1、查看是否有锁表的sql
- select 'blocker('||lb.sid||':'||sb.username||')-sql:'|| qb.sql_text blockers,
- 'waiter ('||lw.sid||':'||sw.username||')-sql:'|| qw.sql_text waiters
- from v$lock lb,
- v$lock lw,
- v$session sb,
- v$session sw,
- v$sql qb,
- v$sql qw
- where lb.sid=sb.sid
- and lw.sid=sw.sid
- and sb.prev_sql_addr=qb.address
- and sw.sql_address=qw.address
- and lb.id1=lw.id1
- and sw.lockwait is not null
- and sb.lockwait is null
- and lb.block=1 ;

2、查看被锁的表
- 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$locked_object b,all_objects c
- where p.addr=a.paddr and a.process=b.process and c.object_id=b.object_id ;
复制代码 3、查看那个用户那个进程造成死锁,锁的级别
- select b.owner,b.object_name,l.session_id,l.locked_mode fromv$locked_object l, dba_objects
复制代码 4、查看连接的进程
- SELECT sid, serial#, username, osuser FROMv$session;
复制代码
5、查看是哪个session引起的
- select b.username,b.sid,b.serial#,logon_time
- from v$locked_object a,v$session b
- where a.session_id = b.sid order by b.logon_time;
复制代码
6、杀掉进程
- alter system kill session 'sid,serial#';
复制代码
