Audit Trail Management Data Dictionary Views

Oracle Database provides data dictionary views that list information about audit trail management settings. The following table lists these views.

View Description
DBA_AUDIT_MGMT_CLEAN_EVENTS Displays the history of purge events of the traditional (that is, non-unified) audit trails. Periodically, as a user who has been granted the AUDIT_ADMIN role, you should delete the contents of this view so that it does not grow too large. For example:
DELETE FROM DBA_AUDIT_MGMT_CLEAN_EVENTS;
This view applies to read-write databases only. For read-only databases, a history of purge events is in the alert log.
For unified auditing, you can find a history of purged events by querying the UNIFIED_AUDIT_TRAIL data dictionary view, using the following criteria: OBJECT_NAME is DBMS_AUDIT_MGMT, OBJECT_SCHEMA is SYS, and SQL_TEXT is set to LIKE %DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL%.
DBA_AUDIT_MGMT_CLEANUP_JOBS Displays the currently configured audit trail purge jobs
DBA_AUDIT_MGMT_CONFIG_PARAMS Displays the currently configured audit trail properties that are used by the DBMS_AUDIT_MGMT PL/SQL package
DBA_AUDIT_MGMT_LAST_ARCH_TS Displays the last archive timestamps that have set for audit trail purges
