查看orAClE 锁表

Oracle数据库操作中,我们有时会用到锁表查询以及解锁和kill进程等操作,那么这些操作是怎么实现的呢?本文我们主要就介绍一下这部分内容。 (1)锁表查询的代码有以下的形式: select count(*) from v$locked_object; select * from v$locked_obj...

查看哪个表被锁 select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id 查看是哪个session引起的 select b.username,b.sid,b.serial#,logon_time from v$locked_obje...

SELECT S.SID SESSION_ID, S.USERNAME, DECODE(LMODE, 0, 'None', 1, 'Null', 2, 'Row-S (SS)', 3, 'Row-X (SX)', 4, 'Share', 5, 'S/Row-X (SSX)', 6, 'Exclusive', TO_CHAR(LMODE)) MODE_HELD, DECODE(REQUEST, 0, 'None', 1, 'Null', 2, 'Row...

--查看被锁的表 select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id; --查看那个用户那个进程照成死锁 select b.username,b.sid,b.serial#,logon_time from v$loc...

--下面的语句用来查询哪些对象被锁 select sid,serial#,username,SCHEMANAME,osuser,MACHINE, terminal,PROGRAM,owner,object_name,object_type,o.object_id from dba_objects o,v$locked_object l,v$session s where o.object_id=l.object_id a...

ORACLE EBS操作某一个FORM界面,或者后台数据库操作某一个表时发现一直出于"假死"状态,可能是该表被某一用户锁定,导致其他用户无法继续操作复制代码 代码如下:--锁表查询SQLSELECT object_name, machine, s.sid, s.serial#FROM gv$locked_obje...

用如下语句查询: 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$session sb, v$se...

查看哪个表被锁 select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id 查看是哪个session引起的 select b.username,b.sid,b.serial#,logon_time from v$locked_obje...

第一种: SQL>select session_id from v$locked_object; 49 SQL>SELECT sid, serial#, username FROM v$session where sid = 49; 49 554 system SQL>ALTER SYSTEM KILL SESSION '49, 554'; 第二种: 如果用的是客户端登录,直接关掉客户端就可以...

用如下语句查询: 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$session sb, v$se...
