处理方法：
方式1：直接清理全部的审计记录
BEGIN
DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL(
audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_UNIFIED,
use_last_arch_timestamp => FALSE);
END;
/
方式三：创建定时清理的JOB
The following code can be used to combine purge job & automatic advancement of archive timestamp in one scheduler code.BEGIN
DBMS_SCHEDULER.create_job (
job_name => 'PURGE_UNIFIED_AUDIT_JOB',
job_type => 'PLSQL_BLOCK',
job_action => 'BEGIN
DBMS_AUDIT_MGMT.SET_LAST_ARCHIVE_TIMESTAMP(DBMS_AUDIT_MGMT.AUDIT_TRAIL_UNIFIED, SYSTIMESTAMP-14);
DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL(
audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_UNIFIED,
use_last_arch_timestamp => TRUE);
END;',
start_date => '',
repeat_interval => 'freq=daily; byhour=3; byminute=10; bysecond=0;',
end_date => NULL,
enabled => TRUE,
comments => 'Purge unified audit trail older than 14 days.');
END;
