oracle数据库查看和解除死锁

查看死锁：

select sess.sid,
sess.serial#,
lo.oracle_username,
lo.os_user_name,
ao.object_name,
lo.locked_mode,
SESS.machine
from v$locked_object lo,
dba_objects ao,
v$session sess
where ao.object_id = lo.object_id and lo.session_id = sess.sid;

杀死对应的进程：

alter system kill session 'sid,serial#'
