oracle 数据处理的方式：
1。查询
2。创建表空间
3。移动到新的tablespace
4。修改，编辑procedure
5。自动调度Job
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;
