Identity generation in Hibernate (3of3)

Hibernate may be configured to assign unique identifiers to newly created entities. This feature is easy to use and does not need any tuning in single threaded, and single node environment. On the other hand, providing efficient configuration in distributed system requires careful analysis, design, and some of development effort. This note is Hibernate extension of documents "Maximize insert throughput in Oracle RAC system", and "Identity generation in load balanced WebLogic/RAC environment".
