Self Help Online Studio - Scheduled Task Management

Last modified on 2022/08/08 16:20

You manage scheduled tasks, i.e. scheduled, delayed or immediate execution tasks, in Self Help using the cron/ task scheduler*./*

  • cron is used to manage all extraction, metadata import and user import tasks.
  • The program enables you to run tasks automatically according to specific dates and times.
  • You can specify the conditions for running these tasks by defining triggers. You define the trigger as a cron expression.


  • You cannot modify the type of task.
  • Executed tasks cannot be modified.


  • The immediate execution of a task may generate performance bottlenecks on the Self Help server.

Best Practice

  • Use CronMaker to specify the trigger conditions for running tasks easily using cron expressions.
