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;
