oracle 記錄被另一個用戶鎖住

oracle數據中刪除數據時提示“記錄被另一個用戶鎖住” 解決方法

1 查看數據庫鎖,診斷鎖的來源及類型
   select object_id,session_id,locked_mode from v$locked_object;
   或者用以下命令：
   select b.owner,b.object_name,l.session_id,l.locked_mode
   from v$locked_object l, dba_objects b
   where b.object_id=l.object_id

2 找出數據庫的serial#,以備殺死
   select t2.username,t2.sid,t2.serial#,t2.logon_time
   from v$locked_object t1,v$session t2
   where t1.session_id=t2.sid order by t2.logon_time;
