The unified audit facility serves to consolidate all audit trails into a single audit trail table, improve audit performance, secure audit data and components like RMAN and Data Pump.
The unified audit feature will address the following challenges:
· Grouping audit options into a simple audit policy
· Merging all audit trails into a single unified audit trail table
· Relying on a read-only audit trail table
· Separating audit administration duties with audit administration roles, AUDIT_ADMIN and AUDIT_VIEWER
· Ability to use System Global Area (SGA) queues for accumulating audit records, enabling auditing to be turned on with negligible overhead
