My application uses WAS 7 and Oracle 11g. I'm searching for zero downtime during deployments. The deployment involves EAR deployments to WAS and DDL/DML changes to Oracle DB.
One of the team here has achieved this using EBR views (Edition based revision) layer for each table. However my application uses JPA and Hibernate. I've conducted a small PoC to create entities for Editioning Views; however it seems JPA or Hibernate does not support them.
Is there any information available about using Editioning Views with JPA or Hibernate?
