In fact, if we want to audit any DML operation on objects and also need to audit additional cases that violate specific conditions on sensitive columns, then we must rely on fine-grain auditing.

In this recipe we will define two fine-grained audit policies. One will be defined on Emp _ Details_View and will perform general auditing, and one the EMPLOYEES table that are using an access condition on the salary and commission_pct columns. Both objects belong to the HR schema.

Getting ready

How to do it...

We will apply a fine-grained audit on EMP_DETAILS_VIEW.

  1. As the user system define a policy name empd_vw_fga_policy on emp_details_view as follows:

    SQL> exec dbms_fga.add_policy(object_schema=>'HR',object_name=>'EMP_DETAILS_VIEW...
