You can initiate an update process for predefined sample application deployments multiple times by scaling the clusters of a node. When you scale out or scale in a clustered node of a deployed application, you can configure only the cluster size of the nodes that are modeled as clusters in the application blueprint.

You can scale the following predefined sample applications.

Nanotrader application

Clustered DotShoppingCart application

Clustered Dukes Bank 3.0.0 or 2.1.0 application version

Verify that you installed the VMware vCloud Application Director for Release Automation edition to update a deployed application.

Verify that your user account has the ROLE_DEPLOYER deployer role assigned to it.

Familiarize yourself with the basic concepts of defining and configuring component properties and actions. See Developing vCloud Application Director Components.

The deployed application must include at least one clustered node. See Specify a Node as a Cluster.

Verify that the initial deployment is successfully deployed to a cloud environment.

You cannot scale clustered nodes from a failed deployment to modify configuration.

Contact your cloud administrator to get information about the deployment environment storage space limit.
