Oracle审计表AUD$处理方法

Oracle版本：11.2.0，其他版本要测试DBMS_AUDIT_MGMT能否成功

1. 查询表，然后truncate

     select count(*) from aud$;
     truncate table aud$;
     select count(*) from aud$;

2.创建表空间

create tablespace adttbs 
       datafile '/oracle/OMT/admin/oradata/aud01.dbf'  size 2G autoextend on;

SELECT table_name, tablespace_name
 FROM dba_tables
 WHERE table_name IN ('AUD$', 'FGA_LOG$')
 ORDER BY table_name;

3.aud$表移动到新tablespace

BEGIN
DBMS_AUDIT_MGMT.SET_AUDIT_TRAIL_LOCATION(audit_trail_type => DBMS_AUDIT_MGMT.AUDIT_TRAIL_DB_STD,
audit_trail_location_value => 'ADTTBS');
END;
/

4.sys用户procedure：

create or replace procedure 
sp_trunc_audit_log is
begin
   execute immediate
       'truncate table aud$';
end;
授权：
grant execute on sp_trunc_audit_log to system;

5.system用户procedure：

create or replace procedure 
sp_job_trunc_audit_log is
begin
    sys.sp_trunc_audit_log;
end;

6.自动调度job

BEGIN
  DBMS_SCHEDULER.CREATE_JOB 
  (
    job_name   => 'day_trunc_audit_log',
    job_type   => 'STORED_PROCEDURE',
    job_action => 'SP_JOB_TRUNC_AUDIT_LOG',
    start_date => sysdate,
    repeat_interval => 'FREQ=DAILY; BYHOUR=04; BYMINUTE=05;INTERVAL=1',
    enabled         => true,
    comments        => 'every day truncate table audit log'
  );
END;
