oracle等保，打开审计并定期清理

最近经常遇到等保需求，需要打开审计并定期清理

1、打开审计配置

SQL> alter system set audit_sys_operations=true scope=spfile;
SQL> ALTER SYSTEM SET audit_trail=DB,EXTENDED SCOPE=SPFILE;

重启后生效

2、配置保留180天，并定期清理
SQL>

variable job number;
begin
  sys.dbms_job.submit(job => :job,
    what => 'delete /*+ NOLOGGING */ sys.aud$  where trunc(NTIMESTAMP#) <= sysdate - 180;
    commit;',
    next_date => to_date('2023-07-20 00:00:00', 'yyyy-mm-dd hh24:mi:ss'),
    interval => 'sysdate+30');
  commit;
end;
/

查看JOB
set pagesize 199 linesize 199;
col WHAT for a50;
select JOB,LOG_USER,WHAT,NEXT_DATE from dba_jobs where LOG_USER='SYS';

删除JOB
exec dbms_job.remove(63);      --  根据实际情况调整
