oracle锁表

-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; --查看被锁的表 select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id; --查看那个用户那个进程照成死锁 select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time; --查看连接的进程 SELECT sid, serial#, username, osuser FROM v$session; --3.查出锁定表的sid, serial#,os_user_name, machine_name,

1.查看数据库被锁的表 select a.object_name, b.session_id, c.serial#, c.program, c.username, c.command, c.machine, c.lockwait from all_objects a, v l o c k e d o b j e c t b , v locked_object b, v l o c k e d o ​ b j e c t b , v session c where a.object_id = b.object_id and c.sid = b.session_id; 2.查看表被锁的原因 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 s q l a r e a a , v sqlarea a, v s q l a r e a 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

1.查询锁表的信息 select sess.sid,sess.serial#, lo.oracle_username,lo.os_user_name, ao.object_name,lo.locked_mode from v$locked_object lo,dba_objects ao,v$session sess where ao.object_id=lo.object_id and lo.session_id=sess.sid; 杀掉进程 SQL > alter system kill session '68,51';--分别为SID和SERIAL#号 如果杀不掉则 执行一下的sql select spid, osuser, s.program from v$session s,v$process p where s.paddr=p.addr and s.sid=1065 此处的sid=1062 是 上面查询的锁表的sid 然后 kill -9 1520 (为查出来的spid号) 注意事项，如果job定时还在跑要先关掉，不然杀死又起来了 来源： https://www.cnblogs.com/JIKes/p/11777790.html

SELECT /*+ rule */ lpad(' ',decode(l.xidusn ,0,3,0))||l.oracle_username User_name, 如果发生了锁等待，我们可能更想知道是谁锁了表而引起谁的等待 找出谁锁定的记录，kill掉就行了。 alter system kill session '133,3506' ; --kill session语句 alter system kill session'50,492'; --以下几个为相关表 SELECT * FROM v$lock; --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, --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 --3.查出锁定表的sid, serial#,os_user_name, machine_name, terminal，锁的type,mode 文章来源: ORACLE锁表查询

在做数据的删除操作时，由于网络突然断开导致表被锁定，解决方方法： 先执行下面的代码： SELECT object_name, machine, s.sid, s.serial# FROM gv$locked_object l, dba_objects o, gv$session s WHERE l.object_id　= o.object_id AND l.session_id = s.sid; 查询的结果如下： 记下来查询结果中SID和SERIAL#字段的值 然后执行下面的SQL： ALTER system kill session 'SID,SERIAL# '; 好了大事告成了。 文章来源: Oracle数据库的表被锁，解决方法
