/*2、批量执行第一步生成的语句
alter system kill session 'sid,serial#';
alter system kill session '6976,33967';*/

/*3、查询oracle用户名，机器名，锁表对象*/

/*3.或者*/
select s.SID, s.OSUSER, p.spid as OSPID, s.MACHINE, s.TERMINAL, s.PROGRAM
from v$session s, v$process p
where s.sid = 6 --session_id
and s.paddr = p.addr;

/*4、查询是执行何sql语句导致锁表的*/
select b.sql_text
from v$session a, v$sql b
where a.sid = 6 --session_id
and a.SQL_ADDRESS = b.ADDRESS(+);

/*5、查询是执行何sql语句导致锁表的*/
SELECT l.session_id sid,
