# Scheduler
The scheduler manages time scheduling and orchestrates task execution at the specified time.
Three different modes are available:
* Manual: The task will be started manually by connected user.
* Automatic: The task will be automatically executed by the schedule, once the task is finished, the software will wait 5 minutes and restart the task after this delay. Only one execution of each task can be performed in the same time. There is no option to start twice a same task.
* Schedule: The task is executed periodically following a defined schedule.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.nodeum.io/data-mover/console/data-mover-management/policy-based-task-orchestration/scheduler.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
