IC67905: THE LOGIC OF SETTING THE NEXT EXECUTION TIME FOR A TASK MIGHT LEAD TO LOTS OF UNWANTED RUNS OF THE TASK

APAR status

• Closed as program error.

Error description

• When there is a task in sysadmin:ph_task table which has
  tk_start_time set and tk_frequency set  to value less then 1
  day, this task might be run several hundred times between its
  last 'standard' schedule in a particular day and the midnight
  that day.
  This behavior can have several side effects:
  - in case the time between last 'standard' run and midnight is
  long enough (30-50 minutes), the task might return error -213
  repeatedly which finally leads to scheduler shutdown
  - in case the AUS Evaluator & Refresher are scheduled for the
  same day, they might meet in time (even thought they are
  scheduled to different times) sometime between 23:01 and
  midnight and produce various errors like -710 for aus_command
  table, -206 or -244 for aus_cmd_info table and like

Problem conclusion

• The problem is first fixed in 11.50.xC7. When there is a task in
  sysadmin:ph_task table which has tk_start_time set and
  tk_frequency set to a value less than 24 hours, this task will
  be run only at the expected execution times.
