Under the Hood of the OTM Database Security Layer
Eric Rosenbloom, Oracle
This technically focused session will examine how the Oracle Virtual Private Database (VPD) feature is utilized to allow multiple Domains to coexist on the same OTM instance. You will learn about how VPD works under the hood, and the underlying mechanisms for managing domains, domain grants, external predicates, vpd contexts, users, and user roles. There will also be discussion of what makes a good domain design, as well as a discussion of how VPD impacts database performance.
