Deferred Create for container managed persistence

Note: This page applies to WAS Version 5.0.2 and later only.

The specification for Enterprise Java Beans (EJB) 2.x states that for Container Managed Persistence (CMP) during the ejbCreate, the container can create the representation of the entity in the database immediately, or defer it to a later time.

WAS Version 5.0.2 enables you to take advantage of this specification. You can turn this option on from the EJB CMP side. When you choose this option, the run time defers ejbCreate (or the equivalent database persistence request) until it is needed. This can be at the end of the transaction, or when a flush is needed for finders related to this EJB type. By doing this you can reduce two round trips for the newly created entity (insert and update) to one (insert).
