A.FGA is possible on SELECT statements only.
B.The audit trail for FGA is stored in the FGA_LOG$ table.
C.The audit trail for FGA is stored in the AUD_LOG$ table.
D.FGA enables a SQL predicate to define when to audit an event.
E.FGA audits DELETE statements only when audit columns are specified.
F.FGA includes the SQL statement used by the user as part of the audit event entry.

A.Set the STATISTICS_LEVEL initialization parameter to ALL.
B.Create a baseline on a pair of snapshots that have the statistics of the peak-load period in the database.
C.Decrease the snapshot interval in the AWR to collect more number of snapshots during the peak-load period.
D.Set the snapshot retention period in the Automatic Workload Repository （AWR） to zero to avoid the automatic purging of the snapshots.
