Checking and updating the EBA asset version used by a business-level application

When you change the versions of bundles that an enterprise bundle archive (EBA) asset uses, the asset can get out of synchronization with the associated business-level application. To check that your business-level application is running an up-to-date version of the EBA asset, you check the status of the associated EBA composition unit. If a new version of the EBA asset is available, and all bundle downloads for the asset are complete, restart the business-level application to bring the EBA composition unit up-to-date and run the newer configuration.

About this task

When an EBA asset is updated, the update does not immediately affect the running business-level application that contains the associated EBA composition unit. When the business-level application is next restarted, the deployed content of the EBA composition unit is updated to reflect the updated configuration of the underlying asset. Because it can take time to download new bundle versions, you must wait until the bundle downloads for the asset are complete before you restart the business-level application. If you restart a business-level application before the bundle downloads are complete, the business-level application uses the previous configuration.

You associate an EBA asset with a particular business-level application through a composition unit. There are three distinct statuses for an EBA composition unit in a business-level application:
Up-to-date
The composition unit is running the latest configuration of the backing asset.
Update in progress
The backing asset is currently undergoing a bundle version update; a restart of the business-level application will not change the current running configuration of the asset in this EBA composition unit.
New version available
The backing asset is available at a newer configuration to that which is currently running in this composition unit. A restart of the business-level application will bring the composition unit up-to-date and run the newer configuration.

You can check whether the EBA composition unit is up to date by using the administrative console, or by using the viewCompUnit command.
