oracle查詢資源占用，鎖表解鎖

1. 先通過top命令查看產(chǎn)用資源較多的spid號

2.查詢當前耗時的會話ID，用戶名，sqlID等：

select sid,serial#,machine,username,program,sql_hash_value,sql_id,

? to_char(logon_time,'yyyy/mm/dd hh24:mi:ss') as login_time from v$session

where paddr in (select addr from v$process where spid in ('5648612','256523'));

3. 如果上一步sql_id或者 hash_value不為空，則可用v$sqlarea查出當前正在使用的sql

select sql_text

from v$sqltext_with_newlines

where hash_value = hash_value

order by piece;

也可直接使用:

select a.*,b.SQL_TEXT from (

select sid,serial#,machine,username,program,sql_hash_value,sql_id,

? to_char(logon_time,'yyyy/mm/dd hh24:mi:ss') as login_time from v$session

where paddr in (select addr from v$process where spid in ('23226'))

) a,v$sql b

where a.sql_id? = b.SQL_ID(+)

4.kill占用大資源的session

Alter system kill session 'SID,SERIAL#'

解鎖：

1.查詢哪些對象被鎖：

select object_name,machine,s.sid,s.serial#

from v$locked_object l,dba_objects o ,v$session s

where l.object_id　=　o.object_id and l.session_id=s.sid;

2.下面的語句用來殺死一個進程：

alter system kill session '524,1095'; (其中24,111分別是上面查詢出的sid,serial#)

3.再一次查詢目前鎖定的對象，若發(fā)現(xiàn)以上方法不能解除鎖定的表，則用以下方法：

3.1 執(zhí)行下面的語句獲得進程（線程）號：

select spid, osuser, s.program

from v$session s,v$process p

where s.paddr=p.addr and s.sid=524 （524是上面的sid）

查詢Oracle鎖表語句以及解鎖語句

查詢鎖表：SELECT l.session_id sid,

? s.serial#,

? l.locked_mode,

? l.oracle_username,

? l.os_user_name,

? s.machine,

? s.terminal,

? o.object_name,

? s.logon_time 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#;

解鎖：ALTER system KILL session 'sid,serial#';

查詢鎖住原因：SELECT b.sid oracleID,b.username 登錄Oracle用戶名,b.serial#,spid 操作系統(tǒng)ID,paddr,?

sql_text 正在執(zhí)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? and b.USERNAME='FKPHIS24';

oracle數(shù)據(jù)庫表被鎖了怎么解鎖

1、在做Oracle監(jiān)聽程序測試時，發(fā)現(xiàn)帳戶已經(jīng)被鎖定。

2、在數(shù)據(jù)庫安裝電腦上，點擊開始打開運行窗口。

3、在運行窗口輸入CMD，調(diào)出命令提示符界面。

3、在命令提示符下面，用管理員身份登入到數(shù)據(jù)庫sqlplus / as sysdba。

4、輸入解鎖命令alter user Scott account unlock后回車。

5、看見用戶已更改的字樣，表示命令已成功執(zhí)行。

6、再切換到監(jiān)聽程序驗證，原來的ora-28000帳戶被鎖定的提示已經(jīng)不存在了。用戶解鎖成功。

如何查看oracle數(shù)據(jù)庫用戶是否被鎖

這個要dba權(quán)限的用戶才能查看，具體的查看方法是 select * from dba_users 。用戶狀態(tài)一般是open（正常） locked（鎖定）expire（過期失效）幾種。
