編譯的存儲(chǔ)過(guò)程的時(shí)候,程序死住,等待一會(huì)出現(xiàn)ora-04021錯(cuò)誤解決辦法:

1.可能被鎖住

查看v$lockedselect b.sid,b.serial#,b.machine,b.terminal,b.PRogram,b.process,b.status from v$lock a , v$session b

where a.SID = b.SID

得到死鎖session的SID，SERIAL#參看這個(gè)是否為你自己用戶下的,然后kill掉session

2.可能被掛起

查看v$session_waitselect b.serial#,a.* from v$session_wait a,v$session bwhere a.sid = b.sid得到等待的session的sid和serial#3.查看dba_ddl_locksselect session_id sid, owner, name, type,

mode_held held, mode_requested request

from dba_ddl_locks

where name = '&your_package_name'
