查看oracle数据库中表是否被锁

查出所有被锁住的表

select b.owner TABLEOWNER,b.object_name TABLENAME,c.OSUSER LOCKBY,c.USERNAME LOGINID, c.sid SID, c.SERIAL# SERIAL from v$locked_object a,dba_objects b,v$session c where b.object_id = a.object_id AND a.SESSION_ID =c.sid;

 

通过SID, SERIAL解锁 

alter system kill session 'SID, SERIAL';

 

查看锁表进程SQL语句

 

set pagesize 999

set line180

col ORACLE_USERNAME for a18

col OS_USER_NAME for a18

col OBJECT_NAME  for a24

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;

 

杀掉锁表进程：

alter system kill session '50,63547' immediate; 

 

批量生成语句

SELECT 'alter system kill session '''||sess.sid || ',' || sess.serial#||''' immediate;'  

    from v$locked_object lo,

    dba_objects ao,

    v$session sess

where ao.object_id = lo.object_id and lo.session_id = sess.sid;
