oracle kill process and buffer_cache

-----------------oracle kill process----------------------------start------------------------
select * from v$session;
select sid,serial# from v$session;


--kill那个进程
alter system kill session 'sid,serial#';


--如果某应用线上有6台，每台最大连接数有10个，则machine对应一台机器应该有10条记录
--kill那个sql（先查询 sql_id,sql_hash_value）
alter system kill session 'sid,serial#';


-- oracle数据库登录名/密码：sys/oracle ---


--sysdba清数据库缓存：
alter system flush buffer_cache;


-----------------oracle kill process----------------------------start------------------------
