By scheduling activities, organizations can give critical tasks higher priority and reduce resource contention. Jobs that affect the entire encyclopedia, such as image copy and reorganization, should be scheduled to run at a consistent time that is communicated to all encyclopedia users. Users should understand that the encyclopedia is unavailable during this time and that all encyclopedia jobs must finish before the scheduled start time.
Schedule encyclopedia jobs that you believe may cause contention with other encyclopedia activity, such as large model copies, deletes, and migrates, during a period when other ongoing activity is curtailed. These time periods are best scheduled during non-peak hours and must be communicated and agreed upon by all encyclopedia users. All users should have access to the schedule.
For example, suppose that a user needs to copy a large model. The user knows from experience that this copy may cause DB2 contention because of the amount of inserts performed. The encyclopedia administrators could set up time periods, such as on Tuesday and Thursday evenings starting at 11:00 pm, for this type of activity. The jobs could be run in batch mode and submitted using the same jobname (single streaming the processing). The user schedules the copy to run during this time period. This increases the likelihood of having the job complete and eliminates the chance of other jobs failing.
