官方英文解释
DBA_FGA_AUDIT_TRAIL displays all audit records for fine-grained auditing.
Note:
This view is relevant when using traditional auditing. Traditional auditing is deprecated in Oracle Database 21c. Oracle recommends that you instead use unified auditing, which enables selective and more effective auditing inside Oracle Database.
-
See Oracle Database Security
Guide for more information about unified auditing. -
See Oracle Database Upgrade
Guide for more information about migrating to unified auditing.
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.
