16 Review the modified properties and actions in the update.
The dependent properties with defined update scripts are highlighted.
17 Click Update to deploy the updated application.
The update process deploys the scaled in update to the cloud.
What to do next
You can check the status of the deployment from the deployment summary page. See Using the
Deployment Summary Page.
Learn about the various processes that take place in the background when the deployed application is
updated in the cloud. See Understanding the Deployment and Update Process.
Initiate an Update Process to Modify Configurations
You can initiate an update process to modify the configurations and code of existing services in a
deployed application such as Tomcat and MYSQL, or application components such as WAR and SQL.
When you modify the configurations of a deployed application, you can configure only the application
property values.
After the initial deployment, if you modify existing application components or services or modify
components that have dependent properties, an update script must run on all of the impacted and
dependent components. You define the UPDATE and the ROLLBACK life cycle stage scripts for a service
or application component during the initial application deployment or in the update process.
For example, in the Clustered Dukes Bank App, if you modify the db_port property of the MYSQL service,
during the deployment update process the update script runs on the MYSQL service. The
Dukes_Bank_App application component on the Appserver node also runs the update script because the
db_port property is bound to the db_port property of MYSQL service.
Note You cannot modify the install, config, or start scripts during an update process. You can configure
only the update or rollback script.
You can also initiate an update process to modify the configuration and code of services or application
components from the command-line interface. See Deploying and Updating an Application Using CLI.
With REST APIs in Application Services, you can automate the modification of configurations of a
deployed application. See Using Application Services REST APIs document.
