ORA-02063: preceding line from REPORT
为什么总是锁表呢，杀完了，下次还有
------解决方案--------------------
死鎖了，看看是不是 其他session 有鎖等待
select /*+rule*/
-- a.kaddr, --
(select username from v$session where sid = a.sid) username,
a.sid,
(select serial# from v$session where sid = a.sid) serial#,
-- (select ctime from v$lock where KADDR = a.kaddr) ctime, --
a.type,
a.id1,
a.id2,
a.lmode,
a.request,
a.block,
b.sid blocking_sid
from v$lock a,
( select * from v$lock
where request > 0
and type <> 'MR'
) b
where a.id1 = b.id1(+)
and a.id2 = b.id2(+)
and a.lmode > 0
and a.type <> 'MR'
order by username,a.sid,serial#,a.type
------解决方案--------------------
delete后记得commit这个transaction。
