Extended Control Procedures

The following procedures are defined for the system#container component type:

• default install block – Installs only those child components that have installMode=“NESTED” set.

• markOnly install block – Calls the markOnly install block of all the nested child components, then marks this component as installed.

• default uninstall block – Uninstalls only those child components that have installMode=“NESTED” set.

• markOnly uninstall block – Calls the markOnly uninstall block of all the nested child components, then marks this component as uninstalled.

• default snapshot block – Captures a snapshot of all child components if createSnapshot is set to true. Only child components that have installMode=“NESTED” set are installed. By default, createSnapshot is set to false.

Snapshots are not always enabled. If the component is deployed as a nested component of another component, it should be deployed with createSnapshot=“false” because the container component will capture a snapshot of this component after all of its contained components have been deployed. If the component is being deployed as a top-level component, you can enable snapshots by setting createSnapshot=“true”.

Snapshots are not captured when a component is contained in a container component. The deployment of the other contained components after this component might affect the installed state of this component. Thus, the snapshot is captured after the top-level installations have completed.
