For EJB 2.x CMP entity beans, we can use the partial update feature to specify how to update the persistent attributes of the CMP bean to the database. This feature is provided as a bean-level persistence option, called PartialOperation, in the access intent policy configured for the bean.
See the topic Partial operation for container managed persistence in the assembly tool information center to learn how to complete this task with the assembly tool.
