G How the Unified Auditing Migration Affects Individual Audit Features

Most of the pre-Oracle Database 12c release 1 (12.1) auditing features can be used before a unified auditing migration.

Table G-1 describes how the pre-Oracle Database 12c audit features change in the migration.

DBMS_FGA.ADD_POLICY Procedure Parameters	-	-
`audit_trail`	Yes, and is used as in previous releases	Yes, but when unified auditing is enabled, you can omit this parameter because all records will be written to the unified audit trail.

^Footnote 1

These data dictionary views will continue to show audit data from audit records that are still in the SYS.AUD$ and SYS.FGA_LOG$ system tables. Unified audit trail records are shown only in the unified audit trail-specific views. You must be granted the AUDIT_ADMIN or AUDIT_VIEWER role to query any views that are not prefaced with USER_.
