oracle 死锁处理，进程管理

oracle查询当前运行的进程

select a.program, b.spid, c.sql_text
from v$session a, v$process b, v$sqlarea c
where a.paddr = b.addr
and a.sql_hash_value = c.hash_value
and a.username is not null;

查询被锁的对象

SELECT a.object_id, a.session_id, b.object_name, c.*
FROM v$locked_object a, dba_objects b, v$session c
WHERE a.object_id = b.object_id
AND a.SESSION_ID = c.sid(+)

杀Seesion的SQL

　alter system kill session 'sid, serial#'

alter system kill session '53,663'

设置SQL语句计时

set timing on;
