oracle 锁表相关处理

--kill session语句

alter system kill session'50,492';

--以下几个为相关表

SELECT * FROM v$lock;
SELECT * FROM v$sqlarea;
SELECT * FROM v$session;
SELECT * FROM v$process ;       
SELECT * FROM v$locked_object;   
SELECT * FROM all_objects;   
SELECT * FROM v$session_wait;

--1.查出锁定object的session的信息以及被锁定的object名

SELECT l.session_id sid, s.serial#, l.locked_mode,l.oracle_username, 
       l.os_user_name,s.machine, s.terminal, o.object_name, s.logon_time
    FROM v$locked_object l, all_objects o, v$session s
   WHERE l.object_id = o.object_id
     AND l.session_id = s.sid
ORDER BY sid, s.serial# ;

--2.查出锁定表的session的sid, serial#,os_user_name, machine name, terminal和执行的语句，比上面那段多出sql_text和action

SELECT l.session_id sid, s.serial#, l.locked_mode, l.oracle_username, s.user#,
       l.os_user_name,s.machine, s.terminal,a.sql_text, a.action  
     FROM v$sqlarea a,v$session s, v$locked_object l
    WHERE l.session_id = s.sid
      AND s.prev_sql_addr = a.address 
ORDER BY sid, s.serial#;

      
--3.查出锁定表的sid, serial#,os_user_name, machine_name, terminal，锁的type,mode 

SELECT s.sid, s.serial#, s.username, s.schemaname, s.osuser, s.process, s.machine,
       s.terminal, s.logon_time, l.type
    FROM v$session s, v$lock l
   WHERE s.sid = l.sid
     AND s.username IS NOT NULL
ORDER BY sid;

快捷拼装可以kill 的 脚本

SELECT  'alter system kill session '''|| s.sid||','||s.serial#  ||''';'
    FROM v$session s, v$lock l
   WHERE s.sid = l.sid
     AND s.username IS NOT NULL
