(1)锁表查询的代码有以下的形式:
select count(*) from v$locked_object;
select * from v$locked_object;
(2)查看哪个表被锁
select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id;
(3)查看是哪个session引起的
select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;
(4)杀掉对应进程
--方法1:alter system kill session 'sid,serial#'
执行命令:alter system kill session'24,111';((其中24,111分别是上面查询出的sid,serial#)
--方法2(方法1不灵时采用):在操作系统命令行 orakill SID spid
orakill ORCL 4436
alter system kill session '26,7013';
