# Managing Deployed Applications

Once you have deployed applications, you can perform certain management tasks on them from the **Deployed Applications** interface of the **Deployed** section.

## **Loading and unloading applications**

If you want to temporarily make a deployed application unavailable, you simply need to unload it by selecting it in the list and pressing **Unload**. When an application is unloaded, users can no longer start it using its URL. 

If you want to make it available again, simply press **Load** to reload it.

## **Editing an existing application**

Editing an existing application allows you to go through all configuration sections again and change any options as needed. 

Double-click on the application’s name and select **Edit**.

## **Clone an existing application**

Select an application to duplicate it.

## **Updating applications**

Updating a deployed application means deploying it again, overwriting the existing version. This is equivalent to editing an existing application and keeping all the same options. 

{% hint style="info" %}
Updating applications is useful when you install a new version of JMap to make sure your deployed application uses all the latest library versions. 
{% endhint %}

You do not need to update deployed applications when the data or the project changes.

## **Permissions**

If you select a deployment in the **Deployed Applications** table, you can access the **Permissions** section. You can also access it from the application configuration interface.

**Permissions** section has two tabs: **Permissions** and **Owners**. The owners are the only ones who can manage the administrative permissions for the deployment, manage the list of owners and delete it.

A list of users and groups with permissions appears in the **Permissions** tab. Click on ![](https://2224254070-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FDUF1p2rT0hfE3QBlbbvE%2Fuploads%2F3KaDFt9YF0qzIwNBwAHo%2Fajouter.png?alt=media\&token=d3e3f51e-5214-4536-b702-4ce2653e254f) to add new users or groups.

{% hint style="info" %}
Available users and groups are configured in the JMap Server section of JMap Admin. Refer to the [Users and Groups ](https://docs-jmapserver-lima.k2geospatial.com/e/administrator/jmap-server-administrator-manual/jmap-server/security/users-and-groups)section for more information about managing users in JMap Server.
{% endhint %}

Deplyments have only administrator permissions.

## **Downloading applications**

If an application’s type is **External**, you can download that application’s .*war* file in order to deploy it on another web server.&#x20;

In the application configuration interface, press **Download**.

For more information on external applications, see [this section](https://docs-jmapserver-lima.k2geospatial.com/e/administrator/jmap-server-administrator-manual/jmap-server-applications/deployment-classical-jmap-applications/..#creating-a-new-deployment).

## **Deleting applications**

Deleting an existing deployed application deletes all files related to this application. There is no way to undelete an application (you need to redeploy it).&#x20;

{% hint style="info" %}
When deleting an application, none of your data or configurations (projects, layers, data sources, databases, etc.) are deleted nor affected in any way.
{% endhint %}
