Oracle數據庫表被鎖死的處理方法

(1)鎖表查詢的代碼有以下的形式： select count(*) from v$locked_object; select * from v$locked_object;
(2)查看哪個表被鎖 select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id;
(3)查看是哪個session引起的 select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;
(4)殺掉對應進程
--方法1：alter system kill session 'sid,serial#' 執行命令：alter system kill session'24,111';（(其中24,111分別是上面查詢出的sid,serial#）

--方法2（方法1不靈時采用）：在操作系統命令行 orakill SID spid  
orakill ORCL 4436 
alter system kill session '26,7013';
