You can view and edit an application design, for example, if you need to add another application server or open or reconfigure a service.
1 On the Applications page, click the application instance name. The Canvas tab is displayed.. The application design tab is displayed.
2 Edit the application design as required.
3 Click Publish to publish the application for the first time or click Update to apply the changes to a published application, as applicable.
Note: The update process does not republish the entire application, only the relevant changes. In some cases, a published VM will be rebooted as part of the process.
