In Oracle 12c, Now we can also audit oracle data pump backups job by creating an audit policy just like a user/schema auditing.
With the help of this feature keeping eye on your data pump backups is easy now.

Syntax:
CREATE AUDIT POLICY Data_Pump_Policy_name
ACTIONS COMPONENT=DATAPUMP [EXPORT | IMPORT | ALL];

When this policy is applied to a user, their data pump jobs will appear in the audit trail.
The following policy audits all data pump operations. The policy is applied to the SYSTEM user.

[oracle@12c ~]$ sqlplus “/ as sysdba”

SQL> CREATE AUDIT POLICY audit_dp_all_policy ACTIONS COMPONENT=DATAPUMP ALL;

Audit policy created.

 

SQL> AUDIT POLICY audit_dp_all_policy BY system;

Audit succeeded.
// Run the following data pump command to backup emp table of SYSTEM schema:

[oracle@12c test_dir]$ expdp system/manager tables=emp directory=test_dir dumpfile=emp.dmp logfile=expdp_emp.log

// Checking the audit trail shows the data pump job was audited.

// Execute following PL/SQL procedure (as sysdba) to Flush audit information to disk:

SQL> EXEC DBMS_AUDIT_MGMT.FLUSH_UNIFIED_AUDIT_TRAIL;

PL/SQL procedure successfully completed.

 

// Now issue the following query to “unified_audit_trail” dictionary view for Datapump audit information: ( as sysdba )
SQL> set linesize 200
SQL> column event_timestamp FORMAT A30
SQL> column dp_text_parameters1 FORMAT A30
SQL> column dp_boolean_parameters1 FORMAT A30
SQL>
SQL>
SQL> SELECT event_timestamp, dp_text_parameters1, dp_boolean_parameters1
FROM unified_audit_trail
WHERE audit_type = ‘Datapump’;

 

 

By above we can audit data pump in oracle 12c.
