Partial column update feature for container managed persistence
The Container Managed Persistence (CMP) bean method ejbStore stored
all of the persistent attributes of the CMP bean to the database,
even if only a subset of persistent attribute fields were changed.
This needless performance degradation is eliminated in this release
of the product.
Setting partial update for container-managed persistent beans
For Enterprise JavaBeans (EJB)
2.x CMP entity beans, you can use the partial update feature
to specify how you want 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.
