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.

Notes

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

Caution

• 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.

Menu access
