–oracle提醒记录被另一个用户锁住：
–问题描述：你去修改数据时，报错“
–问题分析：你用select t.*,t.rowid from qxt_logsend_0728修改数据结果集时，计oracle会通过事务锁锁住这个记录，点击记录改变，还没提交修改时，由于网络卡死你关闭了pl/ sql,另一个人去修改同一个结果集，会报错”记录被另一个用户锁住”
–处理方法：
–1、查询数据库锁住的的sid和serial#,
select t2.username,t2.sid,t2.serial#,t2.logon_time,event,t2.BLOCKING_SESSION_STATUS
from v$locked_object t1,v$session t2
where t1.session_id=t2.sid order by t2.logon_time
–2、执行杀死session，，即可
alter system kill session ‘1059,62485’;
select /*+ ORDERED*/
sql_text
from v$sqltext a
where (a.hash_value, a.address) in
(select DECODE(sql_hash_value, 0, prev_hash_value, sql_hash_value),
DECODE(sql_hash_value, 0, prev_sql_addr, sql_address)
from v$session b
where b.sid=’1059′)
— —————————————————
–查询进程所执行的sql语句
SELECT sql_text FROM v$sqltext a WHERE a.hash_value = ( SELECT sql_hash_value FROM v$session b,
v$process c WHERE b.paddr = c.addr AND c.spid = 26568) ORDER BY piece ASC
–存过锁———————————————-
1、查看存过是否锁住，locks不等于零，表示锁住，
SELECT * FROM V$DB_OBJECT_CACHE WHERE name=’QXT_JOB’ AND LOCKS!=’0′;–name大写
2、查询存过的sid，
select SID from V$ACCESS WHERE object=’QXT_JOB’;
3、查sid和serial#，
SELECT SID,SERIAL#,PADDR FROM V$SESSION WHERE SID=’1557′;
4、杀掉进程，
alter system kill session ‘1557,14895’ immediate;
select * from V$ACCESS
