Developing EJB 2.x enterprise beans

  • 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.
