You can use Runtime Manager to view and control the Scheduler components within the flows in your
deployed applications. Use the **Schedulers** tab in the navigation menu to enable or disable
Scheduler elements, change the frequency, or run the scheduled job immediately, all without changing
the running application.

From the **Schedulers** tab, you can:

- Enable or disable the Scheduler

- Change the frequency

- Specify when to start running the Scheduler

- Specify the timezone for a cron Scheduler

> [!NOTE] You can’t set a timezone for a scheduler running on CloudHub or Government Cloud.

Runtime Manager lists the name of each Scheduler component as `polling://{flow_name}`.

## Use Cases

Schedule management is useful in the following contexts:

- You want to change the schedulers in your application at runtime without redeploying.

- You want to disable a scheduled job while one of the applications you are connecting to is
  undergoing maintenance.

- You want runtime visibility into the schedulers in your application.

## Considerations and Limitations

When using the **Schedulers** tab, consider the following:

- If a scheduled job is not triggered because the application is not running, Runtime Manager
  triggers the job as soon as the application restarts.

- The scheduler reads the job configuration every time it runs.

  To apply your changes immediately, run your jobs manually after updating the schedule.

## View and Manage Application Schedulers in Runtime Manager

To use the scheduling feature in Runtime Manager, deploy an application that includes one or more
Scheduler elements:

![Scheduler component in the Anypoint Studio canvas](/mulesoft/current/en-us/runtime-manager/_images/hybrid-scheduler-studio.png)

Figure 1. The arrow shows the **Scheduler** component in the Anypoint Studio canvas.

After deploying the app, view and manage the Scheduler elements in Runtime Manager:

1.  Click **Applications** in the left pane, click the app name, and then click **Schedulers**:

    Figure 2. The screenshot shows (**1**) the **Schedulers** option and (**2**) the checkbox on the
    **Schedulers** page.

    The **Name** column shows the name of the flow that contains the Scheduler element.

    Runtime Manager lists the Scheduler elements in the order that they appear in your application:

    Figure 3. The screenshot shows (**1**) the checkbox, (**2**) the **Disable** button, and (**3**)
    the schedule in the details pane.

2.  Enable one or more schedulers by selecting checkboxes and clicking **Enable**.

3.  Update a cron Scheduler by selecting a single checkbox and updating the schedule configuration
    in the details pane:

    ![Schedule configuration in the details pane](/mulesoft/current/en-us/runtime-manager/_images/hybrid-scheduler-cron.png)

    Figure 4. The arrow shows the cron schedule configuration in the details pane.

4.  Update a fixed-frequency Scheduler by selecting a single checkbox and updating the schedule
    configuration in the details pane:

    ![Schedule configuration in the details pane](/mulesoft/current/en-us/runtime-manager/_images/hybrid-scheduler-fixed-frequency.png)

    Figure 5. The arrow shows the fixed-frequency schedule configuration in the details pane.

5.  Disable one or more schedulers by selecting checkboxes and clicking **Disable**.

6.  Click **Update** to save changed settings.
