-- 1. 查看被鎖的表
SELECT p.spid, a.serial#, c.object_name, b.session_id, b.oracle_username,b.os_user_name
FROM v$process p, v$session a, v$locked_object b, all_objects c
WHERE p.addr = a.paddr
AND a.process = b.process
AND c.object_id = b.object_id
-- 2. 查看是哪個進程鎖的
SELECT sid, serial#, username, status, osuser FROM v$session where serial# = '11016'

-- 3. 殺掉這個進程
alter system kill session '72,11016';

-- 4.批量解鎖
declare cursor mycur is
select b.sid,b.serial#
from v$locked_object a,v$session b
where a.session_id = b.sid group by b.sid,b.serial#;

begin
for cur in mycur
loop
execute immediate ( 'alter system kill session '''||cur.sid || ','|| cur.SERIAL# ||''' ');
end loop;
end;
