Synchronized interval accounting

When interval accounting is synchronized, SMF generates interval records for a work unit based on the end of the SMF global recording interval, rather than the start time of a job. Interval synchronization is particularly useful when you want to compare interval records generated by SMF, RMF™, and other requestors.

Example: Assume the SMF global recording interval has a length of 30 minutes and is synchronized with 15 minutes past the hour. If a job 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 start time)
  9:15 AM    (SMF global recording interval ends)
  9:45 AM    (SMF global recording interval ends)
 10:15 AM    (SMF global recording interval ends)
 10:45 AM    (SMF global recording interval ends)
 11:15 AM    (SMF global recording interval ends)
 11:16 AM    (job completion time)
