Nonsynchronized interval accounting

When interval accounting is not synchronized, SMF generates type 30 interval records for a work unit at the end of a recording interval based on the start time of a the work unit. Each interval record contains data for the resources used during the recording interval.

Example: Assume a recording interval of 30 minutes. If a job step starts at 9:10 AM, and runs for two hours and six minutes, then SMF generates a type 30 record at the following times:

  9:10 AM    (job step start time)
  9:40 AM    (30 minute interval ends)
 10:10 AM    (30 minute interval ends)
 10:40 AM    (30 minute interval ends)
 11:10 AM    (30 minute interval ends)
 11:16 AM    (job step completion time)
