select b.sid oracleid,
b.username 登入oracle使用者名稱,
b.serial#,
spid 作業系統id,
paddr,
sql_text 正在執行的sql,
b.machine 計算機名
from v$process a, v$session b, v$sqlarea c
where a.addr =b.paddr
and b.sql_hash_value =c.hash_value
--檢視正在執行sql的發起者的發放程式
select osuser 電腦登入身份,
program 發起請求的程式,
username 登入系統的使用者名稱,
schemaname,

from v$session a
left join v$sql b on a.sql_address =b.address
and a.sql_hash_value =b.hash_value
order by b.cpu_time desc
--查出oracle當前的被鎖物件
select l.session_id sid,
s.serial#,
l.locked_mode 鎖模式,
l.oracle_username 登入使用者,
l.os_user_name 登入機器使用者名稱,

from v$locked_object l, all_objects o, v$session s
where l.object_id =o.object_id
and l.session_id =s.sid
order by sid, s.serial#;
--kill掉當前的鎖物件可以為
alter system kill session
'sid， s.serial#『;
select * from v$access o where o.object like '

select a.serial# from v$session a where a.sid=sid --通過sid 獲取serial#
