Use the Application Console

The Application Console provides access to all application configuration parameters, including the static application manifest values and the service dependencies. You can start, stop, and restart applications, and view the activity log in the Application Console.

1. Go to the Applications page.
   The page appears after you sign in or when you click on the Applications link at the top of any page. See Access Oracle Application Container Cloud Service.
2. In the Applications list, click the desired application name.

At the top of the Application Console are the application name, the application Menu , and the application URL.

A Type: worker label in place of a URL indicates a worker application. See Preparing a Worker Application for Deployment in Developing for Oracle Application Container Cloud Service.

The application Menu displays these options:

• Open Application — Starts the application using the URL.

• View Service Metrics — Opens the Monitoring graph, which displays memory usage or memory data. See View Service Metrics for an Application.

• Start — Starts all instances of the application.

• Stop — Stops all instances of the application.

• Restart — Restarts all instances of the application.

• View Activity — Displays the activity log.

If you expand the Service Details icon next to the menu icon, the following additional information is displayed:

• Location of the application in Oracle Cloud Infrastructure Object Storage Classic

• User who created the application

• Notes about the application entered when the application was created, if any

• Date-time stamp of application creation

• Metering frequency of the application, either Hourly or Monthly

• Identity domain name of the application

The following table describes the key pages available in the Application Console. By default, the application Overview page opens when you access the Application Console.

Element	Description
Overview	Overview of the application. View and change application instances and memory information. See Explore the Application Overview Page.
Deployments	Details of the deployed application. View and change service bindings, environment variables, the application launch command, and the history of the application. See Explore the Application Deployments Page.
Administration	Application administration. Apply service and runtime updates, view and download application logs, and view and download Java Flight Recorder recordings for Java applications. See Explore the Application Administration Page.

Stop, Start, and Restart an Application

You can stop, start, and restart an application from the Service Console, the Application Console, or the REST API. This section describes using the Service and Application Consoles.

Stopping an application stops the running instances and frees up the memory. The metering of the resources also stops, which is useful for hourly subscriptions. While an application is stopped, you can’t perform any of the following actions:

• Increase or decrease allocation instances

• Manage memory allocation of instances

• Redeploy the application

• Add, edit, or remove service bindings

• Add, edit, or remove environment variables

• Generate logs and recordings

Starting an application starts all stopped instances, and the load balancer starts routing traffic. Metering of the resources also starts. An application starts by default when it’s created.

Restarting an application stops it and starts it immediately. You have two options:

• Rolling restart — Instances stop and start one at a time, so the application has no downtime.

• Concurrent restart — Instances stop and start at the same time. The application is down briefly, but the overall restart time is faster.

You have these options for all actions that require restarting an application:

• Restarting the application

• Scaling memory up or down

• Updating the application runtime

• Updating Oracle Application Container Cloud Service

• Updating the application, which includes:

  • Uploading a new archive

  • Changing the launch command

  • Changing service bindings

  • Changing environment variables

Setting rolling mode in the manifest.json file causes a rolling restart upon redeployment. See Creating Metadata Files in Developing for Oracle Application Container Cloud Service.

To stop, start, and restart an application from the Service Console:

1. Open the Services Console.
2. In the Applications table, click next to the application that you want to stop, start, or restart.
3. Select the desired menu option.
4. In the confirmation dialog box, click OK.
5. If you selected the Restart menu option, then select Rolling Restart or Concurrent Restart on the Restart Application dialog, then click Restart .

To stop, start, and restart an application from the Application Console:

1. Open the Application Console.

2. In the Applications table, click the application name.

3. In the Application Console header, click next to the application path.

4. Select the desired menu option.

5. In the confirmation dialog box, click OK.

6. If you selected the Restart menu option, then select Rolling Restart or Concurrent Restart on the Restart Application dialog box, and then click Restart.

Based on your action, an event is generated in the Activity section of the Overview page.

Delete an Application

You can delete an application using the Service Console.

1. Open the Service Console.
2. In the Applications table, click next to the application that you want to delete.
3. Click Delete.
   Caution: You can't undo the deletion of an application.

Any running instances of the deployed application are stopped. The deployed application and its configuration data are deleted.
