oracle常見錯誤_ORA-00060：等待資源時檢測到死鎖

oracle執行語句時長時間無響應，很大可能就是出現鎖表

1、查看是哪個表被鎖了

select sess.sid,
       sess.serial#,
       lo.oracle_username,
       lo.os_user_name,
       ao.object_name,
       lo.locked_mode
       from  v$locked_object lo,
       dba_objects ao,
       v$session sess
where ao.object_id = lo.object_id and lo.session_id = sess.sid;

2、殺掉鎖表進程

根據查詢出來的sid和serial#值殺掉對應進程

alter system kill session '4547,5231';   --分別為SID和SERIAL#
