解鎖用戶及數據庫表，鎖死進程

一丶解鎖用戶
--修改時間格式
alter session set nls_date_format = 'yyyy-MM-dd hh24:mi:ss';

--查詢鎖住時間
select username,lock_date  from dba_users where username like 'ODS';

--查詢用戶狀態
select username,account_status from dba_users where username IN ('od','yxx');

--解鎖用戶
alter user yxx account unlock

 

二、解鎖數據表
--01.注意你的用戶有沒有權限問題
SELECT p.spid, a.serial#, c.object_name, b.session_id, b.oracle_username,
       b.os_user_name
  FROM v$process p, v$session a, v$locked_object b, all_objects c
 WHERE p.addr = a.paddr AND a.process = b.process
       AND c.object_id = b.object_id
---1、帶有表名稱查詢
select object_name, machine, s.sid, s.serial#
  from v$locked_object l, dba_objects o, v$session s
 where l.object_id　 = 　o.object_id
   and l.session_id = s.sid;

--2、獲取出sid,serial 用於解鎖的參數
 
  select s.username, s.osuser, s.sid, s.serial#, p.spid  from v$session s,v$process p
where s.paddr = p.addr    and s.username is not null;
--2.1、拼接sql
   select 'alter system kill session ',''''||trim(t2.sid)||','||trim(t2.serial#)||''';'
from v$locked_object t1,v$session t2 where t1.session_id=t2.sid order by t2.logon_time; 

---2：執行sql進行解鎖
alter system kill session   '198,12231';
alter system kill session   '194,37558';

 

三、解鎖鎖死系統進程
--查詢進程ID
SELECT a.username, c.spid AS os_process_id, c.pid AS oracle_process_id
  FROM v$session a, v$process c
 WHERE c.addr = a.paddr
   and a.sid =2323
   and a.serial# =213;
---kill掉進程
linux 執行：KILL -9 SPID；
window執行：orakill ORACLE_SID spid
