SQL> select xidusn, object_id, session_id, locked_mode from v$locked_object; --查死锁的对象，获取其SESSION_ID
XIDUSN OBJECT_ID SESSION_ID LOCKED_MODE
---------- ---------- ---------- -----------
10 30724 29 3
10 30649 29 3
SQL> select username,sid,serial# from v$session where sid=29; --根据上步获取到的sid查看其serial#号
USERNAME SID SERIAL#
------------------------------ ---------- ----------
QUIK 29 57107
SQL> alter system kill session '29,57107'; --删除进程，如已经删除过，则会报ora-00031的错误；否则oracle会将该session标记为killed状态，等待一段时间看能否会自动消失，如长时间消失不掉，则需要做后续步骤
alter system kill session '29,57107'
ORA-00031: session marked for kill
SQL> select pro.spid from v$session ses,v$process pro where ses.sid=29 and ses.paddr=pro.addr; --查看spid号，以便在操作系统中根据该进程号删除进程
SPID
