About the Security Models for SAI for Oracle Fusion Middleware

The two security models available for SAI for Oracle Fusion Middleware are:

• Deployment Descriptor Only (DD Only)
• Custom Roles and Policies

You choose a security model when you deploy each Web application or Enterprise Java Bean (EJB), and your choice is immutable for the lifetime of the deployment. If you want to use a different model, then you must delete and redeploy the Web application or EJB. For more information about the security models, see Oracle® Fusion Middleware Securing Resources Using Roles and Policies for Oracle WebLogic Server available in the Oracle Fusion Middleware 11g Release 1 Documentation Library.
