Chapter 8 Creating J2EE Applications for BEA WebLogic

Restrictions and Warnings for db-is-shared

Setting db-is-shared to "false" overrides WebLogic Server's default ejbLoad() behavior, regardless of whether the EJB's underlying data is updated by one WebLogic Server instance or multiple clients. If you incorrectly set db-is-shared to "false" and multiple clients (database clients, other WebLogic Server instances, and so forth) update the bean data, you run the risk of losing data integrity.

Also, due to caching limitations, you cannot set db-is-shared to "false" in a WebLogic Server cluster.
