An update process to scale in a deployment might fail sometimes. A cleanup to retry deprovisioning of the
new virtual machines is required following the scale in update failure. Deprovisioning the newly created
virtual machines manually is a tedious task and is difficult for external services users. To avoid the manual
effort, automatic deletion of virtual machines is considered. Set the following flag to True, to retry the
cleanup of virtual machines if deletion fails in the first attempt:
n
UPDATE_RETRY_VM_DEPROVISIONING_AFTER_FAILURE_FLAG
Set the following flag to True to retry deletion of virtual machines with a delay in milliseconds:
n
UPDATE_RETRY_VM_DEPROVISIONING_AFTER_FAILURE_DELAY_INTERVAL
Prerequisites
n
Log in to Application Services as an application publisher and deployer.
n
Familiarize yourself with the basic concepts of defining and configuring component properties and
actions. See Chapter 12 Developing Application Services Components.
n
The deployed application must include at least one clustered node. See Specify a Node as a Cluster.
n
If you plan to add a custom task, verify that at least one custom task is created in the Application
Services library. See Add a Custom Task to the Library.
n
Verify that the initial deployment is successfully deployed to a cloud environment.
You cannot scale clustered nodes from a failed deployment or after a failed scale operation.
n
Contact your cloud administrator to get information about the deployment environment storage space
limit.
