to the next production day. They are then called backlogged schedules or jobs. When you define a schedule or job to the database, specify whether that schedule or job is a candidate for backlog. Normally it is. What happens if the work for a production day is not complete is next described. Job Backlog The normal situation allows schedules to be backlogged. When autoscan is initiated and it is determined that a schedule is still active (it has not finished running yet), the schedule will be backlogged. Any job in the schedule that has completed, been canceled, or purged will retain its status. If a job has been defined with BACKLOG=YES, it will be backlogged if it had not started. That is, it will be allowed to run. If a job in the backlogged schedule has been defined with BACKLOG=NO and still has a status of WAITING, it will be canceled with a status called NO BACKLOG CNCL. Once all jobs in the backlogged schedule have been completed or canceled, the schedule will be marked as complete. If the same schedule was also selected on the current production day, then it and its associated jobs will be placed on the Unicenter CA-Scheduler tracking file and processed as if it had been selected normally. If a daily schedule gets backlogged for greater than 24 hours (that is, it is backlogged by two autoscans), then when it completes, the schedule to execute on the completed day is loaded to the tracking file. For example, if Monday's schedule gets backlogged and 7-8 Unicenter CA-Scheduler User Guide
7.2 Backlogged Work completes on Wednesday, Tuesday's schedule will never be run. Schedule Backlog Requested Jobs And Schedules When BACKLOG=YES or NO is specified on a schedule definition, it acts only as a default for jobs in that schedule when BACKLOG is not specified on a job. Then it is handled as described in the previous paragraph under the caption Job Backlog. Jobs and schedules that are ON-REQUEST and are still in the inactive queue at autoscan time will be purged, regardless of their BACKLOG value. 7.2.1.1 In Summary NO BACKLOG CNCL is a status code that means the job was canceled at the end of the day because it had not yet started and it was defined as, or defaulted to, BACKLOG=NO. The jobs carrying this status have not yet started and will not be run. As soon as the schedule ends, they will be purged. When history is generated for these NO BACKLOG CNCL jobs, they will show up on the Pending Job Profile Advantage CA-Earl report for the current production day. When a schedule is backlogged and it is also to be selected for the current production day, the one being selected will not be placed onto the Unicenter CA-Scheduler tracking file until the backlogged one completes. Only one copy of a schedule at a time will be kept on the tracking file. Therefore, if for some reason a schedule occurs daily and is backlogged twice, the schedule for the middle day would never be brought in. Another example is that if a schedule runs Monday and Tuesday only, and Monday's schedule gets backlogged until Wednesday, Tuesday's schedule will never be run. This is because when Monday's schedule finishes and Tuesday's is brought in, it is evaluated for Wednesday. Since there is nothing in this schedule to run on Wednesday, it will never get started.
