Answer 1

1. 查看锁表进程SQL语句1：

被锁对象表、数据库对象表、数据session表关联来获取被锁对象对应的是那个session

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;

1. 查看锁表进程SQL语句

select * from v$session t1, v$locked_object t2 where t1.sid = t2.SESSION_ID;

1. 查看导致锁表的sql语句是那一条

select l.session_id sid, 
s.serial#, 
l.locked_mode, 
l.oracle_username, 
s.user#, 
l.os_user_name, 
s.machine, 
s.terminal, 
a.sql_text, 
a.action 
from v$sqlarea a, v$session s, v$locked_object l 
where l.session_id = s.sid 
and s.prev_sql_addr = a.address 
order by sid, s.serial#;
