v$lock:視圖列出當前系統持有的或正在申請的全部鎖的狀況sql
v$locked_object:視圖列出當前系統中哪些對象正被鎖定數據庫
1)、查詢當前數據庫鎖的狀況,以及致使鎖的sql語句:session
Select object_name as 對象名稱,s.sid,s.serial#,p.spid as 系統進程號,sq.SQL_TEXT From v$locked_object l , dba_objects o , v$session s , v$process p,v$sqlarea sq Where l.object_id=o.object_id and l.session_id=s.sid and s.paddr=p.addr and s.SQL_ADDRESS = sq.ADDRESS;
2)、殺掉非正常的一些鎖oop
alter system kill session 'sid,serial#';
3)、批量殺掉未釋放的鎖spa
declare cursor mycur is select b.sid,b.serial# from v$locked_object a,v$session b where a.session_id = b.sid group by b.sid,b.serial#; begin for cur in mycur loop execute immediate ( 'alter system kill session '''||cur.sid || ','|| cur.SERIAL# ||''' '); end loop; end;
