Security policies are stored differently in Oracle Database 12c. You may need to carry out actions before and after upgrades.
In Oracle Database 12c, Oracle OLAP uses Oracle Real Application Security (ORAS) to store OLAP data security policies instead of Extensible Data Security (XDS), which it used in Oracle Database 11g releases.
When you upgrade Oracle Database from release 11g to release 12c, any XDS data security policies are automatically converted to ORAS.
Data security roles defined in a release 11g Oracle Database instance are not automatically converted to ORAS. Before you upgrade an 11g database to Oracle Database 12c, you must delete any data security roles that are defined in the 11g database. After the upgrade, you may use Analytic Workspace Manager 12c to define the data security roles again.
If you upgrade an 11g database to Oracle Database 12c without deleting the 11g data security roles, then any data security policies that include a data security role are invalid in the Oracle Database 12c database.
