1.Oracle数据库查看用户锁表和对表解锁的sql语句

① 查看用户锁表

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

② 解锁语句

alter system kill session 'sid,serial#'
