Usage

• Go to Scheduled job listing -> Edit any job -> select checkbox Advanced Job Scheduling, then additional details get displayed
• Set your job frequency either using Basic Setting or the Advanced Setting.
• Set Run Frequency Time Margin for at least 5 min (default value is 5)

  • We are using the Linux Cron tab-like format to run the cron job at a specific time, but this is not an actual crontab; we are totally relying on CiviCRM Job. CiviCRM jobs are executed by crontab-like features.
  • We may run a CiviCRM job every 5 or 10 minutes. But this will not be executed at the scheduled time. So we have to give some relaxation using this margin setting.
  • Provide a margin in the number of minutes based on the crontab frequency of the main civicrm job. If empty, we will use 5 minutes as the default margin.

• Set a scheduled start and end date.

  • The scheduled job only gets executed on the specified date.

• Set the active time of each scheduled job.

  • We can run scheduled jobs every 30 minutes but only execute them in business hours from 9 a.m. to 5 p.m., or run them after business hours from 8 p.m. to the next morning at 7 a.m.
