DBA_COMMON_AUDIT_TRAIL

DBA_COMMON_AUDIT_TRAIL displays all standard and fine-grained audit trail entries, mandatory and SYS audit records written in XML format.

Note:

This view is populated only in an Oracle Database where unified auditing is not enabled. When unified auditing is enabled in Oracle Database, the audit records are populated in the new audit trail and can be viewed from UNIFIED_AUDIT_TRAIL.

See Oracle Database Security Guide for more information about unified auditing.
See Oracle Database Upgrade Guide for more information about migrating to unified auditing.
