昨晚正在外滩玩，有个客户发过来一段报错，已经影响到业务了。一看就是12C以后版本才有的问题，，赶紧在手机中收到临时解决办法

临时处理：

SQL >  select count(*) from unified_audit_trail;

SQL >  exec dbms_audit_mgmt.clean_audit_trail(audit_trail_type=>dbms_audit_mgmt.audit_trail_unified,use_last_arch_timestamp  =>  FALSE);

SQL >  select count(*) from unified_audit_trail;
