The Oracle Database auditing system is a powerful, highly configurable tool for tracking operations on schema objects in a production environment. The auditing system can be used to track operations on data mining models.
Note:
To audit mining models, you must have the AUDIT_ADMIN role.
Unified auditing is documented in Oracle Database Security Guide. However, the full unified auditing system is not enabled by default. Instructions for migrating to unified auditing are provided in Oracle Database Upgrade Guide.
